Background: Although adding embodied instructors on the screen is considered an effective way to improve online multimedia learning, its effectiveness is still controversial. The level of realism of embodied on-screen instructors may be an influencing factor, but it is unclear how it affects multimedia learning. Aims: We explored whether and how embodied on-screen instructors rendered with different levels of realism in multimedia lessons affect learning process and learning outcomes. Samples: We recruited 125 college students as participants. Methods: Students learned about neural transmission in an online multimedia lesson that included a real human, cartoon human, cartoon animal or no instructor. Results: Students learning with cartoon human or cartoon animal instructors tended to fixate more on the relevant portions of the screen and performed better on retention and transfer tests than no instructor group. The real human group fixated more on the instructor, fixated less on the relevant portion of the screen and performed worse on a retention test in comparison to the cartoon human group. Fixation time on the instructor fully mediated the relationship between instructor realism and retention score. Conclusions: The addition of embodied on-screen instructors can promote multimedia learning, but the promotion effect would be better if the embodied instructor was a cartoon animal or cartoon human rather than a real human. This suggests an important boundary condition in which less realism of on-screen embodied instructors produces better learning processes and outcomes.

This cross-sectional study aimed to investigate developmental changes in the efficiency of sustained, selective, and divided attention in a group of children aged 6-12 years by means of a computerized test battery. Participants included 199 children (51% female, majority White) who had normal or corrected-to-normal vision and no history of either neurological or attention deficit disorders. The study was conducted in three different schools. We used a convenience sampling strategy; each age group was sampled from one of the schools and was represented by students selected from different (parallel) classes of the same grade level. The three aspects of attention showed different developmental trajectories from 6 to 12 years. In terms of accuracy, selective attention was found to improve gradually, while the efficiency of divided attention increased dramatically across the school-age years. In terms of reaction time, all attentional components showed a slow developmental time course. The results indicate that situations in which children have to divide attention among several sources of visual information while looking for two target stimuli considerably hamper their task performance. This is especially true for children of senior preschool and primary school age.

The limitation of conventional visual acuity assessment, which primarily focuses on individual eye performance (monocular visual acuity tests). This study addresses this limitation by emphasizing the importance of binocular vision, where both eyes work together. Binocular vision provides numerous advantages, such as improved depth perception, a wider field of view, reduced visual fatigue, and binocular summation. The article introduces a new mathematical model based on the physics of constructive interference in light waves and the anatomy of visual nerves. This model yields an equation that quantifies how weakness in one eye affects the visual acuity of the other. By analyzing the correlation between the rates of visual weakness in each eye and the corresponding distances, utilizing the Snellen 6-meter test, valuable insights are gained into the complex interplay between eye deficiencies and their collective impact on overall visual acuity. The equations derived from this study can have significant implications for eye care professionals, clinicians, and patients, contributing to a more comprehensive understanding of visual impairments and enriching the field of optics and vision science.

This study investigated the self-concept of students with vision impairments who were placed in mainstream and specialist schools in South Australia. Self-Concept was studied across six dimensions, namely Physical, Moral, Personal, Family, Social and Academic Self-Concepts and the Total Self-Concept. The 'Tennessee Self-Concept Scale: Second Edition' was administered to 25 students with vision impairments (including low vision and blind students) who attended mainstream or specialist schools. Although most of the students with vision impairments obtained low scores on all dimensions of self-concept, namely physical, moral, personal, family, social and academic, there were some students who attended specialist schools and are blind that obtained normal scores in family, social and academic self-concepts. There were no significant differences between students with vision impairments that attended mainstream or specialist schools and between students with low vision and those who are blind across the six dimensions of self-concept and thus total self-concept. These findings have implications for mainstream teachers, special educators, support staff and a range of professionals in the education and special education sector in enabling a greater understanding of the self-concept achievement of the students with vision impairments that attended mainstream or specialist schools.

Haptic perception is used in the anatomy laboratory with the handling of three-dimensional (3D) prosections, dissections, and synthetic models of anatomical structures. Vision-based spatial ability has been found to correlate with performance on tests of 3D anatomy knowledge in previous studies. The objective was to explore whether haptic-based spatial ability was correlated with vision-based spatial ability. Vision-based spatial ability was measured in a study group of 49 medical graduates with three separate tests: a redrawn Vandenberg and Kuse Mental Rotations Tests in two (MRT A) and three (MRT C) dimensions and a Surface Development Test (SDT). Haptic-based spatial ability was measured using 18 different objects constructed from 10 cubes glued together. Participants were asked to draw these objects from blind haptic perception, and drawings were scored by two independent judges. The maximum score was 24 for each of MRT A and MRT C, 60 for SDT, and 18 for the drawings. The drawing score based on haptic perception [median = 17 (lower quartile = 16, upper quartile = 18)] correlated with MRT A [14 (9, 17)], MRT C [9 (7, 12)] and SDT [44 (36, 52)] scores with a Spearman's rank correlation coefficient of 0.395 (p = 0.0049), 0.507 (p = 0.0002) and 0.606 (p < 0.0001), respectively. Spatial abilities assessed by vision-based tests were correlated with a drawing score based on haptic perception of objects. Future research should investigate the contribution of haptic-based and vision-based spatial abilities on learning 3D anatomy from physical models.

Mask wearing has been required in various settings since the outbreak of COVID-19, and research has shown that identity judgements are difficult for faces wearing masks. To date, however, the majority of experiments on face identification with masked faces tested humans and computer algorithms using images with superimposed masks rather than images of people wearing real face coverings. In three experiments we test humans (control participants and super-recognisers) and algorithms with images showing different types of face coverings. In all experiments we tested matching concealed or unconcealed faces to an unconcealed reference image, and we found a consistent decrease in face matching accuracy with masked compared to unconcealed faces. In Experiment 1, typical human observers were most accurate at face matching with unconcealed images, and poorer for three different types of superimposed mask conditions. In Experiment 2, we tested both typical observers and super-recognisers with superimposed and real face masks, and found that performance was poorer for real compared to superimposed masks. The same pattern was observed in Experiment 3 with algorithms. Our results highlight the importance of testing both humans and algorithms with real face masks, as using only superimposed masks may underestimate their detrimental effect on face identification.

It is commonly accepted that repeatedly using mental procedures results in a transition to memory retrieval, but the determinant of this process is still unclear. In a 3-week experiment, we compared two different learning situations involving basic additions, one based on counting and the other based on arithmetic fact memorization. Two groups of participants learned to verify additions such as "G + 2 = Q?" built on an artificial sequence (e.g., "XGRQD…"). The first group learned the sequence beforehand and could therefore count to solve the problems, whereas the second group was not aware of the sequence and had to learn the equations by rote. With practice, solution times of both groups reached a plateau, indicating a certain level of automatization. However, a more fine-grained comparison indicated that participants relied on fundamentally different learning mechanisms. In the counting condition, most participants showed a persistent linear effect of the numerical operand on solution times, suggesting that fluency was reached through an acceleration of counting procedures. However, some participants began memorizing the problems involving the largest addends: Their solution times were very similar to those of participants in the rote learning group, suggesting that they resulted from a memory retrieval process. These findings show that repeated mental procedures do not systematically lead to memory retrieval but that fluency can also be reached through the acceleration of these procedures. Moreover, these results challenge associationist models, which cannot currently predict that the process of memorization begins with problems involving the largest addends.

According to current accounts of social cognition, the emergence of verbal and non-verbal components of social perception might rely on the acquisition of different cognitive abilities. These components might be differently sensitive to the pattern of neuropsychological impairments in congenital neurodevelopmental disorders. Here, we explored the association between social and non-social cognitive domains by administering subtests of the NEPSY-II battery to 92 patients with Intellectual and Developmental Disability (IDD). Regardless the level of intellectual functioning and presence of congenital brain malformations, results revealed that visuospatial skills predicted emotion recognition and verbal component of Theory of Mind, whereas imitation predicted the non-verbal one. Future interventions might focus on spatial and sensorimotor abilities to boost the development of social cognition in IDD.

The Cattell-Horn-Carroll (CHC) or three-stratum model of intelligence envisions human intelligence as a hierarchy. General intelligence (g) is situated at the top, under which are a group of broad intelligences such as verbal, visuospatial processing, and quantitative knowledge that pertain to more specific areas of reasoning. Some broad intelligences are people-centered, including personal, emotional, and social intelligences; others concern reasoning about things more generally, such as visuospatial and quantitative knowledge. In the present research, we conducted a meta-analysis of 87 studies, including 2322 effect sizes, to examine the average correlation between people-to-people intelligences relative to the average correlation between people-to-thing-centered intelligences (and similar comparisons). Results clearly support the psychometric distinction between people-centered and thing-centered mental abilities. Coupled with evidence for incremental predictions from people-centered intelligences, our findings provide a secure foundation for continued research focused on people-centered mental abilities.

Binocular disparity provides one of the important depth cues within stereoscopic three-dimensional (3D) visualization technology. However, there is limited research on its effect on learning within a 3D augmented reality (AR) environment. This study evaluated the effect of binocular disparity on the acquisition of anatomical knowledge and perceived cognitive load in relation to visual-spatial abilities. In a double-center randomized controlled trial, first-year (bio)medical undergraduates studied lower extremity anatomy in an interactive 3D AR environment either with a stereoscopic 3D view (n = 32) or monoscopic 3D view (n = 34). Visual-spatial abilities were tested with a mental rotation test. Anatomical knowledge was assessed by a validated 30-item written test and 30-item specimen test. Cognitive load was measured by the NASA-TLX questionnaire. Students in the stereoscopic 3D and monoscopic 3D groups performed equally well in terms of percentage correct answers (written test: 47.9 ± 15.8 vs. 49.1 ± 18.3; P = 0.635; specimen test: 43.0 ± 17.9 vs. 46.3 ± 15.1; P = 0.429), and perceived cognitive load scores (6.2 ± 1.0 vs. 6.2 ± 1.3; P = 0.992). Regardless of intervention, visual-spatial abilities were positively associated with the specimen test scores ([eta squared] = 0.13, P = 0.003), perceived representativeness of the anatomy test questions (P = 0.010) and subjective improvement in anatomy knowledge (P < 0.001). In conclusion, binocular disparity does not improve learning anatomy. Motion parallax should be considered as another important depth cue that contributes to depth perception during learning in a stereoscopic 3D AR environment.

This study investigated whether increased attention to the central or peripheral visual field can reduce motion sickness in virtual reality (VR). A recent study found that increased attention to the periphery during vection was correlated with lower self-reported motion sickness susceptibility, which suggests that peripheral attention might be beneficial for avoiding cybersickness. We tested this experimentally by manipulating visual attention to central vs. peripheral fields during VR exposure. We also measured attention to the periphery during vection and motion sickness susceptibility to attempt to replicate the previous results. In Experiment 1, task-relevant cues to target locations were provided in the central or peripheral field during navigation in VR, and we found no differences in motion sickness. In Experiment 2, attention to the center or periphery was manipulated with a dot-probe task during passive VR exposure, and we found that motion sickness was greater in the condition that required attention to the periphery. In both experiments, there was no correlation between baseline attentional allocation and self-reported motion sickness susceptibility. Our results demonstrate that restricting attention to the central visual field can decrease cybersickness, which is consistent with previous findings that cybersickness is greater with large FOV.

Visual acuity significantly contributes to quality of life. Deficits in childhood are associated with reading difficulties, which can have detrimental effects on education outcomes. In adults, it has been observed that vision defects such as myopia are associated with higher educational attainment (EA). Understanding genetic factors contributing to visual acuity could help to dissect its links with cognitive skills, neurodevelopmental conditions, and education. We examined associations between distance visual acuity, cognitive measures including school grades, and neurodevelopmental conditions in a longitudinal cohort of British children (ALSPAC, n = 6807, M age = 11.8). We performed a genome-wide association study (GWAS, n = 5571) on visual acuity and tested for genetic associations with relevant phenotypes using polygenic scores (PGS) and genetic correlation analyses. Visual acuity was associated with better cognitive performance and school grades, and reduced in individuals with reading difficulties compared to controls. GWAS revealed genetic associations at the "NPLOC4" locus and highlighted other genes involved in sensory function. In line with positive genetic correlations between visual acuity and cognitive measures, EA PGS were positively associated with visual acuity, while there was a less robust negative association with myopia PGS. In conclusion, increased visual acuity is associated with a range of positive outcomes, including better school grades. Our results suggest an association between a higher EA PGS and slightly increased visual acuity in childhood. This could indicate gene-environment correlation, in which environmental exposures linked to higher EA might have detrimental effects on vision offsetting the initial positive effect.

Motor skills have been linked to language and social development with implications for theory of mind. This study examined theory of mind (attribution of intentions task) in school-age children (N = 62, mean age 8 years; 2 months, standard deviation [SD] = 1;3) in relation to fine motor skills (grooved pegboard), receptive vocabulary (Peabody Picture Vocabulary Test), receptive grammar (Test for the Reception of Grammar), reading comprehension (Woodcock Reading Mastery Tests), verbal short-term (nonword repetition), and visual-spatial working memory (one-shape array memory). All variables except verbal short-term memory correlated with accuracy on theory of mind. In regression models, fine motor skills accounted for variance in theory of mind after controlling for age, language, and working memory. The results add to research linking fine motor skills with faux pas understanding, indicating the potentially broad impact of motor skills on social cognition. Given the cross-sectional study design, longitudinal research is warranted to address causality.

The purpose of the present research is to develop a visual-spatial ability test (VSAT) for primary school children. Visual-spatial abilities allow processing of information about an object in terms of shape, colour, texture, perspective, and rotation. The visual-spatial test includes items-tasks for the participants to process information about texture, colour, shape and perspective. A total of 196 primary school children participated in the research. The data were analysed through Rasch analysis and item-response theory. Findings proved that VSAT yields reliable and valid results for assessing the visual-spatial ability of primary school children.

This study was conducted with the aim of determining self efficacy-sufficiency levels of visually impaired individuals according to some variables. Bandura (1994) states that self-sufficiency, defined as an individual's belief on operating a specific job, is an important factor for the athletes. Self-sufficiency results in choosing a field of study voluntarily, feeling a high motivation for accomplishing that job, endeavoring and spending time on the study. Self-sufficiency is about the individual's specific area or behavior group (Akkoyunlu & Orhan, 2003). The study was conducted on 127 male and 60 female visually-impaired individuals, a total of 187, with different visual acuity in different visually-handicapped clubs. The voluntary basis was taken into consideration in participation. As the data collection tool, "Personal Information Form" and "Self-Efficacy--Sufficiency Scale" which was developed by Sherer et al. (1982), and adopted into Turkish by Gözüm and Aksayan (1999). The data set was analyzed in SPSS 20.0 packaged programme. The data was purified from loss and wrong coding, and the normality hypothesis was done with kurtosis and skewness values. In the analysis of the data, frequency, the average standard deviation was used; besides, T-Test (in paired comparisons) gender, disability status, marital status and branches of sports; one-way variance (ANOVA) test in age, level of education, level of income and visual acuity were used. When one-way ANOVA results of self-sufficiency scores according to gender, age, disability status, level of education, level of income, and visual acuity were analyzed, it was stated that there was a significant difference (p<0,05), and there is no significant difference in Self-Sufficiency scores of visually-impaired individuals who are doing team and individual sports (p>0,05). When evaluated the information above, it can be said that like self efficacy-sufficiency concept can be in different levels and different dimension in different areas of life; it is effective on visually-impaired individuals. In this respect, it is considered that this study will open a new window to this area and contribute to the visually-impaired athletes. Besides, it is suggested that a new study on how self efficacy-sufficiency concept is in the visually-impaired athletes and other individuals, and evaluation of how they are affected. In this concept, the general aim of this study is to analyze the levels of self efficacy-sufficiency of visually-impaired athletes.

This paper investigates the potential aspects of visual literacy that might appear when visual analytics and students interact in social science secondary classrooms. Interacting with visual technology likely demands new forms of literacy as various dimensions of complexity emerge in such learning activities where reading imposes order and relevance on what is displayed. However, only a few studies have evaluated how these visual processes emerge. Applying a socio-material semiotic approach, this paper examines the interactions between teachers, students and a visual analytics application, clarifying what strengthens or weakens the socio-material relations at work in emerging visual literacy. Methodologically, a designbased research approach is chosen. Notably, it is the early stages of the designed-based research cycle that are applied. Interventions were designed and conducted in five classes in three secondary schools in Sweden (97 students). The visual analytics application introduced was Statistics eXplorer. For each class, two to three lessons were video recorded to capture how the students interacted with the application. The socio-material analyses show that the interactions between the visual analytics and the students were both strengthened and weakened by different social as well as material forces. The actions were directed by visual properties such as movement, highlighting, and color, properties that often resulted in quick vision or locked vision. This paper argues that there needs to be a close didactic alignment and deeper knowledge of how visual interfaces attract students' attention and how students' visual literacy emerges in that relationship.

Introduction: The readability of prescription drug labels has been found to be faster with labels attached to flat surfaces compared to round surfaces, in persons with visual impairment. This study extends this finding by examining the readability of drug labels, as measured by speed and accuracy, as they interact with factors of age and vision acuity across different container shapes. Methods: A repeated-measure, three-factor design (container shape, age, and vision acuity) with within-subject control was used with 54 adults with vision loss. Participants read 3 unique prescription drug labels across four container shapes, for a total of 12 trials. The amount of time needed to locate and read aloud 6 pieces of label information and the number of errors made in reading were outcome measures. Results: A two-way interaction was found between container shape and acuity for the time it takes to read the label information (Wald X[superscript 2] = 22.836, df = 3, p < 0.001). The legally blind group required more time to read the label and had more variation in mean times across container type, compared to the low vision group. Both age and acuity showed statistically significant (p < 0.001) main effects on reading accuracy. Discussion: Within the legally blind acuity group, cylinder-shaped containers took statistically significantly longer to read compared to the flat label by 18 seconds. Increased age and lower visual acuity negatively affected reading accuracy, across all container shapes. Implications for Practitioners: Individuals with legal blindness may need more time to read prescription drug labels and may benefit from labels adhered to flat surfaces over traditional cylindrical containers. As medication safety is a critical skill for independent living, practitioners should assess their clients' ability to access prescription drug label information, keeping in mind that these abilities may differ across different container shapes.

This study explored the association between children's vision and their school academic progress as reported by parents/guardians. Participants were 1,612 schoolchildren (722 6-7-year-olds, 890 12-13-year-olds) in randomly selected schools in Ireland. In advance of data collection, parents/guardians reported school performance as (a) much better than classmates (high-performance) (b) about the same as classmates (average-performance) (c) not as well as classmates (low-performance). Measurements included logMAR monocular visual acuities (with spectacles if worn, and pinhole) in the distance (3 m) and near (40 cm); the amplitude of accommodation; stereoacuity, colour vision assessment, and cyclopleged autorefraction. Controlling for confounders, children presenting with visual impairment (vision poorer than 0.3logMAR (6/12) in the 'better eye'), amblyopia ('lazy eye'), uncorrected refractive error (hyperopia [greater than or equal to]+3.50D and astigmatism [greater than or equal to]1.50DC), reduced for age ability to adjust focus from distance to near tasks (accommodation), impaired three-dimensional vision (stereoacuity), and defective colour vision were more likely to report low-performance in school. The majority of low-performing participants (68%) did not have an eye examination within the 12 months before data collection. Children with academic performance challenges ought to have a comprehensive eye examination, to detect potential vision problems for early intervention minimising any negative impact they may have on educational outcomes.

Introduction: Pediatric cataract is still a major cause for childhood visual impairment. The goal of our study was to analyze the prevalence of children with impaired vision (6/15 or worse) after surgery for bilateral cataract, to evaluate factors associated with it and to emphasize the importance for visual rehabilitation including the use of visual aids, educational measures, and social worker services. Methods: Retrospective analysis of medical records from children who underwent surgery for cataract up to age 6 years, with a follow-up of at least 4 years. Clinical characteristics retrieved from medical records included visual acuity, presence of nystagmus and/or strabismus, age at surgery, intraocular lens (IOL) implantation, and others. Results: Fifty-five children were included in the study. Follow-up ranged from 4 to 13 years (Mdn = 6.8). Visual impairment was found in 15/24 (62.5%) of children operated on before the age of 6 months (group 1), and in 7/31 (22.5%) n those operated after the age of 6 months (group 2; p = 0.019). Thirty-eight of the 55 children had a primary IOL implantation; nystagmus and microphthalmos were also associated with higher rates of visual impairment. Discussion: Despite early and modern surgery, long-term visual outcome remains poor in children undergoing bilateral cataract surgery at young age. When discussing visual prognosis with parents, it is important to recognize factors associated with visual impairment, such as need for surgery before age 6 months, nystagmus and microphthalmos, as well as the importance for early visual rehabilitation services when needed.

The National Eye Institute (2015) reports that by the year 2050, the number of individuals with age-related macular degeneration (AMD) will rise from 2.07 million to 5.44 million. AMD causes central vision loss, which can affect independence in activities such as medication management, meal preparation, and personal finances (Smallfield, Clem & Myers, 2013). Most of these activities require reading, making an inability to read a concern for those with AMD (Hassell, Lamoureaux, & Keeffe, 2006). Font size and style of text may improve reading performance for individuals with low vision. Most recommendations addressing font styles are not evidence based. The aim of this mixed-methods study was to determine the preferred font style of individuals with AMD, and whether a sans-serif, proportionally-spaced font (Arial) or a serif, mono-spaced font (Courier New) improved reading performance for individuals with AMD.

Introduction: The purpose of this study was to gain information from parents in the United States about their children with albinism. The article focuses on information and services related to medical care and low vision care. Methods: An online questionnaire was used to collect data, and parents had opportunities to submit additional information. One hundred ninety-two families, representing 223 children with albinism from 40 U.S. states, completed surveys. Results: A snapshot of the data indicates that for 8.6 out of 10 families, there were no known relatives with the condition; 55.8% of the children had visual acuities that met the criteria for legal blindness in the United States; and 48% of the children using optical devices had received clinical low vision evaluations by optometrists or ophthalmologists who specialized in low vision. Implications for practitioners: The data gathered suggest recommendations for medical service providers, including clinical low vision specialists who perform evaluations for improving the functional use of vision.

Past research has demonstrated that the hierarchical value structures of creative individuals differ systematically from their less creative counterparts. However, earlier studies used a global creativity score, which is inconsistent with both creativity's movement toward a domain-specific viewpoint, and Lebedeva et al.'s 2019 study suggests the relationship between values and the frequency of creative behaviors differs by domain. We conducted two studies to determine if different creative domains are associated with distinct value hierarchies in creative ability, self-perception, and achievement. Study 1 (N = 156) examined whether Schwartz's core values demonstrated a different pattern of correlations with verbal versus visual creative performance, assessed with story and drawing tasks. Study 2 (N = 492) examined the pattern of values across a broader set of domains (i.e., artistic, everyday/self, science, performance, and scholarly), assessed using measures of creative self-concept and self-reported creative achievement. The value hierarchies associated with each of the domains were not consistent with each other or with the findings of past studies. The implications of these results for creative domain specificity and motivation are discussed.

This article introduces this special issue of "Frontline Learning Research." The first paper offers a methodological guide using Ericsson & Smith's (1991) "expert performance approach." This is followed by three papers that analyze the use of eye tracking in visual expertise models, and a paper reviewing the use of methods such as EEG and fMRI to investigate the neural correlates of visual perceptual expertise. A paper on Receiver Operating Characteristic (ROC) analysis brings new insight to the well-known signal detection methods used in control and visual inspection tasks in industry. Finally, three papers review methods based on verbal reports and protocols used to investigate the conceptual and meta-cognitive levels of visual expertise. The following sections (1) describe the methodological contribution of each paper according to five main themes or criteria and (2) discuss the benefits, limitations, and particularly the opportunities offered by new developments in each methodology and their possible combinations.

Introduction: This study analyzed survey responses from 314 teachers of students with visual impairments regarding the tools and procedures used in completing functional vision assessments (FVAs). Methods: Teachers of students with visual impairments in the United States and Canada completed an online survey during spring 2016. Results: The majority of participants reported that they primarily assess pre-academic and academic students in kindergarten through 12th grade (K-12). More than 95% of all participants indicated that they assess near and distance visual acuity. Other commonly assessed skills and abilities were tracking (n = 298; 95%), peripheral visual fields (n = 296; 94%), and color perception (n = 293; 93%). Approximately 50% of survey participants indicated that they use a screening tool in determining the need for an orientation and mobility (O&M) evaluation. Discussion: The procedures and tools used by participants in completing FVAs varied based on the specific student being assessed. There was also considerable variation in visual skills assessed, as well as in what was included in the assessment report by the participants. Based on comments from participants, it appears that there are complex factors that influence the decision-making process regarding possible referrals for an O&M evaluation or a clinical low vision evaluation. Implications for practitioners: Teachers should reflect on their own practices and procedures to determine whether they are including all pertinent information in their FVA reports, as well as explore whether they should assess additional visual skills in order to provide a rich description of how the student uses his or her vision throughout the day in a variety of environments.

Passages with continuous sentences are commonly used for the assessment of reading performance related to visual function, and rehabilitation in optometric practices. Passages created in native languages are crucial for a reliable interpretation in a real scenario. This study aimed to report the development of SAH Reading Passage Compendium (SAHRPC), as a tool for the assessment of reading performance related to visual function. SAHRPC uses the Malay language as the medium of communication. The development of the SAHRPC encompassed three stages: exploratory, confirmatory and prototyping. In the exploratory stage, 300 sentences were extracted from the standard school textbook (in the Malay language) endorsed by the Ministry of Education, Malaysia. The accumulated reading materials were processed based on two deciding factors: continuous sentence structure and predetermined total number of words. A total of 56 passages were constructed with equal readability, based on a simple "5 continuous sentences structure of 50 words" combination. In the confirmatory stage, the 56 passages were verified by normal sighted native Malay speakers. The reading duration was measured using a stopwatch, while the errors were recorded using an audiotape. Reading speed was quantified in words per minute (wpm). Three passages were first eliminated based on the outliers present in the boxplot graph. Eleven passages were further eliminated based on the 10 % highest error and 5 % of the two extreme ends of the reading speed range. The remaining 42 passages with good reliability were randomly compiled into 3 sets of 13 passages. Thirteen passages in each set were randomly sorted into 13 print sizes, ranged from 1.2 logMAR to 0.0 logMAR. The interchangeability of the 3 sets was inspected and confirmed. A prototype was developed and packaged as the SAHRPC, to be used as a tool for the assessment of reading performance related to visual function, and rehabilitation purposes.

Functional neuroimaging is a useful approach to study the neural correlates of visual perceptual expertise. The purpose of this paper is to review the functional-neuroimaging methods that have been implemented in previous research in this context. First, we will discuss research questions typically addressed in visual expertise research. Second, we will describe which kinds of stimuli are employed and which functional-neuroimaging techniques are implemented in this kind of research, with a special focus on electroencephalography (EEG) and functional magnetic resonance imaging (fMRI). Third, we will summarize the outcomes of recent studies that addressed the neural correlates of visual expertise and will particularly focus on studies that examined the neural correlates of visual expertise in medical image diagnosis. Finally, the review closes with a discussion of the benefits, caveats, and future directions of cognitive-neuroscience research for studying visual expertise.

Eye-tracking is the measurement of eye motions and point of gaze of a viewer. Advances in this technology have been essential to our understanding of many forms of visual learning, including the development of visual expertise. In recent years, these studies have been extended to the medical professions, where eye-tracking technology has helped us to understand acquired visual expertise, as well as the importance of visual training in various medical specialties. Medical decision-making involves a complex interplay between knowledge and sensory information, and the study of eye-movements can reveal the mechanisms involved in acquiring the visual component of these skills. Eye-tracking studies have even been extended to develop computational models of procedures for "expert" skill assessment, and to eliminate potential sources of error in image-based diagnostics. This review will examine the current eye-tracking frontier for the study of visual expertise, with specific application to medical professions.

This study looks at the practice of thoracic radiology and follows a group of radiologists and radiophysicists in their efforts to find, discuss, and formulate issues or troubles ensuing the implementation of a new radiographic imaging technology. Based in the theoretical tradition of ethnomethodology it examines the local endogenous practices pertaining to the radiologists' expertise in the interpretation of visual representations and tries to explicate the ways in which they draw upon various resources in order to accomplish their professional tasks. As the study is addressing the topic of visual expertise it also aims to do so in terms that acknowledge that all expertise is rooted in embodied practices. The analysis follows a case of what is called the enacted production of radiological reasoning. One of the central features of the described work is the manner in which it is carried out by way of the living present body of an expert. The experienced radiologist interweaves anatomical and technological terminology with visual representations and gestures in such a way that none of these components can be said to be superfluous to the argumentation. As a consequence, we should appreciate gestures and embodied actions as important means through which expertise become organised. These are parts of a repertoire of methods through which the experts learn their profession. In addition, gestures can also become enrolled in the re-negotiation of expertise in the face of new challenges.

Introduction: In addition to optical devices, closed-circuit televisions (CCTVs) and eccentric viewing training are both recognized interventions to improve reading performance in individuals with vision loss secondary to age-related macular degeneration. Both are relatively expensive, however, either in the cost of the device or in the amount of time personnel need to provide training. In this randomized trial, we compared the effectiveness of these two interventions. Methods: Participants with age-related macular degeneration and visual acuity between 6/48 (20/160) and 6/120 (20/400) first received basic low vision care, including optical devices. At the subsequent baseline visit, they undertook a battery of measures including logMAR visual acuity; reading speed and accuracy for text in 1.3M and 1M fonts; reading information on medicine bottles, utility bills, and food packages; the NEI-VFQ; the Geriatric Depression Scale; and a reading inventory questionnaire. They were then randomized to either obtaining a CCTV for home use or eccentric viewing training over the following six weeks. Results: Recruitment was more difficult than expected for this population. Of 145 patients referred, 29 met the inclusion-exclusion criteria, 14 were willing to enroll, and 10 completed the trial. For the primary outcome (reading speed for 1.3M print), there was a significant improvement between baseline and outcome for the CCTV group (p 0.005), but not for the eccentric viewing training group (p 0.28), and the CCTV group showed significantly greater change (p 0.04). There was a nonsignificant improvement in reading speed for 1M text and a decrease in the amount of time taken to read utility bill information in the CCTV group. There was a significant improvement in near visual acuity with current glasses with eccentric viewing training. The other measures did not reach statistical significance. Discussion: Randomized clinical trials for low vision rehabilitation, particularly in the elderly population with vision loss, are challenging, but such trials are important for the allocation of resources. This trial showed early indications of more impact on reading performance from CCTV than eccentric viewing training.

This paper reports on a case study of two elementary school students with mathematical learning disabilities (MLD) (ages 10 and 11) using augmented reality (AR), digital and physical modelling in mathematics class. MLD students worked on modelling geometric shapes (cubes, cuboids, squared pyramids, and octahedrons) and forms (polygons) by combining real-world objects with AR and creating a copy of geometric shapes or missing parts with a 3D printing device. The study focused on the development of process skills and mathematical concepts, tried to identify changes in the visual-spatial memory, and documented the learning behaviour in class. Further, we collected data through task-based interviews with both students. Based on our findings, we present settings and manipulatives which are likely to foster process skills and mathematical concepts in geometry tasks suitable for MLD elementary school students.

Finding an unfamiliar person in a crowd of others is an integral task for police officers, CCTV-operators, and security staff who may be looking for a suspect or missing person; however, research suggests that it is difficult and accuracy in such tasks is low. In two real-world visual-search experiments, we examined whether being provided with four images versus one image of an unfamiliar target person would help improve accuracy when searching for that person through video footage. In Experiment 1, videos were taken from above and at a distance to simulate CCTV, and images of the target showed their face and torso. In Experiment 2, videos were taken from approximately shoulder height, such as one would expect from body-camera or mobile phone recordings, and target images included only the face. Our findings suggest that having four images as exemplars leads to higher accuracy in the visual search tasks, but this only reached significance in Experiment 2. There also appears to be a conservative bias whereby participants are more likely to respond that the target is not in the video when presented with only one image as opposed to 4. These results point to there being an advantage for providing multiple images of targets for use in video visual-search.

Introduction: This study analyzed 39 data collection tools used by teachers of students with visual impairments when completing functional vision assessments (FVAs). Methods: In 2017, teachers of students with visual impairments submitted data collection tools used in the FVA process. These tools were then compared with the 23 FVA components suggested by two established resources, Erin and Paul and D'Andrea and Farrenkopf. Results: The most commonly assessed skills and abilities were near visual acuity, distance visual acuity, and color perception. Only five of the submitted data collection tools contained at least 80% of the FVA components identified by the established resources. Fewer than 25% of the tools incorporated an orientation and mobility (O&M) screening. Discussion: There was considerable variation in the background information, medical data, and visual skills information that was collected. Variability in the data collected during the FVA process may impact a teacher's recommendations, including referrals for specialized evaluations such as O&M and clinical low vision evaluations. Implications for practitioners: Since FVA reports are used by Individualized Education Program teams, it is essential that data collection tools used during the assessment process are complete and address key areas such as near visual acuity and color perception. Teachers should carefully review their tools to determine whether the data collected are sufficient to make informed recommendations regarding accommodations, goals, and referrals. If the data collected are not sufficient, then the tools should be revised or additional data should be collected.

Decision making, a complex mental activity underlying the act of choosing from among the alternatives in attaining a goal constitutes the core component of planning, a higher order cognitive process as per the PASS theory of intelligence. An attempt, therefore, has been made in the present study to examine the development of planning behaviour in children with increasing age and grade. Marker tests of planning were administered to a group of 60 children, 20 each from Grades Three, Five and seven in order to see the group difference among them in respect of planning at its various levels. Results revealed age and grade related changes in the development of planning behavior at lower levels, but not at higher level. The findings have been discussed in terms of developmental changes in children in cognitive functioning with regard to planning and consequences of formal schooling and suggestions have been made for the improvement of the planning skill through remedial training.

Introduction: This study characterizes self-reported functional vision goals and the use of low vision resources (for example, services and devices) in ophthalmology clinic patients with age-related macular degeneration (AMD) and comorbid depressive symptoms. Methods: From July 2009 to February 2013, we assessed 188 consecutive patients (age 65+; mean 84.0 years; 70.2% female) with AMD (best corrected distance acuity 20/70 or worse) enrolled in a 12-month randomized clinical trial to test the efficacy of a multicomponent intervention that combined low vision optometry and home-based occupational therapy to prevent depression (Low Vision Depression Prevention Trial [VITAL]). A geriatric nurse conducted in-home assessments to measure visual acuity and contrast sensitivity, self-reported functional vision, functional vision goals that were personally important yet difficult to achieve (targeted vision function goals), and the use of low vision resources (defined as services, devices and strategies utilized by low vision patients to compensate for visual deficits). This study reports on baseline data collected prior to randomization. Results: Only 9.6% of the sample had received formal low vision services. The five most common goals were newspaper reading, leisure and entertainment, computer use, personal communication, and correspondence. Participants engaged in targeted vision function goals less frequently since being diagnosed with AMD, despite using low vision resources and reporting low to moderate difficulty in using them. Discussion: Few patients with AMD seen in ophthalmology clinics received low vision rehabilitation. Patients who utilized resources engaged in goals less frequently since being diagnosed with AMD. Implications for practitioners: Patients with AMD are underutilizing low vision rehabilitation resources. Strategies for increasing low vision referrals are suggested.

Turner and Sheckles (2015) explain that communication centers are centered on campus and impact students' relationships with career and community opportunities (p. xii). This point is apparent in the centers' relationships with departments in addition to the career-development of student communicators. This article situates the communication center at the intersection of experiences developed through an intensive, embedded collaborative effort to enhance the communication-design process and experience for students. The unit activity described in this article challenged students to engage a full communication-design process through a collaborative partnership between the class and the communication center that tasked students to create their online, professional presence through an ePortfolio. The experience incorporated a series of workshops designed to provide students with the background and planning skills that contribute to the design of an effective professional online persona. Guided by the previous research of Carpenter, Apostel, & Hyndman (2012) as they examined the process of embedding workshops for ePortfolio design in communication-intensive courses, this unit activity focuses on enhancing the visual, written, and oral communication skills of students in the Communication, Leadership, and Change course at a regional comprehensive university.

Vision plays a key role in a child's development. Early detection and treatment of vision abnormalities decreases future complications. Follow-up vision care is a common problem. Barriers to vision care include financial cost, lack of insurance knowledge to cover costs, and disbelief of vision results. The purpose of this evidence-based pilot project was to improve the rate of follow-up vision care obtained by school-aged children. The target population was school-aged children from kindergarten to fifth grade at an elementary school within Lake County, Ohio. The vision referral program included phone calls to families to identify and overcome barriers to obtaining vision care. Barriers identified with the target population include disbelief of vision results, lack of knowledge about vision health, and financial cost. Results indicated an increase of vision care rates during the 2017-2018 academic year by 60% above baseline rates from the previous academic year.

Optometric disorders are likely to increase the difficulties experienced by an individual who is struggling to read. There are some reports of a higher incidence of visual abnormalities in children with dyslexia, but there has been little investigation into adults. We therefore investigated the optometric status of a population comprising children and adults with dyslexia. Fifty-four patients (27 with dyslexia, 27 controls) underwent extensive optometric testing. Measurements included visual acuity, cycloplegic refraction, accommodation, and binocular vision testing. There was a higher proportion of individuals with dyslexia presenting with optometric problems compared to controls. For children, the most common diagnoses were hypermetropia and accommodation insufficiency. The results strongly suggest that an optometric examination should be included in the management of dyslexia.

Visual-spatial abilities are considered a successful predictor in anatomy learning. Previous research suggest that visual-spatial abilities can be trained, and the magnitude of improvement can be affected by initial levels of spatial skills. This case-control study aimed to evaluate (1) the impact of an extra-curricular anatomy dissection course on visual-spatial abilities of medical undergraduates and (2) the magnitude of improvement in students with initially lower levels of visual-spatial abilities, and (3) whether the choice for the course was related to visual-spatial abilities. Course participants (n = 45) and controls (n = 65) were first and second-year medical undergraduates who performed a Mental Rotations Test (MRT) before and 10 weeks after the course. At baseline, there was no significant difference in MRT scores between course participants and controls. At the end of the course, participants achieved a greater improvement than controls (first-year: [Delta]6.0 ± 4.1 vs. [Delta]4.9 ± 3.2; ANCOVA, "P" = 0.019, Cohen's "d" = 0.41; second-year: [Delta]6.5 ± 3.3 vs. [Delta]6.1 ± 4.0; "P" = 0.03, Cohen's "d" = 0.11). Individuals with initially lower scores on the MRT pretest showed the largest improvement ([Delta]8.4 ± 2.3 vs. [Delta]6.8 ± 2.8; "P" = 0.011, Cohen's "d" = 0.61). In summary, (1) an anatomy dissection course improved visual-spatial abilities of medical undergraduates; (2) a substantial improvement was observed in individuals with initially lower scores on the visual-spatial abilities test indicating a different trajectory of improvement; (3) students' preferences for attending extracurricular anatomy dissection course was not driven by visual-spatial abilities.

The visual acuity of the eyes varies outside the range of normal vision, requiring corrective lenses, but also within the normal range. This study investigated whether both types of variation relate to individual differences in face-identity matching, considering this applied task requires perception of detail. Across two experiments, face-matching accuracy correlated with variation in acuity when this fell outside the normal range of vision and was uncorrected with glasses or contact lenses. In contrast, variation in visual acuity within the normal range did not affect face-matching accuracy, whereas matching accuracy at a given level of acuity could vary substantially. These results indicate that visual acuity is only a problem for occupations performing face-identity matching when below-normal acuity is not diagnosed or adequately corrected. In turn, these findings suggest that variation in acuity within the normal range is not a contributing factor to individual differences in face matching accuracy.

The vision plays an important role in educational technologies because it can produce and communicate quite important functions in teaching and learning. In this paper, learners' preference for the visual complexity on small screens of mobile computers is studied by neural networks. The visual complexity in this study is divided into five levels, including "very high" complexity, "slightly high" complexity, "medium" complexity, "slightly low" complexity and "very low" complexity. This study focuses on the age effects for vision problems in educational technologies. The age of the tested subjects distributes from 10 to 64, and is uniformly divided into 11 groups with each group composed of 30 tested subjects. For simplicity, the effects of gender, words, colors, and other visual factors are ignored. This study found that only learners of the younger and older age groups have special preference on the picture of very high complexity. Most learners prefer pictures of medium and slightly high complexity. These results are consistent with many existing studies. With the use of neural networks, only about half of the investigation data are required to predict the overall investigation results. Discussions and interpretations on the results are also given in this study. This study will be helpful in vision problems of educational technologies.

The world's population is aging at an increasing rate. Even in the absence of neurodegenerative disorders, healthy aging affects perception and cognition. In the context of cognition, common factors are well established. Much less is known about common factors for vision. Here, we tested 92 healthy older and 104 healthy younger participants in 19 visual tests (including visual search and contrast sensitivity) and three cognitive tests (including verbal fluency and digit span). Unsurprisingly, younger participants performed better than older participants in almost all tests. Surprisingly, however, the performance of older participants was mostly uncorrelated between visual tests, and we found no evidence for a common factor.

Professional vision is a key skill in visually-oriented professions, but its relevance to vocational education and training has only drawn limited attention from researchers. When educating fashion designers, professional vision is vital because precisely analysing clothing is required to create good products suitable for customers. In this study, we investigate what visual information must be observed in fashion design and how the professional vision of teachers and learners differs. Semi-structured interviews targeting the visual information that should be observed in fashion design were conducted with 10 teachers and 71 of their students (the latter in groups) and subjected to content analysis. Additionally, a test involving identifying and correcting clothing defects was administered to 9 of these teachers and 132 learners across three years of training to examine how looking at clothing differs between teachers and learners. Finally, two [4 by 1] ANOVAs with the level of training as the between-groups factors were conducted to examine the differences in the total number of defects identified and the number of accurate corrections suggested. Together, the quantitative and qualitative data show that professional vision in fashion design is a multifaceted skill that takes time to develop. Professional vision enables identifying the 1) different details and patterns needed to reproduce a garment; 2) defects in manufacturing, quality, and wearability; and 3) characteristics of the customer's body. The findings also suggest that as fashion designers develop their skills, they cease looking at the surface features of clothing and adopt a more holistic and integrated approach that considers how a final garment could be realised for specific clients.

The coincidence-anticipation timing (CAT) task assesses one facet of cognitive and motor performance and is used to understand the human visuo-motor system involved in intercepting the moving object. To assess the test-retest reliability and the concurrent validity in the "Bridge Games" package (Bridge) developed to assess the CAT task, the scores of 224 healthy subjects (M = 52.2, SD = 19.5 years old) were measured using the Bridge and the 'gold standard' Bassin Anticipation Timer (Bassin). A mean block of absolute, constant, and variable errors was calculated. Reliability and validity were expressed using intraclass correlation coefficients (ICC[subscript 2,k]), standard error of measurement, minimal detectable change, and Pearson's correlation. Reliability was good to excellent for all blocks (0.73 = ICC = 0.88), and the validity was good to excellent when compared using Pearson's correlation coefficient, suggesting that the two tests may have similar properties. Bridge is an alternative to existing clinical tests for the CAT task.

To identify the most important competencies for college graduates to succeed in the 21st century workforce, we conducted an analysis of the Occupational Information Network (O*NET) database. O*NET is a large job analysis operated and maintained by the U.S. Department of Labor. We specifically analyzed ratings of the importance of abilities (52 ratings), work styles (16 ratings), skills (35 ratings), and knowledge (33 ratings) to succeed in one's occupation. First, we conducted descriptive analyses. Next, data were split into 2 sets, according to the theoretical structure proposed by the O*NET content model, and principal component analyses (PCAs) were run on each dataset. The PCAs identified 15 components: problem solving, mechanical skills, service orientation, cultural literacy, business literacy, science literacy, civic literacy, information processing, athleticism, visual acuity, fluid intelligence, communication skills, teamwork, achievement/innovation, and attention to detail/near vision. Components were then ranked in importance using the mean component scores over all occupations. A comparison of this ranking with previous 21st century competencies frameworks suggested that 5 competencies stand out as important for most occupations: problem solving (e.g., complex problem solving), fluid intelligence (e.g., category flexibility), teamwork (e.g., cooperation), achievement/innovation (e.g., persistence), and communication skills (e.g., oral expression). Consistent with this conclusion, a correlation of component scores with wages found that 4 of these 5 competencies were strongly related to wages, with the exception being teamwork.

It is well established that girls and boys perform differently in traditional examinations in most countries. This study looks at a sample of 754 school students in Kuwait (aged about 13) and explores how boys and girls differ in the performance in a range of tests related to learner characteristics. The fundamental question is how boys and girls differ in these learner characteristics and do any of the differences relate to examination performance. If the development of such learner characteristic is open to experiences in the formal learning situations, then this opens the door to possible ways to encourage the development of such characteristics, with possible concomitant enhancement of academic performance. The importance of this cannot be underestimated for it gives curriculum planners, textbook writers teachers and examiners potential tools for enhanced learning. In terms of gender, it may well offer some ways forward to ensure that there is equality of opportunity in achieving high academic performance. It is found that girls outperform the boys in tests which measure extent of field dependency, extent of divergency and skills with the visual-spatial (all at p < 0.001). Confirming previous studies, the girls markedly outperform the boys in all school subject examinations but there are no differences in their measured working memory capacities. In looking at the relationships between various combinations of the measurements made, it is found that boys are much more dependent on working memory than girls in performing in examinations, and the boys are also much more dependent on employing skills related to divergent thought in achieving success in examinations. These observations are interpreted in terms of the way boys and girls learn, with girls being more conscientious and willing to memorise than the boys who, in turn, have to rely on working things out for success: girls tend to memorise; boys tend to try to work it out. This may offer an explanation of the greater success of girls in typical examinations where the accurate recall of information is so often the key to success.

Reductions in stimulus quality may disrupt the reading performance of older adults more when compared with young adults because of sensory declines that begin early in middle age. However, few studies have investigated adult age differences in the effects of stimulus quality on reading, and none have examined how this affects lexical processing and eye movement control. Accordingly, we report two experiments that examine the effects of reduced stimulus quality on the eye movements of young (18-24 years), middle-aged (41-51 years), and older (65+ years) adult readers. In Experiment 1, participants read sentences that contained a high- or low-frequency critical word and that were presented normally or with contrast reduced so that words appeared faint. Experiment 2 further investigated effects of reduced stimulus quality using a gaze-contingent technique to present upcoming text normally or with contrast reduced. Typical patterns of age-related reading difficulty (e.g., slower reading, more regressions) were observed in both experiments. In addition, eye movements were disrupted more for older than younger adults when all text (Experiment 1) or just upcoming text (Experiment 2) appeared faint. Moreover, there was an interaction between stimulus quality and word frequency (Experiment 1), such that readers fixated faint low-frequency words for disproportionately longer. Crucially, this effect was similar across all age groups. Thus, although older readers suffer more from reduced stimulus quality, this additional difficulty primarily affects their visual processing of text. These findings have important implications for understanding the role of stimulus quality on reading behavior across the lifespan.

Visual Impairments (VIs) are ranked as the fourth most common disability in the United States and are viewed as the most common restricting condition during childhood. It has been reported that 17% to 25% of school-aged children have some degree of a vision problem, thus interrupting their potential to reach optimal growth and learning in school. This is mostly due to the lack of professional eye care many children receive (AOA). Consequently, early intervention (EI) and stimulation for these children can greatly aid in their overall development and success upon entering school. The goal of this article is to provide more information for parents and professionals on VIs as well as ways to ensure a typical developmental trajectory in children through the use of practical techniques.

The prevalence of refractive error and ocular disorders among infants and young children with severe behavioral problems and developmental disorders is not well defined, particularly in developing countries. We performed a retrospective review of ophthalmic examinations performed during a National Institutes of Health--funded cohort study of very young children in Peru with behavioral problems and at risk for developmental disorders. Two-hundred twenty-two children between the ages of 0 and 4 years (mean 2.2 ± 0.9 years) were examined and 100 (45.0%) had an abnormal ocular exam. Overall, the prevalence of refractive error was 33.3%, nystagmus was 12.2%, and strabismus was 10.9%. Among children with Down syndrome, refractive error ranged from 46.2% at age 2 to 85.7% at age 4. Refractive error and ocular disorders are highly prevalent even at a young age in children with behavioral problems and developmental disorders. Much of the visual impairment in this population is treatable; early identification and intervention can have a lifelong positive impact on neurodevelopment.
