The corpus callosum, the largest white matter inter-hemispheric pathway, is involved in language and communication. In a cohort of 15 children and adolescents (8-15 years) with developmental absence of the corpus callosum (AgCC), this study aimed to describe language and everyday communication functioning, and explored the role of anatomical factors, social risk, and non-verbal IQ in these outcomes. Standardised measures of language and everyday communication functioning, intellectual ability and social risk were used. AgCC classification and anterior commissure volume, a potential alternative pathway, were extracted from T1-weighted images. Participants with AgCC showed reduced receptive and expressive language compared with test norms, and high rates of language and communication impairments. Complete AgCC, higher social risk and lower non-verbal IQ were associated with communication difficulties. Anterior commissure volume was not associated with language and communication. Recognising heterogeneity in language and communication functioning enhances our understanding and suggests specific focuses for potential interventions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Purpose Children with autism spectrum disorder (ASD) are at increased risk of experiencing difficulties with the development of literacy, including the emergent literacy skills recognized to underpin conventional literacy success. Comprehensive assessment is essential. Characteristics of ASD can make assessment challenging, and this can be compounded when children are unable to demonstrate their skills using spoken language. The purpose of this clinical tutorial is to outline the process of emergent literacy assessment for children with ASD who have limited verbal communication skills. A case example of a 5-year-old boy is presented. Method Pertinent literature is reviewed around the literacy profiles of children with ASD, the subgroup of children with ASD who have limited verbal communication skills, key components of emergent literacy, and previous research examining the emergent literacy abilities of children with ASD. The case report is described in depth and emphasizes the key factors to consider when designing an assessment battery and protocol. Results The case example information is interpreted, and its application is discussed. Key outcomes are highlighted including a greater understanding of the child's literacy strengths and needs and the implications for individualized instruction. Conclusion The clinical tutorial highlights the need for a comprehensive, well-planned assessment approach that involves all members of the educational team, and that is considerate to the needs of the individual child and responsive to their communication needs.

Practitioners need validated strategies for teaching children with significant multiple disabilities (e.g., cognitive, motor, and sensory disability) to use tangible symbols for expressive communication. This single-case experimental design study replicated the positive effect of an adapted protocol for teaching Phase 1 of the Picture Exchange Communication System (PECS) using tangible symbols and extended it to a younger group (4-7 years old) of learners with multiple disabilities. It also tested the effect of an adapted protocol for Phase 2 of PECS to incorporate use of a single switch speech-generating device to gain the attention of an adult communication partner. Two of three students who reached mastery in Phase 1 also reached mastery in Phase 2 and may have generalized requesting behavior from the interventionist (i.e., researchers) to their classroom teacher. Results add to the growing evidence base that shows that the adapted PECS Phase 1 procedures are a promising practice for learners with multiple disabilities, including sensory impairment, and provide preliminary evidence for a more efficient and effective approach to adapting PECS Phase 2 than previously studied for this group of learners. Directions for future research and recommendations for practice are provided.

Introduction: The patients' perception of how communication dysfunction may cause a disadvantage is important information for the clinical decision-making process. Objectives: This study aimed to translate the self-evaluation of communication experiences after laryngectomy (SECEL) to the European Portuguese (EP) and to assess its feasibility, acceptability, reliability, and validity. Material and methods: A cross-sectional study was carried out, and a cluster sample of seven ENT outpatient clinics was drawn. The EP-SECEL was filled in by 129 people with laryngectomy, aged 29-81 years and 25 of those completed it in the second time. Patients have also filled in the European Organization for Research Treatment of Cancer Quality of Life Questionnaire (EORCT), the core quality of life questionnaire (QLQ-C30) and the 35-item Head and Neck module (H&N35). Results: The EP-SECEL has the same conceptual meaning, semantics, idiomatic, format and score equivalence as the original one. Psychometric analyses revealed that it is feasible (missing <1%, to fill out took about 15 minutes for most patients), acceptable (floor and ceiling effects inferior to 15%), reliable (excellent internal consistency, Cronbach's alpha = 0.90, and moderate test-retest, Spearman's rhô = 0.64), well-constructed (66% of the total variance is explained by exploratory factor analysis), significantly convergent (correlates with the EORTC QLQ-C30 and H&N35) and validly discriminates people with total and partial laryngectomy as well as people with different primary means-of-communication. Conclusions: This study supports that the EP-SECEL has sufficient psychometric qualities to be considered an adequate tool to be recommended for assessing health-related quality of life among laryngectomy patients.

Introduction: Language dysfunction has recently been suggested to be one route to alexithymia, an impairment in recognizing and communicating one's own emotions. Neuropsychological evidence is needed to investigate the possibility that acquired language problems could underlie acquired alexithymia., Method: This project examined data from a large group of chronic stroke patients ( N = 118) to test whether self-reported or behavioral measures of language and communication problems were associated with alexithymia. We also examined the impact of hemisphere of damage on alexithymia., Results: We found no differences in alexithymia levels for patients with observed language impairments on brief tests of picture naming, comprehension, and reading vs unimpaired patients. However, self-reported communication difficulties were found to be associated with higher scores of alexithymia, even after controlling for depression and anxiety. Patients with left- versus right-hemisphere damage did not differ in their alexithymia scores., Conclusions: We found partial support for the language hypothesis of alexithymia. We discuss potential reasons for the discrepant findings between the self-report and objective language measures and suggest that self-report measures may be more sensitive to milder, more pragmatic language impairments, as opposed to the severe structural language impairments measured by the cognitive screening tests.

This was a two-phase study that aimed to (a) develop a tool for assessing visual attention in individuals with Rett syndrome using AAC with a communication partner during naturalistic interactions in clinical settings; and (b) explore aspects of the tool's reliability, validity, and utility. The Assessment of Visual Attention in Interaction (AVAI) tool was developed to assess visual attention operationalized as focused gazes (1 s or longer) at the communication partner, an object, and a symbol set. For the study, six video-recorded interactions with nine female participants diagnosed with Rett syndrome (range: 15-52-years-old) were used to calculate intra- and inter-rater agreement, and 18 recorded interactions were analyzed to examine sensitivity to change and acceptability. There was a significant difference in the AVAI results between two conditions (with and without aided-language modeling). Inter-rater agreement ranged from moderate and strong. There was a range in scores, indicating that the AVAI could differentiate between participants. The AVAI was found to be reliable, able to detect change, and acceptable to the participants. This tool could potentially be used for evaluating interventions that utilize aided AAC.

Background: Children with a significant cognitive and motor developmental delay are pre-symbolic communicators. The primary aim of this study was to reveal the variability within the communicative functioning of this group of children in terms of communication level, the reasons to communicate and behavioural expressions., Methods: Twenty-six children between 14 and 58 months with a significant cognitive and motor developmental delay were recruited. The Communication Matrix of Rowland (2011, Communication Disorders Quarterly, 32, 190) was used to integrate different sources of information on the children's communicative functioning., Results: These children primarily communicated at the level of pre-intentional and intentional behaviour, aimed at refusing, obtaining and, to a lesser extent, social purposes., Conclusions: To develop or adapt early intervention strategies, and to monitor progress in communicative development, an even more nuanced view on these children's communicative utterances in terms of frequency, duration, idiosyncrasy and context relatedness is needed., (© 2019 John Wiley & Sons Ltd.)

More people with autism spectrum disorder (ASD) are now being identified in the criminal justice system, and in parallel with this increase, the prevalence of ASD in the community has risen more than 150 % in the same time period. In this article, I will argue that this increase is due to a reclassification of those individuals whose social, communicative and behavioural function is at the lower end of the normal range. Put simply, extremes of these quantitative traits are now being conceptualised as 'disorder'. This has particular relevance for the criminal justice system as such traits are over-represented in this population: as such, it is likely that increasing numbers of people who are incarcerated will receive an ASD diagnosis. This will have major implications for where best, and how best, to manage such individuals using a framework of 'disorder' versus 'difference'., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Tic disorders are characterized by a class of responses assumed to be neurobiological in origin. Still, several studies have shown that tic frequency can be influenced by antecedent environmental events and social consequences. Prior reviews have summarized the effects of environmental events but have not examined relations between tic diagnosis, behavioral deficits (e.g., intellectual disability), tic topography, and the consequences observed to maintain tics. These variables might be important when attempting to predict or identify relevant consequences. A more thorough understanding of the variables that maintain and give rise to tics might also be useful in predicting responsiveness to treatment and intervention refinement. We reviewed and summarized results from the 13 attempts to experimentally identify maintaining consequences for tics (i.e., functional analyses) that have been published to date. We examined patterns of functions across tic diagnoses (i.e., Tourette's syndrome or not), communication impairments (i.e., an intellectual disability or reported language difficulty), and tic topography. Results suggested that individuals with Tourette's syndrome and those without communication impairments are more likely to have functional analysis outcomes consistent with automatic reinforcement, but exceptions in both directions highlight the utility of functional analysis in treating tics.

Background: Adolescents with attention-deficit hyperactivity disorder (ADHD) may have impaired social cognition and communication. However, the functioning of the brain networks involved in the social cognition and communication impairment in ADHD patients remains unclear., Methods: In total, 18 adolescents with ADHD and 16 age- and sex-matched typically developing adolescents (controls)-all of whom underwent a brain magnetic resonance imaging examination-were enrolled. Their parents filled out Swanson, Nolan, and Pelham IV (SNAP-IV) and Social Responsiveness Scale (SRS) questionnaires. Functional connectivity analyses based on the default mode network, frontoparietal network, and cinguloopercular network were performed., Results: Compared with controls, adolescents with ADHD exhibited higher total and subscale scores on SNAP-IV and SRS. Higher SNAP-IV and SRS scores were associated with higher functional connectivity between the default mode network (ventromedial prefrontal cortex) and cinguloopercular network (anterior insula) and between the FPN (dorsolateral and prefrontal cortex) and cinguloopercular network, but with lower functional connectivity between the default mode network (posterior cingulate cortex) and frontoparietal network (inferior parietal lobule) and between the default mode network (precuneus) and cinguloopercular network (temporoparietal junction)., Discussion: Social cognition and communication impairment and ADHD may commonly share the aberrant functional connectivity in the default mode network, frontoparietal network, and cinguloopercular network., Competing Interests: Declaration of Competing Interest No conflict of interest., (Copyright © 2020.

Background: People with an intellectual disability (ID) are vulnerable to communication impairments, with consequences for employment, education, and social participation., Aims: To identify the communication skills of a population of adults (40+ years) with ID and explore relationships between individual and environmental factors and communication skills., Methods and Procedures: Data from a sample of 601 adults with ID was selected from the Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing (IDS-TILDA) addressing communication characteristics, demographics, co-morbidities, challenging behaviours, and social participation. A multiple regression model and a decision-making tree were built to identify factors related to communication abilities., Outcomes and Results: Overall, 57.9 % of participants experienced communication difficulties, with 23.5 % reporting severe difficulties. Only 75.1 % of participants communicated verbally; more than half found communicating with professionals and non-familiar partners difficult. Level of ID, low social participation, challenging behaviours, and diagnosis of Down syndrome were significantly associated with communication difficulties., Conclusions and Implications: Communication difficulties are prevalent in adults with ID and are influenced by complex factors. Interventions to enhance interaction and quality of life of individuals with ID should consider communication opportunities, needs, and barriers., (Copyright © 2019 Elsevier Ltd.

Objective: To involve people living with amyotrophic lateral sclerosis (plwALS) in the scoping and identification of research priorities related to the changes in ALS communication including the use of augmentative and alternative communication (AAC). Methods: Two focus groups of plwALS at early and late stages of change to speech intelligibility were carried out as a patient and participant involvement exercise. The transcriptions of these groups were analyzed thematically and compared between groups. Results: Aspects of anticipation, preparation, adaptation and partnership were identified as key to dealing with communication change as a result of ALS. In particular the involvement of partners was clearly significant, as was the impact on them as well as the plwALS. PlwALS successfully contributed to focus groups and the process of group discussion about communication itself appeared constructive. Conclusions: Research and new interventions should focus further on how to support the partners of plwALS. Future research with plwALS should place AAC strategies and technology in the context of wider communication and investigate how best to support the anticipation, preparation and adaptation to communication change. Specific areas of research need relating to this support are suggested. IMPLICATIONS FOR REHABILITATION People living with ALS (plwALS) are rarely involved in setting the research agenda in the areas of speech and augmentative and alternative communication (AAC). Enabling plwALS to contribute to research, even those with no speech, is feasible with appropriate support. Feedback indicates that communication change and AAC are experienced in different ways by plwALS. Research and intervention should focus on how to support the anticipation, preparation and adaptation to communication change for plwALS.

Many individuals with traumatic brain injury (TBI) rely on augmentative and alternative communication (AAC) supports to meet functional communication needs. The use of images to display message content may be advantageous for this population, given deficits in literacy, visual processing, and cognition. Grid and visual scene displays are two options for presenting images within AAC systems. Eye-tracking technology was utilized to evaluate the visual processing patterns of 13 adults with a history of TBI and 13 adults without TBI when interpreting themes depicted in grid and visual scene displays. Results indicated that differential processing and effort was required when interpreting the two display types. Both groups of participants required significantly more visual fixation time and exhibited patterns consistent with greater cognitive effort when identifying themes depicted in grids compared to visual scenes (i.e., greater numbers of short fixations). The participants with TBI were overall less efficient than those without TBI when identifying themes presented in both AAC display types. These results add to the growing body of evidence indicating that visual scenes may more effectively represent complex concepts than decontextualized, grid-based images for individuals with TBI. Additional clinical implications are discussed.

Despite the importance of expressive language for individuals with autism spectrum disorder (ASD), expressive language assessments are not consistently included in ASD research and many studies do not adequately describe participants' verbal abilities. A valid and efficient measure of expressive language would facilitate consistent reporting across ASD research studies and provide data for additional analyses. The current study developed a new Autism Diagnostic Observation Schedule (ADOS-2) expressive language score and examined convergent and divergent validity in a large, well-defined sample of children with ASD. This score was highly correlated with other measures of expressive language (including parent-report, direct assessment, and clinician ratings) and less strongly correlated with measures of receptive language and nonverbal cognitive ability, providing good evidence of convergent and divergent validity.

Abnormal auditory discrimination neural processes, indexed by mismatch fields (MMFs) recorded by magnetoencephalography (MEG), have been reported in verbal children with ASD. Association with clinical measures indicates that delayed MMF components are associated with poorer language and communication performance. At present, little is known about neural correlates of language and communication skills in extremely language impaired (minimally-verbal/non-verbal) children who have ASD: ASD-MVNV. It is hypothesized that MMF delays observed in language-impaired but nonetheless verbal children with ASD will be exacerbated in ASD-MVNV. The present study investigated this hypothesis, examining MMF responses bilaterally during an auditory oddball paradigm with vowel stimuli in ASD-MVNV, in a verbal ASD cohort without cognitive impairment and in typically developing (TD) children. The verbal ASD cohort without cognitive impairment was split into those demonstrating considerable language impairment (CELF core language index <85; "ASD-LI") versus those with less or no language impairment (CELF CLI >85; "ASD-V"). Eighty-four participants (8-12 years) were included in final analysis: ASD-MVNV: n = 9, 9.67 ± 1.41 years, ASD: n = 48, (ASD-V: n = 27, 10.55 ± 1.21 years, ASD-LI: n = 21, 10.67 ± 1.20 years) and TD: n = 27, 10.14 ± 1.38 years. Delayed MMF latencies were found bilaterally in ASD-MVNV compared to verbal ASD (both ASD-V and ASD-LI) and TD children. Delayed MMF responses were associated with diminished language and communication skills. Furthermore, whereas the TD children showed leftward lateralization of MMF amplitude, ASD-MVNV and verbal ASD (ASD-V and ASD-LI) showed abnormal rightward lateralization. Findings suggest delayed auditory discrimination processes and abnormal rightward laterality as objective markers of language/communication skills in both verbal and MVNV children who have ASD. Autism Res 2019, 12: 1225-1235. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Brain imaging showed abnormal auditory discrimination processes in minimally-verbal/non-verbal children (MVNV) who have autism spectrum disorder (ASD). Delays in auditory discrimination were associated with impaired language and communication skills. Findings suggest these auditory neural measures may be objective markers of language and communication skills in both verbal and, previously-understudied, MVNV children who have ASD., (© 2019 International Society for Autism Research, Wiley Periodicals, Inc.)

There is substantial evidence of word retrieval impairment as indicated by poor performance on the category fluency test in autism spectrum disorder (ASD). However, little is known about the neural mechanisms underlying this impairment. Functional neuroimaging studies have shown that the lateral frontal cortex plays a key role in flexible word retrieval. Thus, we examined whether individuals with ASD exhibited altered frontal processing during the category fluency test using functional near-infrared spectroscopy (fNIRS). Twenty-two adolescents with high-functioning ASD (20 males) and 22 typically developing (TD) adolescents (16 males) aged 11-18 years were recruited. All underwent a category fluency paradigm, which required production of animal or means of transportation words for 1 min each although their frontal hemodynamic changes were recorded with fNIRS. We found that adolescents with ASD produced fewer animal but not transportation words (group-by-category interaction: P = 0.003), suggesting differential word retrieval impairment. In addition, unlike TD adolescents who exhibited activation primarily in lateral frontal regions during word production, adolescents with ASD had comparable activation across lateral and medial frontal regions. More importantly, this lack of lateral-medial distinction of activation, which was associated with poor word retrieval, differed significantly between groups only in the animal category (group-by-category interaction: P = 0.018). Thus, our findings implicate frontal lobe dysfunction in the impairment of differential word retrieval in adolescents with ASD. The relatively greater involvement of the medial frontopolar cortex might reflect the use of nonspecialized brain regions to compensate for the category-dependent difficulties with word retrieval in ASD. Autism Res 2019, 12: 600-613. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Using an optical imaging tool, we found that adolescents with autism had difficulties with producing semantically related words and exhibited frontal lobe dysfunction. Nonetheless, poor word production and altered brain processing was only seen when these adolescents were asked to produce words from a category of living things but not nonliving things (i.e., animals but not means of transportation). Category-dependent word retrieval problems and frontal lobe dysfunction might be two features of this disorder., (© 2019 International Society for Autism Research, Wiley Periodicals, Inc.)

Purpose Research manipulating the complexity of housing environments for healthy and brain-damaged animals has offered strong, well-replicated evidence for the positive impacts in animal models of enriched environments on neuroplasticity and behavioral outcomes across the lifespan. This article reviews foundational work on environmental enrichment from the animal literature and considers how it relates to a line of research examining rich communicative environments among adults with aphasia, amnesia, and related cognitive-communication disorders. Method Drawing on the authors' own research and the broader literature, this article first presents a critical review of environmental complexity from the animal literature. Building on that animal research, the second section begins by defining rich communicative environments for humans (highlighting the combined effects of complexity, voluntariness, and experiential quality). It then introduces key frameworks for analyzing and designing rich communicative environments: distributed communication and functional systems along with sociocultural theories of learning and development in humans that support them. The final section provides an overview of Hengst's and Duff's basic and translational research, which has been designed to exploit the insights of sociocultural theories and research on environmental complexity. In particular, this research has aimed to enrich communicative interactions in clinical settings, to trace specific communicative resources that characterize such interactions, and to marshal rich communicative environments for therapeutic goals for individuals with aphasia and amnesia. Conclusions This article concludes by arguing that enriching and optimizing environments and experiences offers a very promising approach to rehabilitation efforts designed to enhance the reorganization of cognitive-communicative abilities after brain injury. Such interventions would require clinicians to use the principles outlined here to enrich communicative environments and to target distributed communication in functional systems (not the isolated language of individuals).

Rett syndrome (RTT) is an X-linked genetic disorder that occurs predominantly in females. The clinical picture associated with RTT is defined by core and supportive consensus criteria, with a period of behavioural regression being a conditio sine qua non. This review sheds light on atypical neurofunctions and potential behavioural biomarkers before the onset of regression. The main focus lies on (a) motor development, especially on purposeful hand movements and the occurrence of stereotypies; and (b) speech-language and socio-communicative development. We outline potentially specific atypical behavioural patterns in these domains (e.g., vocalisations on inspiratory airstream) and different developmental traits of regression: (i) non-achievement of certain milestones: 'regression', here, might point to the fact that the lack of respective behavioural patterns appeared more and more worrisome with increasing age; and (ii) developmental milestones were achieved and functions deteriorate or even get lost during regression. To conclude, we are not quite there yet, but seem to be on the right track towards defining new and reliable neurofunctional markers for early detection of RTT., (Copyright © 2019 The Authors.

For individuals who rely on speech-generating devices (SGDs) to complement and substitute for spoken language, speed, and accuracy of access to the device are paramount for effective communication. There is some evidence that application of motor memory principles may improve effectiveness of SGD-based communication. This article reviews motor learning models and principles, including learning stages, types of practice, and environmental factors that affect learning, and highlights the potential applications of these principles in dynamic display SGD design, intervention, and research.

This study assessed white matter microstructural integrity and behavioral correlates for children with severe congenital hypothyroidism (CH) who were identified and treated early following newborn screening. Eighteen children with severe CH and 21 healthy controls underwent a battery of behavioral measures of hearing, language and communication, along with diffusion MR imaging. Tract-based spatial statistics were performed on standard diffusion parameters of fractional anisotropy and diffusivity metrics. Microscopic diffusion anisotropy mapping based on the Spherical Mean Technique was also used to evaluate biologically specific metrics. Compared with age-matched controls, children with severe CH had poorer hearing and communication skills, albeit generally within normal limits. Children with severe CH had fractional anisotropy that was significantly lower in the cerebellum, bilateral thalami and right temporal lobe, and radial diffusivity that was significantly higher in the cerebellum and bilateral thalami. Microscopic fractional anisotropy and intra-neurite volume fraction were also significantly decreased, and transverse microscopic diffusivity was significantly increased, in the CH group in areas including the cerebellum, thalamus, occipital lobe, and corpus callosum, and in the white matter adjacent to sensorimotor cortex, particularly in the left hemisphere. Significant and widespread correlations were observed between behavioral measures and measures of white matter microstructural integrity in children with CH. The results indicate that children with severe CH who are identified through newborn screening may have significant brain white matter microstructural abnormalities despite early treatment., (Copyright © 2019 The Authors.

New technologies designed to improve the communication of autistic children can also help to promote interaction processes and cognitive and social development. The aim of this study was to analyze the instruments used to improve the communication skills of children with autism spectrum disorder. We searched the PubMed and Web of Science databases using the descriptors "autism", "Asperger", "education", "children" and "assistive technology" and selected articles that met the following inclusion criteria: (i) original research; (ii) written in English; (iii) based on participants with a primary diagnosis of autism spectrum disorder; and (iv) tested an instrument designed to promote communication in children with autism spectrum disorder. Our search retrieved 811 articles, of which 34 met the inclusion criteria. Data on 26 instruments were extracted, and the measurement properties of the instruments were combined with information about their outcomes and presentation. The most commonly used interventions were the Treatment and Education of Autistic and Related Communication Handicapped Children program and the Picture Exchange Communication System. The Treatment and Education of Autistic and Related Communication Handicapped Children program was shown to produce improvements in the communication skills, socialization and self-care skills of children with autism spectrum disorder. The Picture Exchange Communication System produced inconsistent results. The results of the identified studies confirm the significant importance of these instruments in improving the communicative process of autistic children.

Purpose: The field of communication sciences and disorders (CSD) faces a critical shortage of the faculty essential to train the future workforce of speech-language pathologists and audiologists. Despite a predominance of women in the field, men receive doctoral degrees, tenure status, academic leadership positions, and American Speech-Language-Hearing Association awards at disproportionately higher rates than women. The purpose of this review is to explore how implicit gender bias may contribute to female faculty advancement, including current and projected faculty workforce shortages, and to propose tangible solutions., Method: The authors present proportions of men and women who receive doctoral degrees, advance to each faculty rank, receive tenure status, hold department chairs in CSD, and receive American Speech-Language-Hearing Association honors and awards. They review ways in which cultural stereotypes give rise to implicit gender bias and discuss myriad ways that implicit gender bias may influence the decisions of students considering an academic career in CSD and their career trajectories., Conclusions: Cultural stereotypes about men and women lead to implicit gender bias that may have real consequences for female faculty advancement in CSD. Such implicit bias can influence career selection and outcomes within the field in multiple ways. To ensure that CSD continues to attract top talent and maintain a robust pipeline of future faculty in doctoral training programs, the field must recognize the existence of implicit gender bias and implement evidence-based strategies to minimize its potentially damaging effects on the future of the profession.

The aim of the current systematic review was to synthesise the research that has investigated thought disorder (TD) using task-based functional neuroimaging techniques to target executive, language, or semantic functions. Thirty-five pertinent studies were identified from January 1990 to August 2016. Functional correlates of TD included the superior and middle temporal, fusiform, and inferior frontal gyri bilaterally, as well as the left and right cingulate cortex, the right caudate nucleus, and the cerebellum. TD-related increases and decreases in activation were both evident in most of these regions. However, the specificity of these correlates from general clinical and cognitive influences is unknown. The cortical regions implicated overlap with those thought to contribute to language and semantic systems. Cortico-striatal circuitry may also play a role in some aspects of TD through aberrant salience representation and inappropriate attentional prioritisation. To advance the field further, greater integration across structural, functional, and behavioural measures is required, in addition to non-unitary considerations of TD., (Copyright © 2018 Elsevier Ltd.

Communication impairment is common in Parkinson's disease (PD) and may have both motor speech control and cognitive-linguistic underpinnings. The neurobiology of communication impairment in PD is poorly understood, and work is needed to disentangle the relative contributions of motor and cognitive dysfunction. In clinical practice, cognitive-linguistic impairments are often overlooked despite the large body of research on this topic in neurocognitive and linguistics literature. In this review, we will discuss the roles of motor speech changes, cognitive and linguistic impairment, and other related functions in the communication disabilities of individuals with PD. We will describe the various types of communication difficulties in PD and tools for measuring these symptoms. We will discuss specific deficits that may further understanding of the neurobiology of communication impairment in PD, including voice and speech acoustic changes, linguistic processing and production difficulties, and pausing. We will emphasize the importance of an interdisciplinary approach and the patient perspective on daily communication in guiding future research., (Copyright © 2018 Elsevier Inc.

Objective: To determine the frequency and relative importance of symptoms experienced by adults with spinal muscular atrophy (SMA) and to identify factors that are associated with a higher burden of disease in this population., Methods: We conducted a cross-sectional study of 359 adults with SMA using the International SMA Patient Registry. Participants provided input regarding 20 symptomatic themes and 207 symptoms that potentially affect adults with SMA. Participants were asked about the relative importance of each symptom, and analysis was conducted to determine how age, sex, SMA type, education, mobility, and employment status relate to symptom prevalence., Results: Limitations with mobility or walking (98.6%) and the inability to do activities (98.6%) were the 2 themes with the highest prevalence in the study sample. Limitation with mobility or walking was the theme that was identified as having the greatest effect on the lives of adults with SMA. Employment status was associated with the prevalence of 4 of 20 themes and a reliance on an assistive device was associated with 7 of 20 themes. The prevalence of breathing difficulties, choking or swallowing difficulties, and communication difficulties differed among those with different SMA types., Conclusions: There are many symptomatic themes that affect the lives of adults with SMA. These themes vary in prevalence and relative importance in the adult SMA population., (© 2018 American Academy of Neurology.)

Purpose: Characterize the performance of outpatients regarding aspects of communication disorders according to the categories of the International Classification of Functioning, Disability and Health - Children and Youth Version (ICF-CY)., Methods: This is a descriptive, observational study based on a retrospective analysis of secondary data collected at a Speech-language Pathology outpatient clinic of the public health network, from records of patients aged 5-16 years, evaluated between 2010 and 2014. Elements of anamnesis and assessment reports were analyzed with identification of ICF-CY categories related to the following components: Body Functions, Activities and Participation, and Environmental Factors. These categories were defined as the study variables, stored as categorical variables, and had their frequency distribution investigated by descriptive statistical analysis., Results: One hundred eighty medical records were included in the study, and 65 of the 168 pre-selected categories were identified. As for the component Body Functions, 13 items were verified, with the category related to impairment in Mental functions of language as the most frequently mentioned. Of the 34 categories identified in the component Activities and Participation, Learning to read - Performance and Doing housework - Performance were the ones that most frequently presented difficulties. Of the 18 categories of the component Environmental Factors, the one described in most reports as Barrier was Individual attitudes of acquaintances, peers, colleagues, neighbors, and community members., Conclusion: Changes were found in categories of the three components of the ICF-CY analyzed, indicating the existence of issues that affected the functional performance regarding aspects of communication disorders of children and adolescents assisted at an outpatient environment.

Purpose: Brain-computer interfaces (BCIs) can provide access to augmentative and alternative communication (AAC) devices using neurological activity alone without voluntary movements. As with traditional AAC access methods, BCI performance may be influenced by the cognitive-sensory-motor and motor imagery profiles of those who use these devices. Therefore, we propose a person-centered, feature matching framework consistent with clinical AAC best practices to ensure selection of the most appropriate BCI technology to meet individuals' communication needs., Method: The proposed feature matching procedure is based on the current state of the art in BCI technology and published reports on cognitive, sensory, motor, and motor imagery factors important for successful operation of BCI devices., Results: Considerations for successful selection of BCI for accessing AAC are summarized based on interpretation from a multidisciplinary team with experience in AAC, BCI, neuromotor disorders, and cognitive assessment. The set of features that support each BCI option are discussed in a hypothetical case format to model possible transition of BCI research from the laboratory into clinical AAC applications., Conclusions: This procedure is an initial step toward consideration of feature matching assessment for the full range of BCI devices. Future investigations are needed to fully examine how person-centered factors influence BCI performance across devices.

Purpose: This article presents a systematic review that aimed to synthesize single-subject-design studies that have examined naturalistic interventions for teaching the expressive use of speech-generating devices (SGDs) to children with complex communication needs. Specifically, this review describes what intervention strategies are most commonly applied in studies with positive effects and minimal methodological flaws and examines the populations and outcomes for which these strategies have been effective., Method: A systematic approach was used to qualitatively code variables of interest to this review. Results were summarized via both visual analysis and effect size methods, and a certainty of evidence methodology was adopted to describe the quality of the evidence., Results: Thirty-two unique studies met inclusion criteria, with 19 having consistent positive results and meeting minimum requirements for certainty of evidence. Although studies used a variety of titles to describe intervention packages (e.g., milieu teaching, interaction strategies), certain strategies were common across studies. These included (a) creating and capturing communication opportunities via methods such as time delay and questioning; (b) providing feedback via methods such as reinforcement of requests, praise, or expansions; (c) prompting (verbal, physical, gestural); (d) modeling; and (e) training communication partners., Conclusions: Findings regarding these intervention components help to provide practical guidelines for naturalistic SGD intervention. Limitations of the current body of research (e.g., need to include more home-based studies and more intermediate to advanced SGDs, need to critically analyze the most critical intervention components) provide suggestions for future research., Supplemental Material: https://doi.org/10.23641/asha.6615332.

Impairments in social communication (coupled with intact nonsocial language skills) are common in autism spectrum disorder (ASD). However, the neural correlates of these social communication deficits in adolescents and young adults with ASD are not fully understood. The communication checklist self-report (CC-SR) was administered to adolescents and young adults with ASD (n = 52) and typically developing (TD) controls (n = 64) to assess structural-language, pragmatic-language, and social-engagement. One high-resolution T1-weighted structural image was obtained from each participant. FreeSurfer was used to quantify cortical thickness. A main effect of diagnosis, with the ASD group performing worse than the TD group on all three CC-SR scales, and a diagnosis by scale interaction, driven by low social-engagement self-ratings in the ASD group, were found. There were also group differences in the relationship between scores on two of the three CC-SR scales and cortical thickness in multiple regions (pragmatic-language: left rostral frontal; social-engagement: left medial prefrontal). These interactions were driven by poorer self-ratings of language/social skills associated with decreased cortical thickness in the ASD group, while in the TD group worse self-ratings were associated with thicker cortex. Self-ratings of language/social-communication were lower in the ASD than the TD group. Moreover, language/social-communication self-ratings showed a different relationship with cortical thickness for the ASD and TD groups in the left inferior frontal region for pragmatic language ratings and the left medial prefrontal cortex for social engagement ratings. These findings suggest thinner cortex is associated with more impaired pragmatic language and social communication abilities in ASD.

LAY SUMMARY: The present study examines the associations between brain structure and language/social communication ability in adolescents and young adults with autism spectrum disorder (ASD) as compared to neurotypical adolescents and young adults. We utilized thickness of the cerebral cortex as a measure of brain structure, and we found different correlations between language or social communication ability and cortical thickness in distinct regions for the ASD and TD groups. These findings suggest that for regions implicated in language/social communication ability, decreased cortical thickness is associated with more impaired pragmatic language and social communication abilities in ASD., (© 2018 International Society for Autism Research, Wiley Periodicals, Inc.)

This study aimed to reveal electrophysiological markers of communicative and cognitive dysfunctions of different severity in children with autism spectrum disorder (ASD). Eyes-opened electroencephalograms (EEGs) of 42 children with ASD, divided into two groups according to the severity of their communicative and cognitive dysfunctions (24 with severe and 18 children with less severe ASD), and 70 age-matched controls aged 4-9 years were examined by means of spectral and group independent component (gIC) analyses. A predominance of theta and beta EEG activity in both groups of children with ASD compared to the activity in the control group was found in the global gIC together with a predominance of beta EEG activity in the right occipital region. The quantity of local gICs with enhanced slow and high-frequency EEG activity (within the frontal, temporal, and parietal cortex areas) in children 4-9 years of age might be considered a marker of cognitive and communicative dysfunction severity., (Copyright © 2018 Elsevier B.V.

Children with severe motor impairments are restricted in their manipulation and exploration of objects, but little is known about how such limitations influence cognitive development. This study investigated visual-constructional abilities in 75 children and adolescents, aged 5;0-15;11 (years;months), with severe speech impairments and no intellectual disabilities (aided group) and in 56 children and adolescents with typical development (reference group). Verbal comprehension, non-verbal reasoning, and visual-spatial perception were assessed with standardized tests. The task of the participants was to verbally instruct communication partners to make physical constructions identical to models that the partner could not see. In the aided group, 55.7% of the constructions were identical to the models participants described, compared to 91.3% in the reference group. In the aided group, test results explained 51.4% of the variance in construction errors. The results indicate that the participants' language skills were decisive for construction success. Visual-perceptual challenges were common among the aided communicators, and their instructions included little information about size and spatial relations. This may reflect less experience with object manipulation and construction than children with typical development, and using aided communication to instruct others to make three-dimensional constructions. The results imply a need for interventions that compensate for the lack of relevant experience.

There is limited knowledge about aided language comprehension and use in children who use aided communication and who are considered to have a relatively good comprehension of spoken language. This study's purpose was to assess their aided language skills. The participants were 96 children and adolescents who used communication aids (aided group) and 73 children and adolescents with natural speech (reference group), aged 5 to 15 years. All of the participants who used aided communication were regarded by their teachers or professionals as having age-appropriate language comprehension. All of the participants completed (a) standardized tests of visual perception, non-verbal reasoning, and comprehension of spoken language, and (b) tasks designed for this study that measured comprehension and production of graphic utterances through communicative problem solving. Using their own communication systems, the participants achieved an average of 72% correct on the graphic symbol comprehension task items, and 63% on the expressive tasks. The participants with natural speech achieved an average of 88% correct on comprehension items, and 93-96% accuracy on production items. The differences between groups were significant on all the tasks and standardized tests. There was considerable variation within the group of participants who used aided communication, and the results reveal a need to develop instruments with norms for aided language competence that can inform the implementation of interventions to support aided language development.

Background: Although a bidirectional relationship between autism spectrum disorder (ASD) and anxiety symptoms is assumed, few studies have investigated this. Moreover, little is known about potential differential relationships of the two core symptom domains of ASD - social communication impairment and restricted, repetitive behavior - with anxiety over time., Method: Participants were 130 children with an ASD (M age 6.7 years, 81.5% boys) of whom 79 participated in a follow-up assessment 2 years later. We used cross-lagged models to test whether social communication impairment and restricted, repetitive behavior at T0 predicted anxiety at T2 and vice versa., Results: Crossed-lagged models showed that anxiety symptoms predicted social communication impairment over time (β = .22, p = .008), but not vice versa (β = -.07, p = .49). There were no significant paths from anxiety symptoms to later restricted, repetitive behavior (β = .11, p = .34) or vice versa (β = -.11, p = .27)., Conclusions: Our results do not support a bidirectional relationship between the ASD core symptom domains and anxiety, but suggest that higher levels of anxiety symptoms increase the risk of more social communication impairment over time in children with ASD. This underlines the importance of treating anxiety symptoms to improve both social and emotional functioning., (© 2017 Association for Child and Adolescent Mental Health.)

WeChat represents one of the most popular smartphone-based applications for communication. Although the application provides several useful features that simplify daily life, a growing number of users spend excessive amounts of time on the application. This may lead to interferences with everyday life and even to addictive patterns of use. In the context of the ongoing discussion on Internet Communication Disorder (ICD), the present study aimed to better characterize the addictive potential of communication applications, using WeChat as an example, by examining associations between individual variations in tendencies towards WeChat addiction and brain structural variations in fronto-striatal-limbic brain regions. To this end levels of addictive tendencies, frequency of use and structural MRI data were assessed in n = 61 healthy participants. Higher tendencies towards WeChat addiction were associated with smaller gray matter volumes of the subgenual anterior cingulate cortex, a key region for monitoring and regulatory control in neural networks underlying addictive behaviors. Moreover, a higher frequency of the paying function was associated with smaller nucleus accumbens volumes. Findings were robust after controlling for levels of anxiety and depression. The present results are in line with previous findings in substance and behavioral addictions, and suggest a similar neurobiological basis in ICD.

Patients with schizophrenia usually show an impairment in their communicative-pragmatic performance; they also have difficulties in cognitive functioning and Theory of Mind (ToM). In the literature it has been proposed that ToM and cognitive deficits have a role in explaining the communicative-pragmatic difficulties of patients with schizophrenia. However, the exact interplay of these functions is still not completely clear. The present research investigates the relationship between communicative-pragmatic, ToM and cognitive impairments (i.e. general intelligence, selective attention, speed processing and EF -working memory, inhibition and flexibility-) in a sample of 26 individuals with schizophrenia and matched controls. The linguistic and extralinguistic scales of the Assessment Battery of Communication (ABaCo), and a series of ToM and cognitive tasks were administered to patients and healthy controls. The results showed that individuals with schizophrenia performed less well than controls in all the tasks investigated. However, a hierarchical regression analysis showed that only ToM, and not cognitive functions, seems to be a predictive variable of patients' performance. Finally, a Fisher's exact test showed that there was not a stable significant relationship between ToM or EF and pragmatic impairment., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Purpose: The Communication Function Classification System (CFCS) and Viking Speech Scale (VSS) are useful systems for describing the broad communication function and speech intelligibility, respectively, of children with cerebral palsy (CP). The aims of this study were to determine the reliability and validity of the Korean version of the CFCS and also to investigate the association between the CFCS and the VSS and other functional classifications for children with CP., Materials and Methods: Participants were 50 children with CP (33 males, 17 females; mean age 7.2 years, range 4-16 years) recruited from a rehabilitation hospital. We analysed the interrater and intrarater reliabilities of the Korean version of the CFCS and VSS between parents, a physiatrist, and a speech-language pathologist (SLP). The social function domain of the Paediatric Evaluation of Disability Inventory was assessed to examine the concurrent validity of the CFCS and VSS., Results: The intrarater reliabilities of the CFCS and VSS were excellent in a physiatrist (ƙ = 0.92, ƙ = 0.94, respectively) and an SLP (ƙ = 0.98, ƙ = 0.98) and very good in parents (ƙ = 0.87, ƙ = 0.89). The interrater reliability of the CFCS and VSS was very good between the physiatrist and SLP (ƙ = 0.87, ƙ = 0.89) and good between parents and the SLP (ƙ = 0.63, ƙ = 0.78) and between parents and the physiatrist (ƙ = 0.61, ƙ = 0.76). The CFCS and VSS were strongly related with the social function domain of Paediatric Evaluation of Disability Inventory. In addition, we found very strong associations between the VSS and CFCS., Conclusions: The Korean version of the CFCS is a valid and reliable tool to classify communication ability and is strongly associated with the VSS, a reliable tool to classify speech intelligibility., (© 2017 John Wiley & Sons Ltd.)

Literature indicates that some children with ASD may show behavioral improvements during fever; however, little is known about the behavioral profiles of these children. This study aims to (a) investigate the subset of children who show parent-reported behavioral improvements associated with fever and (b) compare the demographic, behavioral, and genetic characteristics of this subset of children to children whose parents report no change during fever. Parents of 2,152 children from the Simons Simplex Collection provided information about whether and in which areas their child improved during fever. Children were randomly assigned into discovery or replication samples. In discovery analyses, children who reportedly improved with fever (Improve Group) were compared to those who reportedly did not improve (No Improve Group) on demographics, medical history, ASD symptoms, adaptive skills, and presence of de novo ASD-associated mutations. Significant and marginal results from discovery analyses were tested in the replication sample. Parent reports of 17% of children indicated improvements during fever across a range of domains. Discovery and replication analyses revealed that the Improve Group had significantly lower non-verbal cognitive skills (NVIQ) and language levels and more repetitive behaviors. Groups did not differ on demographic variables, parent-report of current ASD symptoms or the presence of de novo mutations. Understanding the profiles of children who improve during episodes of fever may provide insights into innovative treatments for ASD. Autism Res 2018, 11: 175-184. © 2017 International Society for Autism Research, Wiley Periodicals, Inc., Lay Summary: This study explored characteristics of children with ASD who are reported to improve during fever. Parents of 17% of children with ASD report improvements across a range of domains during fever including cognition, communication, repetitive behaviors, social interaction, and behavior. Children who are reported to improve during fever have significantly lower non-verbal cognitive skills and language levels and more repetitive behaviors. Understanding the profiles of children who improve during episodes of fever may provide insights into new treatments for ASD., (© 2017 International Society for Autism Research, Wiley Periodicals, Inc.)

Purpose: There is a need for speech-language pathology (SLP) research in the Philippines, in order to fill in knowledge gaps relevant to the local context. Information about the local SLP research status remains inadequate. This study describes local SLP research done over the almost past four decades., Method: Using a descriptive retrospective design, a search was made for all empirical research articles completed by Filipino SLPs from 1978 to 2015., Result: A total of 250 research articles were identified and described along several parameters. A predominant number were authored by the SLPs in the academe (97.20%). There was a focus on language (27.60%) and the nature of communication/swallowing disorders (20.80%). More than half utilised quantitative exploratory research designs (69.20%). Several used survey forms to generate data (38.41%). Nearly all were unpublished (93.60%) and were unfunded (94.80%)., Conclusion: The current study revealed a dearth of research studies, limited diversity of research articles, limited research dissemination and funding concerns. It is suggested that the results of the current study can serve as a reference point to restructure research systems in the Philippines and in other developing countries, and offer data that can be used to develop a research agenda for the profession.

This study in programmatic research on technology-supported instruction first identified, through pretesting using evidence-based criteria, students with persisting specific learning disabilities (SLDs) in written language during middle childhood (grades 4-6) and early adolescence (grades 7-9). Participants then completed computerized writing instruction and posttesting. The 12 computer lessons varied output modes (letter production by stylus alternating with hunt and peck keyboarding versus by pencil with grooves alternating with touch typing on keyboard), input (read or heard source material), and task (notes or summaries). Posttesting and coded notes and summaries showed the effectiveness of computerized writing instruction on both writing tasks for multiple modes of language input and letter production output for improving letter production and related writing skills.

Purpose: Augmentative and alternative communication (AAC) promotes communicative participation and language development for young children with complex communication needs. However, the motor, linguistic, and cognitive demands of many AAC technologies restrict young children's operational use of and influence over these technologies. The purpose of the current study is to better understand young children's participation in programming vocabulary "just in time" on an AAC application with minimized demands., Method: A descriptive study was implemented to highlight the participation of 10 typically developing toddlers (M age: 16 months, range: 10-22 months) in just-in-time vocabulary programming in an AAC app with visual scene displays., Results: All 10 toddlers participated in some capacity in adding new visual scene displays and vocabulary to the app just in time. Differences in participation across steps were observed, suggesting variation in the developmental demands of controls involved in vocabulary programming., Conclusions: Results from the current study provide clinical insights toward involving young children in AAC programming just in time and steps that may allow for more independent participation or require more scaffolding. Technology designed to minimize motor, cognitive, and linguistic demands may allow children to participate in programming devices at a younger age.

In recent decades, embodiment has become an influential concept in psychology and cognitive neuroscience. Embodiment denotes the study of the reciprocal (causal) relationships between mind and body, with the mind not only affecting the body but also vice versa. Embodied cognition comes to the fore in sensorimotor coupling, predictive coding, and nonverbal behavior. Additionally, the embodiment of the mind constitutes the basis of social interaction and communication, as evident in research on nonverbal synchrony and mimicry. These theoretical and empirical developments portend a range of implications for schizophrenia research and treatment. Sensorimotor dysfunctions are closely associated with affective and psychotic psychopathology, leading to altered timing in the processing of stimuli and to disordered appraisals of the environment. Problems of social cognition may be newly viewed as disordered embodied communication. The embodiment perspective suggests novel treatment strategies through psychotherapy and body-oriented interventions, and may ultimately provide biomarkers for diagnosis., (© The Author 2017.

Background: Understanding how emotional faces are processed is important to help characterize the social deficits in Autism Spectrum Disorder (ASD)., Aims: We examined: (i) whether attention is modulated by emotional facial expression; (ii) the time course of the attentional preferences (short vs. long stimulus presentation rates); and (iii) the association between attentional biases and autistic symptomatology., Method and Procedures: We applied a dot-probe experiment with emotional faces (happy, sad, and angry). The sample was composed of ASD children without additional language and/or intellectual impairments (n=29) and age-matched Typically Developing (TD) children (n=29)., Outcomes and Results: When compared to the TD group, the ASD group showed an attentional bias away from angry faces at long presentation rates. No differences between groups were found for happy or sad faces. Furthermore, correlational analyses showed that the higher avoidance of angry faces, the greater are the social communication difficulties of ASD children. The attentional bias away from angry faces may be an underlying mechanism of social dysfunction in ASD. We discuss the implications of these findings for current theories of emotional processing in ASD., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Purpose Reading comprehension can change following acquired brain injury (ABI), impacting independence and participation. This review aims to identify and evaluate the interventions used for rehabilitation of discourse level reading in adults with ABI. Methods A systematic review was conducted of published journal articles. Methodological quality of studies was reviewed using formal and informal rating scales. Inclusion criteria involved adults with non-progressive ABI who experienced discourse level reading deficits related to aphasia or cognitive-communication disorders. Results A total of 23 studies were identified; these included randomized controlled trials, cohort and case studies. Six different types of reading interventions were found, overall results of these interventions were mixed. Reading deficits were reportedly related to language (aphasia) and/or cognitive deficits, with assessment processes varying. Questions arose regarding comparability of assessment methods and diagnostic issues across the studies. Conclusions Interventions for discourse level reading comprehension can make positive changes to reading function. However, no intervention was identified as a gold standard. A trend toward strategy-based reading was found, with these offering a potential for (comparatively) cost-effective lower-dosage reading treatments with positive-trend results. Cognitive and language features should be considered for assessment and intervention planning for discourse reading in ABI. Implications for Rehabilitation Six different types of discourse reading comprehension interventions for people with ABI were identified, with mixed evidence for each intervention. Clinicians need to consider both the linguistic and cognitive features of reading for assessment and intervention planning for discourse level reading. There is a research trend toward strategy-based reading interventions, which use a lower treatment dosage.

Many children with autism spectrum disorder (ASD) have notable difficulties in motor, speech and language domains. The connection between motor skills (oral-motor, manual-motor) and speech and language deficits reported in other developmental disorders raises important questions about a potential relationship between motor skills and speech-language deficits in ASD. To this end, we examined data from children with ASD (n = 1781), 2-17 years of age, enrolled in the Autism Speaks-Autism Treatment Network (AS-ATN) registry who completed a multidisciplinary evaluation that included diagnostic, physical, cognitive and behavioral assessments as part of a routine standard of care protocol. After adjusting for age, non-verbal IQ, Attention Deficit Hyperactivity Disorder (ADHD) medication use, and muscle tone, separate multiple linear regression analyses revealed significant positive associations of fine motor skills (FM) with both expressive language (EL) and receptive language (RL) skills in an impaired FM subgroup; in contrast, the impaired gross motor (GM) subgroup showed no association with EL but a significant negative association with RL. Similar analyses between motor skills and interpersonal relationships across the sample found both GM skills and FM skills to be associated with social interactions. These results suggest potential differences in the contributions of fine versus gross motor skills to autistic profiles and may provide another lens with which to view communication differences across the autism spectrum for use in treatment interventions.

Laughter and smile are typical expressions of mirth and fundamental means of social communication. Despite their general interest, the current knowledge about the brain regions involved in the production of these expressions is still very limited, and the principal insights come from electrical stimulation (ES) studies in patients, in which, nevertheless, laughter or smile have been elicited very rarely. Previous studies showed that laughter is evoked by the stimulation of nodes of an emotional network encompassing the anterior cingulate, the superior frontal and basal temporal cortex. A common feature of these stimulation studies is that the facial expression was always accompanied by motor awareness and often by mirth, in line with the affective functions attributed to these regions. Little is known, in contrast, on the neural basis of the voluntary motor control of this expression. The objective of this study was to investigate the effect of ES of the frontal operculum (FO), which is considered a crucial node for the linkage of the voluntary motor system for emotional expression and limbic emotional network. We report the case of ES applied to the frontal operculum (FO) in four patients with drug-resistant focal epilepsy undergoing stereo-electroencephalographic (SEEG) implantation of intracerebral electrodes. In all patients, ES applied to the FO produced laughter or smile. Interestingly, in one patient, the production of a smiling expression was also clearly accompanied by the lack of motor awareness. Since the lack of motor awareness has been previously observed only after the stimulation of the voluntary motor network, we speculate that FO is involved in the voluntary control of facial expressions, and is placed at the interface with the emotional network, gating limbic information to the motor system., (Copyright © 2016 Elsevier Ltd.

Alterations in SHANK genes were repeatedly reported in autism spectrum disorder (ASD). ASD is a group of neurodevelopmental disorders diagnosed by persistent deficits in social communication/interaction across multiple contexts, with restricted/repetitive patterns of behavior. To date, diagnostic criteria for ASD are purely behaviorally defined and reliable biomarkers have still not been identified. The validity of mouse models for ASD therefore strongly relies on their behavioral phenotype. Here, we studied communication by means of isolation-induced pup ultrasonic vocalizations (USV) in the Shank1 mouse model for ASD by comparing Shank1(-/-) null mutant, Shank1(+/-) heterozygous, and Shank1(+/+) wildtype littermate controls. The first aim of the present study was to evaluate the effects of Shank1 deletions on developmental aspects of communication in order to see whether ASD-related communication deficits are due to general impairment or delay in development. Second, we focused on social context effects on USV production. We show that Shank1(-/-) pups vocalized less and displayed a delay in the typical inverted U-shaped developmental USV emission pattern with USV rates peaking on postnatal day (PND) 9, resulting in a prominent genotype difference on PND6. Moreover, testing under social conditions revealed even more prominently genotype-dependent deficits regardless of the familiarity of the social context. As communication by definition serves a social function, introducing a social component to the typically nonsocial test environment could therefore help to reveal communication deficits in mouse models for ASD. Together, these results indicate that SHANK1 is involved in acoustic communication across species, with genetic alterations in SHANK1 resulting in social communication/interaction deficits.

Objective: This study describes, from the perspective of parents, how females with Rett syndrome communicate in everyday life and the barriers and facilitators to successful communication., Methods: Sixteen interviews were conducted with parents with a daughter with Rett syndrome with a pathogenic mutation in the methyl-CpG-binding protein 2 gene. Interviews were recorded and transcribed verbatim. Transcripts were analysed using directed content analysis., Results: All parents reported their daughters were able to express discomfort and pleasure, and make requests and choices using a variety of modalities including vocalisations, body movements and eye gaze. Parents also reported their daughters understood most of what they said and that the level of functional abilities, such as mobility, and environmental factors, such as characteristics of the communication partner, influenced successful communication., Conclusions: The perspectives of parents are integral to the assessment of communication abilities and have the potential to inform communication interventions for girls and women with Rett syndrome.

Disruptions in speech, language, and vocal communication are hallmarks of several neuropsychiatric disorders, most notably autism spectrum disorders. Historically, the use of animal models to dissect molecular pathways and connect them to behavioral endophenotypes in cognitive disorders has proven to be an effective approach for developing and testing disease-relevant therapeutics. The unique aspects of human language compared with vocal behaviors in other animals make such an approach potentially more challenging. However, the study of vocal learning in species with analogous brain circuits to humans may provide entry points for understanding this human-specific phenotype and diseases. We review animal models of vocal learning and vocal communication and specifically link phenotypes of psychiatric disorders to relevant model systems. Evolutionary constraints in the organization of neural circuits and synaptic plasticity result in similarities in the brain mechanisms for vocal learning and vocal communication. Comparative approaches and careful consideration of the behavioral limitations among different animal models can provide critical avenues for dissecting the molecular pathways underlying cognitive disorders that disrupt speech, language, and vocal communication., (Copyright © 2016 Society of Biological Psychiatry.

Background: The ability to perform objective pain assessment is very important in paediatric patients. The goal of this study was to investigate the relationship between the analgesia nociception index (ANI), which is based on the heart rate variability, and objective measurements of pain intensity in young or cognitively impaired children, after surgical or imaging procedures (control group) under general anaesthesia., Methods: On arrival in the recovery room and subsequently at 5-10 min intervals, the level of pain was rated using the FLACC pain scale (0-10). The ANI values (0-100; 0 indicating the worst pain) were recorded simultaneously. The area under the receiver operating characteristic curve (AUC) and grey zone approach were used to evaluate the performance of the ANI to detect patients with FLACC >4. Instantaneous ANI values were compared with ANI values averaged over 256 s periods of time., Results: All children in the surgical group (n=32) developed moderate-to-severe pain (FLACC >4). Children in the control group (n=30) exhibited minimal pain. Instantaneous ANI values were lower in children of the surgical group than in the control group [52 (sd16) vs 69 (16), P<0.001]. The AUC for the 256 s ANI recording period [0.94 (95% confidence interval 0.85-0.99)] was significantly higher than for instantaneous ANI (P<0.05). When measured for a period of 256 s, an ANI cut-off value of 56 (grey zone [58-60]) was most predictive of a FLACC ≥4., Conclusions: The ANI may provide an objective measurement of acute postoperative pain, which is correlated with that measured on a FLACC scale in young or cognitively impaired children., (© The Author 2015.

Purpose: To verify age and education effects on communication performance of healthy adults in the Montreal Communication Evaluation Battery, Portuguese version (MAC-PT)., Methods: The sample comprised 90 healthy adults from Portugal, European Portuguese speakers, divided into nine groups according to educational level (4-9, 10-13, and > 13 years of formal schooling) and age (19-40, 41-64, and 65-80 years). The influence of age and education was assessed by comparing mean scores between groups, using a two-way analysis of variance followed by Bonferroni post hoc tests (p ≤ 0.05)., Results: The results showed that participants' performance was influenced by age in pragmatic-inferential, discursive, and prosodic tasks. Education had the greatest influence on the performance in all processes evaluated by the MAC-PT., Conclusion: Age and education seem to influence the communicative performance and should be considered in the assessment of neurological patients.
