Autistic Traits Modulate Social Synchronizations Between School-Aged Children: Insights From Three fNIRS Hyperscanning Experiments.

The current study investigated how autistic traits modulate peer interactions using functional near-infrared spectroscopy (fNIRS) hyperscanning. Across three experiments, we tested the effect of copresence, joint activity, and a tangible goal during cooperative interactions on interbrain coherence (IBC) in school-aged children between 9 and 11 years old. Twenty-three dyads of children watched a video alone or together in Experiment 1, engaged in joint or self-paced book reading in Experiment 2, and pretended to play a Jenga game or played for real in Experiment 3. We found that all three formats of social interactions increased IBC in the frontotemporoparietal networks, which have been reported to support social interaction. Further, our results revealed the shared and unique interbrain connections that were predictive of the lower and higher parent-reported autism-spectrum quotient scores, which indicated child autistic traits. Results from a convergence of three experiments provide the first evidence to date that IBC is modulated by child autistic traits.

Evaluation of the Effect of Parental Participation on Chinese Adolescent Behavioral Development Through the Mediating Effect of Peers: A Moderated Mediation Model.

Background: With the rapid changes in the social environment, adolescents are facing increasing academic pressure and challenges to their physical and mental development in the socialization process. The purpose of this study was to investigate the influence mechanisms of parental participation on adolescent behavioral development (learning persistence, expressive language ability and knowledge absorption ability), revealing the mediation role of adolescent positive and negative peer interactions between parental participation and behavioral development, and whether differences in parents and children's educational expectations moderate this process. Methods: This study was measured using the Parental Participation Questionnaire, Peer Interaction Questionnaire, Behavioral Development Scale, and Educational Expectancy Gap from the China Education Panel Survey. A total of 7730 seventh-grade students and their parents were invited to participate, to establish a moderated mediation model, and the significance of the mediation effect was tested using the bias-corrected percentile Bootstrap method. Results: (1) High frequent parental participation has a significant positive effect on adolescent behavioral development, including behavioral participation, emotional participation, and educational participation all exerting varying degrees of positive influence, as well as positively influencing adolescents' peer interactions. (2) Positive and negative peer interactions play the mediation role of 12.3% and 2.5% respectively in the process of parental participation affecting adolescent behavioral development. (3) Comparing "educational expectation gap - equal", the "educational expectation gap - high" negatively moderates the effect of parental participation on adolescent behavioral development and positive peer interaction (inhibitory effect), the "educational expectation gap - low" positively moderates the effect of parental participation on negative peer interaction (facilitation effect), which meant that the "educational expectation gap - equal" between parents and children is a more desirable state. Conclusion: These findings provide empirical support and effective operational suggestions to further promote positive adolescent behavioral development. Particularly for developing countries, it is recognized that positive parental participation and peer interaction, as well as equal educational expectation of parents and children, are protective factors for adolescent development.

The Importance of Both Individual Differences and Dyadic Processes in Children's Emotion Expression.

Although children display strong individual differences in emotion expression, they also engage in emotional synchrony or reciprocity with interaction partners. To understand this paradox between trait-like and dyadic influences, the goal of the current study was to investigate children's emotion expression using a Social Relations Model (SRM) approach. Playgroups consisting typically of four same-sex unfamiliar nine-year-old children (N = 202) interacted in a round-robin format (6 dyads per group). Each dyad completed two 5-minute tasks, a challenging frustration task and a cooperative planning task. Observers coded children's emotions during the tasks (happy, sad, angry, anxious, neutral) on a second-by-second basis. SRM analyses provided substantial evidence of both the trait-like nature of children's emotion expression (through significant effects for actor variance, multivariate actor-actor correlations, and multivariate intrapersonal correlations) and the dyadic nature of their emotion expression (through significant effects for partner variance, relationship variance, dyadic reciprocity correlations, and multivariate interpersonal correlations).

Modelling the effects of emotional engagement and peer interaction on the continuous intention to use asynchronous e-learning.

Even though asynchronous e-learning has become popular among universities, few studies have examined how students intend to continue using it for their learning. This study proposed a theoretical model that aims to examine the effects of external factors-emotional engagement and peer interaction-and two constructs of technology acceptance model (TAM) on students' continuous intention to use asynchronous e-learning. A total of 259 students participated in a survey. The data were analysed using two steps in SEM AMOS. confirmatory factor analysis was conducted for assessing model measurement, and structural equation modelling was applied for assessing relationships among constructs and testing hypothesis. The results showed that emotional engagement had a significant effect on students' continuous intention to use asynchronous e-learning through the perceived ease of use of asynchronous e-learning and not through its perceived usefulness. Furthermore, peer interaction had a significant effect on students' continuous intention to use asynchronous e-learning. Moreover, the constructs of the technology acceptance model-perceived ease of use and perceived usefulness-had direct and significant effects on students' continuous intention to use asynchronous e-learning. Several implications and suggestions were discussed.

Pathways to peer interaction in ASD and TD through individual and dyadic joint-action motor abilities.

Purpose: Any social engagement, especially with peers, requires children's effective activation of social and motor mechanisms. Children and adolescents with autism spectrum disorder (ASD) often display dysfunctions both in individual motor functioning (e.g., fine/gross) and in dyadic joint action (JA), where two partners coordinate movement toward a shared goal. Yet, these mechanisms' contribution to peer interaction has been underexplored. Method: This study examined the contribution of individual motor functioning and JA performance to peer interaction (cooperation, attentiveness, social engagement, and dyadic quality), while comparing children and adolescents' (youngsters) with ASD versus those with typical development (TD). Results: Results indicated more competent peer interaction in TD than in ASD. Interestingly, only the ASD group showed significant maturation with age for social engagement and dyadic interaction quality, calls for further examination of developmental trajectories. However, even the oldest participants with ASD continued to lag behind the youngest TD group. Also, findings indicated that better individual motor functioning and JA performance explained better peer interactive competence; yet, the contribution of individual motor functioning to social cooperation and dyadic quality was moderated by JA performance. Thus, youngsters' individual motor system was found to be an important contributor to peer interaction in those with low to moderate JA coordination capabilities, but not for those with high JA. Conclusion: Results emphasize possible distinct contributions of each motor mechanism and their interaction for facilitating social interaction, hence, encouraging incorporation of individual and dyadic motor skills explicitly into social interaction interventions for youngsters ASD.

Age differences in interbrain synchronization during peer cooperation: an EEG hyperscanning study.

Healthy peer relationships could provide emotional and social support for adolescents experiencing dramatic physical and environmental changes. Examining age differences in cognitive neural processing during peer interaction provides insight into adolescent interpersonal contact and "social brain" development. The present study compared the age differences between adolescents and adults by examining the behavior and interbrain synchronization of pairs in a cooperative computer game task. 32 pairs of adolescents and 31 pairs of adults were recruited as participants. The reaction times and interbrain synchronization of the participants were measured. The results revealed that interbrain synchronization activation following the onset of the "ready signal" was primarily detected in low-frequency bands such as delta and theta. Adolescent pairs' interbrain synchronization activations were significantly higher than those of adult pairs in the anterior and central brain regions, such as the frontal, frontal-central, and parietal lobes. Correlation analysis indicated a positive correlation between occipital region interbrain synchronization and behavioral performance. The findings provide behavioral and neurophysiological evidence for the characteristics of adolescent interpersonal cognitive processing and point to the significance of low-frequency interbrain synchronization in interpersonal coordination.

Imitation among infants in a day-care center and the development of locomotion.

To examine the relationship between imitation and locomotor development among peers during infancy, we observed free play in a class of infants in a day-care center over a one-year period. The analysis included 16 infants (mean age was 8.3 months (SD=2.3) at the beginning of the observation) and 5 caregivers. The longitudinal data were divided into the crawling, cruising, and walking periods, and the imitation of object manipulation that took place among the infants during each period was analyzed. With the development of locomotion, peer-to-peer imitation became frequent. Infants who had acquired the ability to walk demonstrated imitation more frequently in triadic interactions than in dyadic interactions. Imitation took place between infants, but it was often mediated by caregivers rather than directly between infants. The results suggest that the acquisition of locomotor skills is a link in a developmental cascade from motor development to infant peer interaction. However, it is reasonable to interpret the results as indicating that the development of locomotion does not directly affect infant interactions in isolation, but rather that walking increases both the sharing and manipulation of objects with caregivers and proximity to peers, and their combined effects form a cascade.

Moving Together: Social Motor Synchrony in Autistic Peer Partners Depends on Partner and Activity Type.

Some suggest autistic people display impaired Interpersonal Synchrony. However, partners of different neurotypes can struggle to connect and empathise with one another. We used Motion Energy Analysis to examine Social Motor Synchrony (SMS) in familiar partners of the same neurotype: pairs of autistic and of neurotypical children. Partners played two shared tablet activities, one to support collaboration by facilitating engagement and other-awareness (Connect), and one with no additional design features to facilitate collaboration (Colours). The neurotypical group showed similar SMS to the autistic group in Colours but lower SMS in Connect. The autistic group displayed similar levels of SMS in each activity. Autistic children can synchronise to a similar, or greater, degree than neurotypical children when the social context and type of task are considered.

The impact of adolescent achievement goal orientation on learning anxiety: The mediation effect of peer interaction.

Learning anxiety is one of the most critical emotional disturbances, which also has a high incidence rate in adolescents. Peer interaction is critical and unique for adolescents. Although previous studies have found that achievement goal orientation has an important role in the development of learning anxiety, its mechanism has not been clarified. This study surveyed 470 adolescents (191 middle school students and 279 high school students; 211 boys) and established a structural equation model to explore the mediating role of peer interaction in the influence of achievement goal orientation on learning anxiety. Results showed that (1) there were significant gender differences in mastery-avoidance goal orientation, peer interaction, and learning anxiety, and there were grade differences in performance-approach goal and performance-avoidance goal orientations; (2) mastery-approach, mastery-avoidance, and performance-avoidance goal orientations directly predicted learning anxiety; and (3) social anxiety in peer interactions had a mediating effect on the influence of mastery-approach, mastery-avoidance, and performance-avoidance goal orientations on learning anxiety. The findings extend theoretical considerations by teasing out the process of peer interaction affecting the relationship between achievement goal orientation and learning anxiety. Additionally, the results have practical implications for the effective use of peer interaction to reduce learning anxiety.

Collaborative peer feedback in L2 writing: Affective, behavioral, cognitive, and social engagement.

The recent two decades have witnessed a greater interest in L2 writing research to explore how individual learners engage with and participate in peer feedback. However, not much attention has been directed to peer feedback in the collaborative format, despite the fact that peer collaboration can enable learners to draw on their respective strengths and pool their knowledge. In this qualitative study, we adopted an educational psychological perspective to discover the intricate nature of learners working together to give anonymous feedback to their peers. In addition to learners' cognitive engagement with the correction and revision process, we also investigated learners' affective, behavioral, and social engagement in collaborative peer feedback. The findings show that, although learners can cognitively engage with the task by identifying a number of language-related problems and providing feedback, their affective, behavioral, and social engagement differed considerably. While some participants' engagement was relatively extensive, especially in the affective and social aspect, others' engagement was at a relatively limited level, characterized by negative emotions and low mutuality in peer interaction. The unpleasant task experience affected their attitudes toward collaborative peer feedback activities and their willingness to participate in subsequent tasks.

'Everything turned upside down': A thematic analysis of adolescents' experiences of everyday life during COVID-19 restrictions.

BACKGROUND: At the beginning of the COVID-19 pandemic, people were encouraged to practice social distancing, and schools and leisure venues closed. AIMS: We aimed to explore the everyday experiences of Norwegian adolescents during COVID-19 restrictions, when in-person contact with peers was severely limited. METHODS: A total of 622 high-school students (16-18 years of age) replied to an online survey containing open-ended questions about the changes they experienced in everyday life during the first three months of the pandemic. RESULTS: Reflexive thematic analysis resulted in four themes: (a) 'Everyday life turned upside down - everything is on hold'; (b) 'Alone with my thoughts - new concerns'; (c) 'A loss of social life - a fear of wasting important time'; and (d) 'Gratitude - new perspectives in life'. The results are discussed according to mental-health concerns and psychological developmental challenges during adolescence, such as social exploration of roles with peers, autonomy and identity formation during a crisis. CONCLUSIONS: The results underline individual variations and positive experiences among adolescents during the COVID-19 pandemic, despite social restrictions. Still, the lack of in-person contact with friends is related to an increased experience of loneliness and mental-health concerns for many adolescents.

The impact of moderate physical activity and student interaction on retention at a community college.

Objective: The purpose of this study was to explore the effect of a voluntary walking program that combined moderate physical activity and student interaction on student retention at a community college. Methods: A sample of 69 students at a suburban community college voluntarily joined a walking program and logged the number of minutes they walked and the number of people they spoke to each day. Using a Chi-Squared Test of Independence, the study sample was compared to a matched sample of nonparticipating students. Results: There was a significant difference in these groups relative to retention. A Fisher's Exact Test was used to consider (a) the difference between participants who walked at least 150 minutes per week Reference (1) and those who did not relative to retention and (b) the difference between participants who interacted while walking and those who did not relative to retention. These tests showed no significant differences. Conclusions: Participation in the walking program was significantly associated with retention, but amount of moderate activity or interaction was not.

Predictors of individual differences in minimally verbal peer communication exchanges following peer-oriented social intervention.

School-age children on the autism spectrum who are minimally verbal (MVAS) use a limited repertoire of spontaneous communicative spoken words and reveal large heterogeneity in cognitive functioning. Despite the challenges to form peer social engagement posed by their unique social-communicative profile, few interventions have targeted peer interactions in the MVAS population. This study explored predictors of individual differences in treatment response among 54 school-age minimally verbal autistic children (8-16 years) following an RCT "school-based peer social intervention" (S-PSI) that compared two peer-oriented intervention modalities (conversation versus collaboration) versus a waitlisted control group. We examined autistic-symptom severity, age, verbal and nonverbal IQ, executive functions, and sensory-processing profile for their contribution to children's ability to form relevant spontaneous communication exchanges with a peer partner. Main findings revealed that larger deficits in sensory-processing (sensory-avoidance and sensory low-registration) and in executive functions contributed to greater growth in "relevant" (i.e., adequately attuned, participatory, reciprocal) communication following both interventions, but not for the waitlisted controls. Additionally, older participants with lower verbal and nonverbal IQ improved communication's relevancy more after the conversation intervention, whereas the collaboration intervention was more beneficial for younger participants. Lower autistic-symptom severity contributed to larger growth in relevancy for all groups. By identifying individual-level predictors of spontaneous, attuned, participatory, and reciprocal (i.e., "relevant") communication exchanges with peers, we optimized S-PSI personalization for this uniquely nonverbal, heterogeneous MVAS population. These new channels for tailoring peer interventions to better meet individuals' needs may result in reduced social isolation and loneliness and enhanced well-being.

Social-Motor Coordination Between Peers: Joint Action Developmental Trajectories in ASD and TD.

Coordinating a physical movement in time and space with social and nonsocial partners to achieve a shared goal - "joint action" (JA) - characterizes many peer-engagement situations that pose challenges for individuals with autism spectrum disorder (ASD). This cross-sectional study examined development of JA capabilities comparing ASD versus typically developing (TD) groups in early childhood, preadolescence, and adolescence while performing mirroring and complementing JA tasks with social (peer) and nonsocial (computer) partners. Results indicated better motor coordination abilities on computerized tasks than in peer dyads, with larger peer-dyad deficits shown by the ASD group. Developmental growth in JA abilities emerged, but the ASD group lagged behind same-age peers with TD. Socio-motor interventions may offer new channels to facilitate peer engagement in ASD.

Reciprocity heightens academic performance in elementary school students.

Social relationships are pivotal for human beings. Yet, we still lack a complete understanding of the types and conditions of social relationships that facilitate learning among children. Here, we present the results of a study involving 855 elementary school children from 14 different public schools in Chile designed to understand their social learning strategies in classrooms. We mapped students' social relationships using a behavioral experiment-a non-anonymous social dilemma-that allows us to measure cooperation and infer reciprocal and asymmetrical relationships between peers. We implemented the experiment synchronously in each classroom using networked tablets and a friendly user interface to mitigate cognitive barriers and boost students' engagement. Using regression models, we found a positive and significant association between reciprocity and academic performance. This result holds after controlling for class attendance, sex, parents' education, social status, individual cooperative dispositions, and fixed effects per class group. Finally, using a difference-in-difference framework, we found robust evidence that reciprocity heightens academic performance by comparing two consecutive academic semesters. This effect is heterogeneous and is considerably more prominent for the top 20% students experiencing higher levels of reciprocity in their social relationships. We expect these results to inform cooperative learning interventions in elementary education.

Extending repair in peer interaction: A conversation analytic study.

Peer interaction constitutes a focal site for understanding learning orientations and autonomous learning behaviors. Based on 10 h of video-recorded data collected from small-size conversation-for-learning classes, this study, through the lens of Conversation Analysis, analyzes instances in which L2 learners spontaneously exploit learning opportunities from the on-task public talk and make them relevant for private learning in sequential private peer interaction. The analysis of extended negation-for-meaning practices in peer interaction displays how L2 learners orient to public repair for their learning opportunities in an immediate manner and in so doing, how different participation framework is being utilized to maximize their learning outcomes. As these extended repair practices are entirely managed by learners themselves, they yield both efficient and inefficient learning outcomes. Findings reveal that learners frequently resort to their peers to recycle the focal trouble words for learning opportunities, shifting their participating role from the on looking audience to active learners. By reporting the rather under-researched post-repair negotiation-for-meaning sequence in peer interactions, the study highlights the relevance between on-task classroom activities and private learning, contributing to understanding private learning behaviors in the language classroom and learning as a co-constructed activity locally situated in peer interaction.

Impacts of family environment on adolescents' academic achievement: The role of peer interaction quality and educational expectation gap.

The current study uses a two-wave longitudinal survey to explores the influence mechanism of the family environment on adolescents' academic achievement. The family environment is measured by parents and children's reports, including family atmosphere, parent-child interaction, and family rules, to reveal the mediating effect of adolescents' positive or negative peers between the family environment and academic achievement, and whether the gap between self- and parental educational expectation plays a moderating effect. This study uses the data of the China Education Panel Study (CEPS); the survey samples include 9,449 eighth-grade students (Mage = 13.55 years, SD = 0.70), establishing a multilevel moderated mediating effect model. The results showed (1) the family environment and peer interaction quality can positively predict adolescents' academic achievement. (2) Using the KHB test, peer interaction quality plays a partial mediating role in the process of family environment positively affecting academic achievement, and the mediating ratio is 27.5%. (3) The educational expectation gap moderates the effect of the family environment on academic achievement and also on peer interaction quality. Therefore, from the perspective of environment and important others, to correctly grasp the academic achievement of junior high school students in the process of socialization, it is necessary to recognize that the family environment, peer interaction quality, and educational expectation gap play an important role.

The impact of attitude toward peer interaction on middle school students' problem-solving self-efficacy during the COVID-19 pandemic.

The outbreak of the COVID-19 epidemic has promoted the popularity of online learning, but has also exposed some problems, such as a lack of interaction, resulting in loneliness. Against this background, students' attitudes toward peer interaction may have become even more important. In order to explore the impact of attitude toward peer interaction on students' mindset including online learning motivation and critical thinking practice that could affect their problem-solving self-efficacy during the COVID-19 pandemic, we developed and administered a questionnaire, receiving 1,596 valid responses. The reliability and validity of the questionnaire were re-tested, and structural equation modeling was applied. It was found that attitude toward peer interaction could positively predict middle school students' online learning motivation and critical thinking. Learning motivation and critical thinking also positively supported problem-solving self-efficacy. It is expected that the results of this study can be a reference for teachers to adopt student-centered online learning in problem solving courses.

Influence of pretesting and a near peer sharing real life experiences on CPR training outcomes in first year medical students: a non-randomized quasi-experimental study.

BACKGROUND: Existing literature on cardiopulmonary resuscitation (CPR) training focuses on the knowledge and skill components while the attitudinal component is rarely addressed. There is a need to explore how peer interaction, learning atmosphere, and communication influence learning effectiveness during CPR training. Therefore, this study's objective was to evaluate how a senior student (near peer) sharing their real-life experience of performing CPR would influence medical students' learning and readiness to perform CPR. METHODS: The present study involved 250 newly enrolled undergraduate medical students. The Solomon's four-group study design was used to evaluate the influence of both pretesting and peer interaction. Students belonging to two groups initially completed a pre-training knowledge test (pretest) and a questionnaire on readiness to perform CPR. Students from all four groups then participated in instructor-led hands-on skills training, after which the two intervention groups interacted with their senior, who shared their life experiences of performing CPR. Finally, all four groups underwent skills evaluation, immediate and delayed post-tests, and completed a questionnaire to assess readiness to perform CPR. The students also provided their feedback on the experience of interacting with a peer during the training. RESULTS: Post-test scores were significantly higher than pretest scores (Kruskal-Wallis test, p < 0.05). Scores were significantly higher in pretested intervention groups than in the non-pretested non-intervention group (p < 0.05). Delayed post-test scores were slightly but not significantly lower than the immediate post-test scores with no significant difference observed in the scores among the groups. The pretested groups showed more readiness to perform CPR and the pretested intervention group were least concerned about acquiring infection during CPR. Students in all groups were confident of performing chest compressions correctly, and found it inspiring and motivating listening to and discussing real-life experiences with a near peer. CONCLUSIONS: Hearing from peers about real-life CPR experience during CPR training sessions significantly impacted learning, enhanced student motivation to learn and may be an effective strategy to consider in routine CPR training. However, the positive effects of pretesting and peer interaction on knowledge were not sustained, highlighting a need for repeat training.
