Medical simulations allow trainees to work within teams to develop their self-regulated learning (SRL) and socially-shared regulated learning (SSRL) skills (Bransen et al., 2022). Both skillsets help to better prepare medical trainees for the multifaceted challenges inherent in clinical practice. SRL skills are imperative in empowering learners to optimize their performance and become autonomous guiders of their own learning (Jarvela & Hadwin, 2013), while SSRL skills are needed to ensure that teams can work collectively to regulate their behaviors and to regulate their own learning to make decisions (Hadwin & Oshige, 2011). Questions remain about not only how medical trainees' behaviors, regulation strategies, and physiological responses vary while they participate in a high-fidelity medical simulation, but how additional data channels to measure human response can provide indicators of teams' regulation strategies. Using a mixed-methods convergence design incorporating multimodal data (Azevedo & Gaševic, 2019), including behavioral, SRL and SSRL codes, and electrodermal activity, researchers studied twenty-nine (N = 29) 1st to 3rd year medical residents as they engaged in high-fidelity simulation scenarios. Results suggest that the mean-level of psychophysiological activation increase as simulations progress, in conjunction with an increase in team-regulated learning strategies to manage the effective provision of patient care from initial contact through to the delivery of critical procedures. These results provide valuable insights into the advancement of a team regulation-based framework within a high-fidelity medical simulation environment, leveraging multimodal data to reach an understanding of medical trainees' adoption of team-based approaches to team-regulation during simulation scenarios.

The aim of this study was to investigate current trends in research of math anxiety (MA) through bibliometric perspective. Three main clusters were formed based on author keywords: cognitive correlates (working memory, attention, numerical cognition, mental arithmetic), psychological factors and effects (self-concept and self-efficacy, motivation, confidence, attitudes), and educational context (PISA, measurement, gender differences, math achievement, math education, assessment). Analysis of the index keywords revealed somewhat different organization with two dominant clusters: the experimental cluster in which the most frequent are psychophysiological measures and terms and the correlational cluster in which the topics of MA psychosocial factors are most represented. The map of bibliographic coupling showed several relatively separated groups of authors with different focus in cited references. However, a map of co-citation of authors revealed closeness of these separated groups, with Beilock, S. L. and Ashcraft, M. H. by far the most-cited authors in this field.

The reliability of cognitive demand measures in controlled laboratory settings is well-documented; however, limited research has directly established their stability under real-life and high-stakes conditions, such as operating automated technology on actual highways. Partially automated vehicles have advanced to become an everyday mode of transportation, and research on driving these advanced vehicles requires reliable tools for evaluating the cognitive demand on motorists to sustain optimal engagement in the driving process. This study examined the reliability of five cognitive demand measures, while participants operated partially automated vehicles on real roads across four occasions. Seventy-one participants (aged 18-64 years) drove on actual highways while their heart rate, heart rate variability, electroencephalogram (EEG) alpha power, and behavioral performance on the Detection Response Task were measured simultaneously. Findings revealed that EEG alpha power had excellent test-retest reliability, heart rate and its variability were good, and Detection Response Task reaction time and hit-rate had moderate reliabilities. Thus, the current study addresses concerns regarding the reliability of these measures in assessing cognitive demand in real-world automation research, as acceptable test-retest reliabilities were found across all measures for drivers across occasions. Despite the high reliability of each measure, low intercorrelations among measures were observed, and internal consistency was better when cognitive demand was estimated as a multi-factorial construct. This suggests that they tap into different aspects of cognitive demand while operating automation in real life. The findings highlight that a combination of psychophysiological and behavioral methods can reliably capture multi-faceted cognitive demand in real-world automation research.

Physiological measures associated with emotional expressions have been used extensively in lab- and, more recently, digital-learning settings. However, the portable and ubiquitous nature of hardware that measures these physiological features makes them particularly useful in situations where you do not want the hardware to be too obtrusive, like in contexts of informal learning. In this proof-of-concept study, we apply skin conductance methods that measure Electrodermal Activity (EDA) to a family everyday activities context, in which a parent and their children, complete several science learning activities, while being recorded by both video and EDA hardware. We analyse the resulting data in three different ways: (i) a peak analysis in software recommended by the hardware provider, (ii) a conventional, qualitative microanalysis, and (iii) a method mainly used by econometricians to discover 'structural breaks' in time series data. We conclude that all three provide a piece of the overall puzzle, revealing up- and down-sides of each method.

This present study examines the psycho-emotional and psychophysiological effects that variations in the tempo of background music have on learners who are completing reading comprehension tests while being monitored used multi-modal computer technology. Results of seventy-four (N = 74) participants indicated that listening to fast tempo music (150 bpm) predicted lower reading comprehension scores, increased emotional expressions of fear, joy and contempt, and higher skin conductance responses (SCRs). Results indicated that participants were more likely to produce higher scores while listening to slow tempo music (110 bpm), but such findings were not connected to significant differences in facial emotion expressions or psychophysiological responses. Contrasting these were control/no-music conditions in which participants exhibited moderated scores. Results from the fast-tempo condition can possibly be attributed in part to an affective valence of emotions and psychophysiological responses, as the multimodal data suggests that a combined regulatory mechanism may be at play while engaged in a learning task. This paper raises several questions regarding the use and effects of background music in performance-based learning settings and the role of affective-stimuli on cognitive regulation.

Population coding models provide a quantitative account of visual working memory (VWM) retrieval errors with a plausible link to the response characteristics of sensory neurons. Recent work has provided an important new perspective linking population coding to variables of signal detection, including d-prime, and put forward a new hypothesis: that the distribution of recall errors on, for example, a color wheel, is a consequence of the psychological similarity between points in that stimulus space, such that the exponential-like psychophysical distance scaling function can fulfil the role of population tuning and obviate the need to fit a tuning width parameter to recall data. Using four different visual feature spaces, we measured psychophysical similarity and memory errors in the same participants. Our results revealed strong evidence for a common source of variability affecting similarity judgments and recall estimates but did not support any consistent relationship between psychophysical similarity functions and VWM errors. At the group level, the responsiveness functions obtained from the psychophysical similarity task diverged strongly from those that provided the best fit to working memory errors. At the individual level, we found convincing evidence against an association between observed and best-fitting similarity functions. Finally, our results show that the newly proposed exponential-like responsiveness function has in general no advantage over the canonical von Mises (circular normal) function assumed by previous population coding models.

Stress experienced during high-risk decision-making may impair performance, but can also be a cue, provoking the move from intuitive and automatic application of expertise to reflective and deliberative approaches. This article reports an exploratory intervention designed to provoke reflection-in-action and, ultimately, to improve practice decision making in experienced clinicians. The intervention combined: classroom-based education on decision-making science, practice-based self-monitoring with the aid of wearable technology, decision-making logs intended to provoke reflection, and opportunities to engage in guided reflection-on-action. The intervention supported recognition and use of physiological cues to moderate action and decision making, and provoked experienced professionals to reconnect with the element of surprise they experienced early in their careers, and to use these moments to improve their practice.

Second language (L2) researchers have long acknowledged the role of language anxiety in communication processes, such that learners with greater language anxiety tend to be less willing to engage in communication. However, little research has explored links between L2 speakers' perceptions of conversation and dynamic measures of anxiety. Therefore, this study measured 60 L2 English speakers' galvanic skin response (a physiological index of anxiety) during conversation. After the conversation, speakers evaluated themselves and their partner in terms of speech fluency and comprehensibility, engagement, and anxiety, and responded to trait-anxiety and social network questionnaires. Correlational analyses explored relationships between speakers' trait-anxiety, social network characteristics, self- and peer-perceptions and five levels of physiological response during conversation. Findings revealed that high arousal during interaction was related to speakers' negative self-perceptions of speech fluency and negative perceptions of their partner's engagement. Implications are discussed regarding state-anxiety as triggered by partner- or task-specific experiences.

This quasi-experimental study examines the effects of the Somatic Experience Stabilization Program (SESP) on post-traumatic stress, mindfulness, and social support levels among refugee women. This study was conducted with 22 women who applied to a non-governmental organization for social and psychological support. Impact of Event Scale Revised (IES-R), Mindfulness Attention Awareness Scale (MAAS) and Multidimensional Scale of Perceived Social Support (MSPSS) were utilized for pre-test, post-test, and follow-up tests. While experimental group received a six-session SESP intervention developed by the researcher, control group received no intervention. SESP for refugee women was found to be significantly effective in decreasing post-traumatic stress and increasing mindfulness and social support levels. The effects of the program persisted during the follow-up test.

The purpose of the current study was to conduct a qualitative and experimental analysis of a culturally informed police safety skills training for adolescents with autism spectrum disorder (ASD). The current study focused primarily on meeting the unique training needs of Black adolescents with autism spectrum disorder (ASD). A single case design was used to evaluate the initial efficacy and acceptability of a culturally responsive training method. Preliminary evidence about the physiological ramifications of police contact were also collected to begin to examine the broader behavioral and psychophysiological nature of youth's experiences. The current experimental design included in-person simulated contexts that youth, and caregivers, endorsed as relevant to their normal lives, which greatly strengthened the ecological validity of the approach.

Instructor support is associated with various positive outcomes for students. Self-care (taking care of one's physical, mental, and emotional health) has become a mainstream concept. Self-care may be one way for students to increase wellness, particularly students enrolled in rigorous science courses. If self-care is facilitated or suggested by an instructor, it may lead to students' feelings that they are supported by the instructor. In the study discussed in this article, 45 students enrolled in a physiological psychology course (an upper-level online course) participated in a control group section or an experimental group section that included an integrated self-care blog and supporting communication. Across both groups, a sense of classroom community and professor-student rapport were related to a variety of positive perceptions about the course and instructor. Students in the self-care section rated the course more positively across several variables, but this rating only nearly reached significance for instructor warmth. The self-care blog was easy to implement and well received by students. Integrated discussions about self-care may help students connect with their instructor and can facilitate skills that will benefit students in future semesters.

The impact of media and social networks on users is growing. The fact that commercial activity is flooding most social networks motivates us to enquire about the success factors of posts, and to try to determine if the impact is greater or lesser depending on gender. Attracting attention and exciting the user or customer are the main objectives of advertising, especially interactive advertising. This quantitative research measures the psychophysiological signals of the attentional level and the emotional level of people taking into account gender, through Sociograph, when they visualize Instagram stories of real influencers. To measure the electrodermal activity by means of two electrodes, a measurement instrument is used which integrates the traditional register of the Electrodermal Activity (EDA) and processes the information of the individuals. A questionnaire, the screen to display the Instagram story, the Instagram stories of the influencers, a registration protocol and a record sheet of the activity sequences are used. We observed that a greater number of followers implies greater emotional activation, although it translates into negative emotions, and a greater emotional activation in men than in women, although it is they who show positive emotions towards the video and would make an act of purchase through Instagram.

Cognitive load theory is one of the most influential theoretical explanations of cognitive processing during learning. Despite its success, attempts to assess cognitive load during learning have proven difficult. Therefore, in the current study, students' self-reported cognitive load after the problem- solving process has been combined with measures of physiological data, namely, electrodermal activity (EDA) and skin temperature (ST) during the problem-solving process. Data was collected from 15 students during a high and low complex task about learning and teaching geometry. This study first investigated the differences between subjective and physiological data during the problem- solving process of a high and low complex task. Additionally, correlations between subjective and physiological data were examined. Finally, learning behavior that is retrieved from log-data, was related with EDA. Results reveal that the manipulation of task complexity was not reflected by physiological data. Nevertheless, when investigating individual differences, EDA seems to be related to mental effort.

The aim of this study was to validate the Teacher Stress Inventory (TSI) for use in a South African context. The process of scale validation also sheds significant light on this culturally diverse group of participants' levels of psychological wellbeing and physical health, and its association with the level of stress that teachers reported. Using a cross-sectional survey design, Caucasian (n = 209) and African (n = 200) educators' subsiding in the North-West Province of South Africa, completed the TSI, together with a number of self-report and physiological measures of stress and well-being. In contrast to the five factors of the TSI identified in US samples, statistical analysis yielded a two-factor model (i.e. "General circumstance-related stress and Learner-related stress") with satisfactory reliability indices. Significant correlation with measures of psychological and physiological health also reflected positively on the criterion-related validity of the scale. The TSI proved to be a useful, brief self-report questionnaire for the assessment of teacher stress in this cohort of South African teachers.

Objective: Academic examinations are a frequent and significant source of student stress, but multimodal, psychophysiological studies are still missing. Participants & methods: Psychological and physiological variables were assessed on 154 undergraduate students in daily life using e-diaries resp. blood pressure devices at the beginning of the semester, and again before an examination. Results: Multilevel analysis revealed lower calmness, more negative valence, higher task-related stress, higher demands, lower perceived control, lower frequency of social contact, and a higher desire to be alone during the examination period (all p values < 0.0001), as well as lower ambulatory systolic blood pressure (p = 0.004), heightened cortisol at awakening (p = 0.021), and a smaller increase in cortisol (p = 0.012). Conclusions: Our study revealed empirical evidence that examination periods are not only associated with indicators of dysphoria, stress, and social withdrawal but also by altered physiological processes, which might reflect anticipatory stress and withdrawal effects.

To examine the implications of the transition from face-to-face to online learning from a psychobiological perspective, this study investigated potential differences in physiological stress parameters of students engaged in online or face-to-face learning and determined whether these can be identified as possible mediators between learning experience and achievement emotions. In a randomized experimental field study, medical students (n = 82) attended either regular face-to-face classes of the microscopic anatomy course or the same practical course online using Zoom videoconferencing platform. The present study investigated Heart Rate Variability (HRV) and salivary cortisol concentration as stress correlates, within the contexts of online and face-to-face learning and compared these parameters with a control group that was measured at rest. Additionally, participants completed a standardized questionnaire about their experienced emotions in relation to task achievement and subjective stress levels. A significant reduction in HRV was found in face-to-face learning, suggesting stronger stress responses in the face-to-face learning environment ([eta][superscript 2] = 0.421, P < 0.001). Furthermore, participants engaged in face-to-face learning showed significantly higher cortisol concentrations ([eta][superscript 2] = 0.115, P = 0.032). Additionally, increased sympathetic activation correlated with the discrete positive emotion of enjoyment exclusively within the face-to-face condition (r = 0.365, P = 0.043). These results indicate that the transfer of a face-to-face practical course in microscopic anatomy to an online learning environment is associated with decreased sympathetic and enhanced vagal cardiovascular influences, together with lower cortisol concentrations in healthy medical students.

Discussions on how to conserve and provide enough water has become one of the most highly debated issues in modern society. Although many Extension efforts have engaged the public in understanding behavior and attitudes toward water conservation, limited research has focused on understanding how agriculturalists respond to water conservation messages. The goal of this study was to employ the use of a psychophysiological measure to determine what message components elicited increased information processing during exposure to two water conservation videos. When the two videos were compared in total, no significant difference in heart rate was observed. However, a more granular analysis of phasic or short-term periods of heart rate deceleration revealed five segments of increased cognitive resource allocation while viewing the scientific video and three segments during the testimonial evidence video. Finally, self-report data approached statistical significance, with the subjects reporting greater elaboration while viewing the testimonial evidence video compared to the scientific video treatment. These findings provide unique evidence suggesting that farmers and ranchers allocate greater cognitive resources to scientific evidence, on screen graphics, and narrated statistics.

One of the recommended approaches in instructional design methods is to optimize the value of working memory capacity and avoid cognitive overload. Educational neuroscience offers novel processes and methodologies to analyze cognitive load based on physiological measures. Observing psychophysiological changes when they occur in response to the course of a learning session allows adjustments in the learning session based on the individual learner's capabilities. The availability of non-invasive electroencephalogram (EEG)-based devices and advanced near-real-time analysis techniques have improved our understanding of the underlying mechanisms and have impacted the way we design instructional methods and adapt them to the current learner's cognitive load and valence states. We will review Cognitive Load Theory, how cognitive load may be measured, and how analysis of EEG data can be applied to enhance learning through real-time measurements of the learner's cognitive load. We show a learning experiment in an attempt to provide a proof of concept of learning and real-time measures of EEG as indicators of mental states.

This paper presents a comprehensive review and a specific example implementation of a minimally invasive technique that can be used to make quantitative measurements of a subject's Electro-Dermal Activity (EDA) in educational technology studies. The Q sensor is a low-cost wireless sensor that can be worn on the wrist to measure a subject's response to various stimuli in both laboratory and natural education research settings. The example application shown here is from a study on presence while viewing two different screen sizes used in a Virtual Reality (VR) system. It is recommended that EDA data be used in conjunction with other data, such as from other types of sensors and from qualitative instruments such as surveys, because human EDA response to a given environment and stimuli is not always consistent. EDA sensors show great promise as an effective tool that can be used in educational technology research.

Current interdisciplinary medical training calls for reforms and innovations in the assessment of pathophysiology education. Formative assessment is used to monitor student learning to provide ongoing feedback that can improve both learning and teaching. Beginning in 2016, we implemented a formative assessment composed of case-based multiple-choice questions (MCQs) for all students in all majors. In 2017, case study questions began to be employed in the formative assessment, and student-set, case-based questions were further introduced. Aiming to gather the students' suggestions and feedback on the mixed-method assessment, we conducted a survey on aspects such as the effectiveness of the assessment, assessment content and completion, opinions on student-set questions, and the impact on pathophysiology learning for students from 2017 to 2019. In addition, we compared students' semesterly final scores with those of previous students and evaluated the relationship between formative and summative assessment scores. The results for 1,277 students clearly showed that the reformed formative assessment system was well received by the students. The students thought that the formative assessment not only allowed for the provision of real-time feedback on the effectiveness of teaching and learning but also nurtured self-motivation, the development of analytical and problem-solving skills, and collaborative efforts. Both the semesterly final scores and the proportions of students scoring in higher score ranges increased after the implementation of the formative assessment, and the summative assessment scores were positively related to the formative assessment scores. Consequently, the reformed formative assessment system significantly improved the quality of pathophysiology education.

The efficacy of tutoring as an instructional strategy mainly lies on the moment-by-moment correspondence between the help provided by a tutor and the tutee's learning needs. The model presented in this paper emphasizes the pivotal role of monitoring and regulation, both by the tutor and the tutee, in attaining and maintaining affective and cognitive states conducive to student's learning. This perspective highlights the hypothesis that the scarcity of the information that the tutor and tutee have access to during natural interaction leads to suboptimal learning interactions. As a potential response to this lack of information, it is argued that methodologies from cognitive and affective neuroscience can provide pertinent information during or after a learning interaction, and that this information can significantly empower students and tutors. Projected empirical research could lead to a dramatic reinterpretation of 35 years of already fruitful tutoring research.

Psychophysiological responses have been studied as objective indicators for measuring a learner's cognitive load. Previous studies have correlated pupil dilation or fixation length with increased cognitive load. Our aims were to confirm whether these findings could be applied in a general learning context and to verify the additivity hypothesis of cognitive load theory based on psychophysiological responses. Three responses (i.e., mean pupil diameter, area under the pupil response curve, and sum of fixation duration) were recorded while 94 participants completed a computer-based test. Participants were randomly assigned to low (n = 46) or high (n = 48) extraneous cognitive load conditions. Because the given test, which consisted of a low and a high task complexity problem, was the same for all participants, the difference in intrinsic cognitive load was compared as a within-subjects factor. Each psychophysiological indicator was calculated and compared under different intrinsic and extraneous cognitive load conditions. The results showed that psychophysiological responses significantly distinguished the differences in intrinsic and extraneous cognitive loads. In addition, the sum of the different types of cognitive loads corresponded to the total cognitive load. Based on the results, further studies are suggested to apply psychophysiological responses as the standard of judgment for different levels of cognitive load.

Cost and time constraints make it challenging to include hands-on laboratory experiences in psychology courses, yet engaging laboratory experiences can increase scientific literacy and appreciation. The present study tested whether learning by observing could also increase scientific literacy (knowledge of social neuroscience). We additionally assessed whether the technology mattered, by comparing students who participated in a "low-technology" demonstration (finger pulse count) versus a "high-technology" demonstration (pulse recording via psychophysiological recording equipment). Undergraduate students observed pulse rate measures prior to and following a social challenge, in a 2 (Student Type: Introductory vs. Advanced) × 2 (Technology: High vs. Low) factorial design. Results revealed that technology yielded equal effects on scientific literacy, while perceived learning for psychology as a science increased significantly (albeit modestly) for students in the high-technology condition. These data confirm that adding laboratory experiences of any type can facilitate scientific literacy in introductory and advanced psychology students.

This research investigates whether a short mindfulness exercise can reduce children's psychophysiological stress reactions in the face of a performance task. To answer the question, a randomized controlled trial with 106 elementary school children, aged between 5 and 11 years, was conducted. An intervention group completed a two-minute breathing exercise, whilst a comparison group watched a short video, before both groups performed a stress-evoking Stroop test. The stress levels of both groups were measured via galvanic skin response and compared. It was hypothesized that the comparison group would show a higher stress reaction during the stress-evoking task than the intervention group. Contrary to the hypothesis, results show that the intervention group had a higher psychophysiological stress reaction during the task than the comparison group. However, the stress reaction to the announced difficulty of the task was smaller in the mindfulness group than in the comparison group. Results are discussed based on different theoretical mechanisms of mindfulness. Directions for future research include the use of different techniques and durations of mindfulness interventions, different control group activities and stress-test operationalizations, as well as the distinction between age groups.

Literature indicates that both academic tasks (Deater-Deckard et al. 2013; Skinner et al. "Educational and Psychological Measurement," 69(3): 493-525, 2009) and video gaming (Irwin "The Journal of Psychology," 133, 157-164, 1999; Laffan et al. "Computers in Human Behavior," 65, 544-549, 2016; Whitton "Simulation & Gaming," 42(5), 596-609, 2011) have qualities that engage and captivate individuals. This case study reports the findings of a new method for simultaneously capturing the emotional, psychophysiological response and personal experiences of one expert videogamer and one expert writer (N = 2). This method used a combination of 1) participant pre- and post- task activities/objectives questionnaires, 2) measurement of an engaged task using Galvanic Skin Response (GSR), Electroencephalogram (EEG), and facio-muscular emotional recognition "Emotient" software, and 3) a Flow State Scale (FSS-2) to understand the participant's depth of engagement. After completing a thematic analysis of each expert's activity, findings indicated both experienced a flow-like state that coincided with increased facio-emotional values of confusion (D'Mello et al. "Learning and Instruction," 29, 153-170, 2014), decreased GSR, and increased EEG brain activity (Beta and Gamma), providing indicators of engagement. This combination of emotional and psychophysiological indicators that coincide with goal attainment suggests the possibility of shared states that quantify engagement across different tasks. The findings provide an outlet to explore the characteristics of complex learning tasks and suggest the possibility of universal indicators of individualized engagement across learning domains.

Introduction: Anxiety is an emotion which is characterized by a set of cognitive, psychophysical and behavioral symptoms, showed by a subject before some situations which are perceived as threatening or dangerous. The aim of the present work was to know the relationship between anxiety, emotional intelligence and personality, as well as the predictive capacity of emotional intelligence and personality on anxiety. Method: To carry out this study, a sample of 140 participants aged between 19 and 28 years old (M = 22.57, SD = 2.16), belonging to Childhood and Primary Education Degrees of two Spanish universities was recruited. The study sample completed Emotional Quotient Inventory, Trait Meta-Mood Scale-24, NEO PI-R Personality Inventory and Anxiety Situations and Answers Inventory. Results: The correlation analysis revealed the existence of statistically significant relations between the constructs evaluated (emotional intelligence, personality and anxiety). On the other hand, multiple hierarchical regression analysis showed that some of the dimensions of emotional intelligence and personality significantly predicted anxiety levels. Discussion or Conclusion: The evaluation of the factors linked to anxiety favors the planning of programs which improve its treatment and prevention.

Over the last decade, there has been a renewed interest in capturing twenty-first century skills using new data collection tools. In this article, we leverage an existing dataset where electrodermal activity (EDA) was used to identify markers of productive collaboration. The data came from 42 pairs of participants (N = 84) who had no coding experience and were asked to program a robot to solve a variety of mazes. Because little is known on how physiological synchrony relates to collaborative learning, we explored four different measures of synchrony: Signal Matching (SM), Instantaneous Derivative Matching (IDM), Directional Agreement (DA) and Pearson's Correlation (PC). Overall, we found PC to be positively associated with learning gains (r = 0.35) and DA with collaboration quality (r = 0.3). To gain further insights into these results, we also qualitatively analyzed two groups and identified situations with high or low physiological synchrony. We observed higher synchrony values when members of a productive group reacted to an external event (e.g., following instructions, receiving a hint), oscillations when they were watching a video or interacting with each other, and lower values when they were programming and / or seem to be confused. Based on these results, we developed a new measure of collaboration using electrodermal data: we computed the number of cycles between low and high synchronization. We found this measure to be significantly correlated with collaboration quality (r = 0.57) and learning gains (r = 0.47). This measure was not significantly correlated with the measures of physiological synchrony mentioned above, suggesting that it is capturing a different construct. We compare those results with prior studies and discuss implications for measuring collaborative process through physiological sensors.

Children with autism spectrum disorder exhibit significant difficulties with emotion regulation. Respiratory sinus arrhythmia is a biomarker for processes related to emotion regulation, with higher baseline rates linked to beneficial outcomes. Although reduction in respiratory sinus arrhythmia in response to challenge can index adaptive processes in community samples, excessive withdrawal may suggest loss of regulatory control among children with clinical concerns. Psychophysiological risk for problems may be protected against or exacerbated by parenting environments more or less supportive of the development of children's regulatory competence. Respiratory sinus arrhythmia was examined in 61 children with autism spectrum disorder ages 6-10 years in relation to externalizing behavior, and parenting was considered as a moderator. Respiratory sinus arrhythmia was obtained during laboratory tasks, and positive parenting, negative parenting, and children's externalizing behaviors were each indexed through multiple methods. Respiratory sinus arrhythmia reactivity interacted with negative, but not positive parenting. Higher respiratory sinus arrhythmia reactivity was associated with more externalizing behavior under conditions of higher negative parenting, but with lower externalizing behavior at lower levels of negative parenting. Similarly, negative parenting was only associated with externalizing behaviors in the context of high child respiratory sinus arrhythmia reactivity. Implications for our understanding of emotion regulation in children with autism spectrum disorder, and for related interventions, are discussed.

Purpose: The current study investigated the effect of attention on heaviness perception and its physiological and kinematic contributions. Method: Participants lifted objects that varied in mass and volume while their muscle activity and movement were recorded. Participants were instructed to pay attention to their arm (internal) or the object (external). Results: While heaviness perception did not change as a function of attention, whether muscle activity and movement combined for perception differed across attention conditions. Specifically, muscle activity and movement combined to significantly predict heaviness perception in the external condition, but not the internal condition. Additionally, movement was more salient for perception in both conditions compared to previous research investigating the contribution of muscle activity and movement to heaviness perception. Conclusion: It is suggested that these results support the constrained action hypothesis, which suggests that adopting an external focus of attention benefits motor task performance and learning, and should be further explored in the context of a theory of haptic perception that suggests that the medium for haptic perception is the multifractal tensegrity structure of the body.

An individual's emotions system can be conceived of as a synchronized, coordinated, and/or emergent combination of physiology, experience, and behavioral components. Together, the interplay among these components produce emotional experiences through coordinated excitatory positive feedback (i.e., the mutual amplification of emotion concordance) and/or inhibitory negative feedback (i.e., the damping of emotion regulation) processes. Different system configurations produce differential psychophysiological reactivity profiles, and by implication, differential moment-to-moment emotional experience and long-term development. Applying dynamic systems models to second-by-second psychophysiological and experience time-series data collected from 130 adolescents (age 12.0 to 16.7 years) completing a social stress-inducing speech task, we describe the configuration of adolescents' emotion systems, and examine how differences in the dynamic outputs of those systems (psychophysiological reactivity profile) are related to individual differences in trait anxiety. We found substantial heterogeneity in the coordination patterns of these adolescents. Some individuals' emotion systems were characterized by negative feedback loops (emotion regulation processes), many by unidirectionally connected or independent components, and a few by positive feedback loops (emotion concordance). The reactivity dynamics of respiratory sinus arrhythmia were related to adolescents' level of trait anxiety. Results highlight how dynamic systems models may contribute to our understanding of interindividual and developmental differences.

Both the concept of well-being and the work of early childhood educators are complex. To date, research concerning educators' well-being has lacked a comprehensive conceptualisation that reflects these complexities. With increased research, policy and practice attention, a clearly articulated conceptualisation is now needed to guide empirical research and practical efforts to better support educators' well-being. In this article, the authors draw on multidisciplinary perspectives to propose such a conceptualisation. Philosophical, psychological, physiological, organisational science and sociological sources are explored and critiqued for their relevance to early childhood educators' well-being. Key aspects of these sources, and Bronfenbrenner's ecological systems theory, are brought together to argue for a morally anchored conceptualisation which acknowledges that educators' well-being is indivisible from the contexts in which it is experienced.

Effectively regulating negative emotions is important for successful self-regulated learning. However, research has hardly examined which emotion regulation strategies benefit self-regulated learning. In an experimental study, it was examined whether positive reappraisal facilitates self-regulated learning by counterbalancing the depletion of self-control resources. Sixty-one university students engaged in either positive reappraisal or expressive suppression to regulate negative emotions induced by a film clip and then worked on a self-regulated learning task. Participants who engaged in positive reappraisal experienced more positive emotions after the film and had more self-control resources available than participants who used expressive suppression. Moreover, positive reappraisal increased skin conductance during emotion regulation, as compared to expressive suppression. Irrespective of emotion regulation type, positive emotions predicted post-film availability of self-control resources which was positively associated with subsequent self-regulated learning. The results demonstrate beneficial affective and resource-related consequences of positive reappraisal as well as its potential for fostering self-regulated learning.

Background: Self-selected exercise intensity (SSEI) promotes higher affect (pleasure) during exercise, but its reliability is still unclear. Purpose: to evaluate the test-retest reliability and the minimum detectable change of the perceptive and physiological responses in two sessions of SSEI on treadmill in elderly women. Method: Twenty elderly women (ages 65.3 [plus-minus] 4.2 years) performed two 20-min laboratory-based treadmill aerobic exercise sessions with self-selected intensity. During the sessions, %VO[subscript 2max], %HR[subscript reserve], affect, and rating of perceived exertion (RPE) were recorded. Reliability was calculated using the intraclass correction coefficient (ICC) and Bland-Altman plots. The minimum detectable change (MDC) was also calculated. Results: ICC values were 0.98 for % VO[subscript 2max], 0.83 for % HR[subscript reserve], 0.85 for affect, and 0.80 for RPE. No differences were observed in mean values between sessions for all the variables. MDCs were lower than 0.7% for VO[subscript 2max], 11.7% for HR[subscript reserve], 0.7 for affect, and 0.8 for RPE. Bland-Altman plots showed a bias of 0.50% for HR[subscript reserve], 3.2% for VO[subscript 2max], 0.05 for affect, and -0.35 for RPE. Conclusion: Self-selected intensity during aerobic exercise performed on treadmill is reliable, which promotes adequate and lower MDC values on physiological and perceptual responses in elderly women.

The purpose of this study was to identify the feasibility of using the pupil dilation and heart rate variability (HRV), to diagnose learners' changing cognitive load in a video learning setting. The pupil dilation and HRV of 23 participants were recorded during their learning progress, and the learning materials, including differences in task complexity, were presented to the groups of distinct prior knowledge. The results showed that the high prior knowledge group had lower pupil size than the low prior knowledge group, but the difference was not statistically significant. However, the ratio of low frequency to high frequency power (LF/HF ratio) was higher in the high prior knowledge group than in the low prior knowledge group throughout the entire learning process, and the two groups showed different arousal patterns. Overall, learners' changing cognitive load could be measured and visualised based on psychophysiological responses, the types of cognitive load could be assumed by using the two indices in parallel, and this study raised practical issues to the use of pupil size as an indicator of cognitive load in video learning.

Although negative interparental conflict predicts elevated externalizing problems for children, there are individual differences in this association. Theoretically, children's abilities to coordinate physiological stress across response systems moderate the effects of interparental conflict on developmental outcomes. Past cross-sectional research has demonstrated that poor coordination of sympathetic (SNS) and parasympathetic (PNS) nervous systems puts children at a greater risk for externalizing behaviors in the context of interparental conflict. Our goal was to examine whether this same pattern is evident in adolescents and provide the first longitudinal test of this theoretical pathway. Participants were families with adolescents (10-17 years) from diverse ethnic and socioeconomic backgrounds. Parents reported conflict, were observed during a conflict discussion, and reported adolescent externalizing behaviors; parents again reported externalizing behaviors 1 year later. Adolescents experienced a stressor while skin conductance level (SCL; SNS) and respiratory sinus arrhythmia (RSA; PNS) were measured. Similar to past research with children, there were 3-way interactions between negative interparental conflict, SCL reactivity, and RSA reactivity in relation to adolescent externalizing behaviors, concurrently and prospectively. The overall pattern suggested that adolescents who displayed poorly coordinated responding displayed a positive association between interparental conflict and externalizing behaviors, whereas adolescents who showed well-coordinated responding displayed a nonsignificant or negative association. Coinhibition of the SNS and PNS may put adolescents particularly at risk for prospective externalizing behaviors. Autonomic nervous system coordination--particularly activation of the SNS and inhibition of the PNS during stress--may protect adolescents from experiencing adjustment problems in the context of interparental conflict.

A burgeoning literature supports the role of autonomic nervous system (ANS) functioning as an index of physiologic sensitivity to the environment, but extant research is limited in its focus on single branches of the ANS, childhood samples, and solely negative environmental factors. This study seeks to address these limitations by exploring whether reactivity in the parasympathetic (PNS) and sympathetic (SNS) nervous systems jointly moderate the prospective contributions of both positive (maternal involvement) and negative (maternal psychological control) aspects of the family environment to developmentally relevant outcomes in adolescence (depressive symptoms and emotion regulation). At Wave 1, adolescents (n = 352, 52% female, M age = 15.27, SD = 1.04; 65% White) and their parents completed a problem-solving discussion task, during which adolescent ANS activation was continuously monitored, and reports of maternal involvement, maternal psychological control, adolescent depressive symptoms, and adolescent emotion regulation were obtained. Adolescent depressive symptoms and emotion regulation were assessed again 1 year later (Wave 2). Results indicated that PNS and SNS reactivity jointly moderated the prospective contributions of maternal involvement and maternal psychological control to depressive symptoms and emotion regulation. Specifically, adolescents who exhibited reciprocal SNS activation appeared to be most sensitive to both positive and negative parenting environments. Adolescents exhibiting coinhibition or coactivation profiles of autonomic reactivity were comparatively unreactive to parenting. This study corroborates the notion that consideration of multiple physiological systems is critical to our understanding of biological processes in the development of emotional functioning in adolescence.

Low-cost devices have widened the use of multimodal data in experiments providing a more complete picture of behavioural effects. However, the accurate collection and combination of multimodal and behavioural data in a manner that enables reproducibility is challenging and often requires researchers to refine their approaches. This paper presents a direct replication of a multimodal wordlist experiment. Specifically, we use a low-cost Emotiv EPOC® to acquire electrophysiological measures of brain activity to investigate whether retrieval during learning facilitates the encoding of subsequent learning as measured by performance on recall tests and reflected by changes in alpha wave oscillations. Behavioural results of the wordlist experiment were replicated, but physiological results were not. We conclude the paper by highlighting the challenges faced in terms of replicating the previous work and in attempting to facilitate the reproducibility of our own experiment.

Maltreating mothers often struggle to respond sensitively to their children's distress. Examining psychophysiological processing of own child cues may offer insight into neurobiological mechanisms that promote sensitive parenting among high-risk mothers. The current study used event-related potential (ERP) methodology to examine associations between mothers' neural responses to their own child versus other children and observed sensitivity to distress. Participants included 73 mothers: 42 with histories of child protective services (CPS) involvement and 31 low-risk comparison mothers. Maternal sensitivity to child distress was coded from observations of children's blood sample collection. Late positive potential (LPP) ERP responses, which reflect sustained attention to emotionally salient stimuli, were measured when mothers viewed photos of their own child and other children. An own-other LPP difference score (own-other LPP) was computed by regressing the mean amplitude of mothers' LPP to their own child on the mean amplitude of mothers' LPP to other children. CPS-referred mothers and low-risk mothers did not differ in their LPP responses to own child, other children, or the own-other LPP. However, there was a significant interaction between group (CPS-referred vs. low-risk) and own-other LPP in predicting maternal sensitivity. Among the CPS-referred mothers, own-other LPP was significantly correlated with maternal sensitivity, with greater LPP amplitude to own versus other child associated with higher maternal sensitivity. In contrast, among the low-risk group, own-other LPP was not significantly correlated with maternal sensitivity. Findings add to our understanding of the neurobiology of sensitive parenting among high-risk mothers.

Though previous research has shown a decreased sensitivity to emotionally-laden linguistic stimuli presented in the non-native (L2) compared to the native language (L1), studies conducted thus far have not examined how different modalities influence bilingual emotional language processing. The present experiment was therefore aimed at investigating how late proficient Polish (L1)-English (L2) bilinguals process emotionally-laden narratives presented in L1 and L2, in the visual and auditory modality. To this aim, we employed the galvanic skin response (GSR) method and a self-report measure (Polish adaptation of the PANAS questionnaire). The GSR findings showed a reduced galvanic skin response to L2 relative to L1, thus suggesting a decreased reactivity to emotional stimuli in L2. Additionally, we observed a more pronounced skin conductance level to visual than auditory stimuli, yet only in L1, which might be accounted for by a self-reference effect that may have been modulated by both language and modality.

There have been numerous attempts to solve the apparent dualism of 'body' and 'mind', purportedly uniting mutually incompatible binaries through hyphenation, the creation of compound terms, or the erasure of one of the terms entirely. 'Psychophysical', 'psychosomatic' (with or without the word 'unity'), 'mind-body', 'body-mind', and 'somatic', have all been advanced as a means of articulating an undivided sense of human being. This discussion deconstructs this descriptive matrix in an attempt to expose the naked paradox of human being obscured by tacit assumptions hidden in language. In dance the idea of 'body' is often afforded priority. Dancers understanding of themselves in activity, whether performing or observing -- in the fields of learning, creating or rehearsing -- is critically affected by their conception of themselves as divided or unified beings. To say, 'there is no "body" … or "mind"' might facilitate a more productive, poietic sense of practice, a 'thinking in activity' that does not imply a dualistic ontology. This requires a practical philosophical perspective. Such 'philosophical practicality' in dancers' practice may afford them greater resilience for their future careers against the fragmentation of dis-unity that thinking of 'body' or 'mind' engenders.

We measured skin conductance response (SCR) to escalating levels of a direct social threat from a novel, ecologically-relevant experimental paradigm, the Intruder Threat Task. We simultaneously evaluated the contribution of social symptom severity and behavioral movement. Children with AS group showed less psychophysiological reactivity to social threat than controls across all three phases of the experiment. In the AS group, greater social impairment was significantly associated with reduced SCR. However, movement activity predicted SCR while diagnosis did not. Research and treatment need to account for the complex interplay of emotional reactivity and social behavior in AS. Psychophysiology studies of AS should consider the impact of possible confounds such as movement.

Physiological activities (heart rate and respiratory rate) during a word retrieval task were measured in normal participants. Word frequency demonstrated a significant effect on naming accuracy and latencies but not on physiological activities. These data will serve as a basis for comparison for individuals with a compromised language system.

While there is a general consensus in the literature that individuals with autism spectrum disorder have difficulty with cognitive empathy, much less is known about emotional empathy processing in these individuals. Most research has employed subjective self-report measures, which can often be misinterpreted or under-reported/over-reported. More objective measures such as psychophysiological recordings of arousal offer a more objective response. Furthermore, combining physiological responses with self-report ratings allows us to explore the relationship between these two responses to emotionally charged stimuli. A total of 25 individuals with autism spectrum disorder were compared with 25 matched controls on their physiological (arousal) and psychological (self-report) responses to emotionally distressing video scenes. These responses were also then compared with self-report cognitive and emotional trait empathy. Results indicate that while individuals with autism spectrum disorder appear to respond similarly to controls physiologically, their interpretation of this response is dampened emotionally. Furthermore, this dampening of self-report emotional response is associated with a general reduction in trait empathy.

The teaching of communication skills is a labour-intensive task because of the detailed feedback that should be given to learners during their prolonged practice. This study investigates to what extent our FILTWAM facial and vocal emotion recognition software can be used for improving a serious game (the Communication Advisor) that delivers a web-based training of communication skills. A test group of 25 participants played the game wherein they were requested to mimic specific facial and vocal emotions. Half of the assignments included direct feedback and the other half included no feedback. It was investigated whether feedback on the mimicked emotions would lead to better learning. The results suggest the facial performance growth was found to be positive, particularly significant in the feedback condition. The vocal performance growth was significant in both conditions. The results are a significant indication that the automated feedback from the software improves learners' communication performances.

This study investigates whether individual differences in attachment status can be detected by electrophysiological responses to loss-themed pictures. The Adult Attachment Interview (AAI) was used to identify discourse/reasoning lapses during the discussion of loss experiences via death that place speakers in the Unresolved/disorganized AAI category. In parents, Unresolved AAI status has been associated with Disorganized infant Strange Situation response, a known risk factor for psychopathology (e.g., internalizing/externalizing/dissociation). This association has been related to anomalous frightening (FR) parental behavior in the infant's presence, behavior presumed to be instigated by vulnerability to trauma-related fright. Here, psychophysiological methods were utilized to examine whether Unresolved AAI status could be detected in brain responses to subtle/symbolic reminders of loss. One year after AAI administration, 31 undergraduate women who had experienced loss (16 Unresolved) underwent continuous electroencephalogram (EEG) recording during a picture-viewing, valence-rating task. Picture onset-locked event-related potentials (ERPs) revealed millisecond responses to 4 picture categories: pleasant people, pleasant nature, cemetery (symbolic death), and gruesome death (dead or dying people). Participants' valence ratings did not differ between groups across picture categories. However, the N2 ERP, implicated in detecting stimulus salience, was selectively greater in Unresolved participants viewing cemetery scenes; it was in fact as high as the N2 for gruesome death images observed throughout the sample. Additionally, Unresolved participants exhibited a right-hemispheric P3 asymmetry across picture categories, suggestive of continuously heightened vigilance/arousal. Together, these results suggest that Unresolved AAI status is associated with greater neurophysiological sensitivity to subtle reminders of loss that may disrupt ongoing mental function.

Extant literature suggests that oppositional defiant disorder (ODD) and callous-unemotional (CU) behaviors in childhood and adolescence are associated with distinct patterns of psychophysiological functioning, and that individual differences in these patterns have implications for developmental pathways to disorder. Very little is known about the associations between psychophysiological functioning in infancy and later ODD and CU behaviors. This study examined associations between basal autonomic nervous system (ANS) functioning in infancy and ODD and CU behaviors in later childhood. Using longitudinal heart period (HP) and respiratory sinus arrhythmia (RSA) data from the Durham Child Health and Development Study (N = 206), the current study tested associations within a structural equation modeling framework, between continuous measures of HP and RSA across the first 2 years of life, and later ODD and CU behaviors at first grade. Results indicate that ODD and CU behaviors in childhood are associated with lower baseline RSA, but not HP, across infancy. The implications of these findings for developmental models of ODD and CU behaviors are discussed.
