Predicting Social Competence in Autistic and Non-Autistic Children: Effects of Prosody and the Amount of Speech Input.

PURPOSE: Autistic individuals often face challenges perceiving and expressing emotions, potentially stemming from differences in speech prosody. Here we explore how autism diagnoses between groups, and measures of social competence within groups may be related to, first, children's speech characteristics (both prosodic features and amount of spontaneous speech), and second, to these two factors in mothers' speech to their children. METHODS: Autistic (n = 21) and non-autistic (n = 18) children, aged 7-12 years, participated in a Lego-building task with their mothers, while conversational speech was recorded. Mean F0, pitch range, pitch variability, and amount of spontaneous speech were calculated for each child and their mother. RESULTS: The results indicated no differences in speech characteristics across autistic and non-autistic children, or across their mothers, suggesting that conversational context may have large effects on whether differences between autistic and non-autistic populations are found. However, variability in social competence within the group of non-autistic children (but not within autistic children) was predictive of children's mean F0, pitch range and pitch variability. The amount of spontaneous speech produced by mothers (but not their prosody) predicted their autistic children's social competence, which may suggest a heightened impact of scaffolding for mothers of autistic children. CONCLUSION: Together, results suggest complex interactions between context, social competence, and adaptive parenting strategies in driving prosodic differences in children's speech.

The Contribution of Perceptual Reasoning Skills to Phonological Awareness for School Age Autistic Children.

This study aimed to investigate the phonological awareness (PA) skills of school age autistic children (age range = 6-12) in two parts: (1) comparing their performance on a PA task to non-autistic children with groups matched on chronological age, verbal and non-verbal cognitive skills, and (2) exploring the role of cognitive skills and autism characteristics on PA skills. Results revealed that the groups did not differ in their PA skills (study 1) and that perceptual reasoning skills are associated with the PA skills of autistic participants (study 2). Results highlight the role of non-verbal cognitive skills in literacy development for autistic children and suggest that their perceptual reasoning abilities likely contribute a great deal when learning to read.

Negative first impression judgements of autistic children by non-autistic adults.

Introduction: Although autism inclusion and acceptance has increased in recent years, autistic people continue to face stigmatization, exclusion, and victimization. Based on brief 10-second videos, non-autistic adults rate autistic adults less favourably than they rate non-autistic adults in terms of traits and behavioural intentions. In the current study, we extended this paradigm to investigate the first impressions of autistic and non-autistic children by non-autistic adult raters and examined the relationship between the rater's own characteristics and bias against autistic children. Method: Segments of video recorded interviews from 15 autistic and 15 non-autistic children were shown to 346 undergraduate students in audio with video, audio only, video only, transcript, or still image conditions. Participants rated each child on a series of traits and behavioural intentions toward the child, and then completed a series of questionnaires measuring their own social competence, autistic traits, quantity and quality of past experiences with autistic people, and explicit autism stigma. Results: Overall, autistic children were rated more negatively than non-autistic children, particularly in conditions containing audio. Raters with higher social competence and explicit autism stigma rated autistic children more negatively, whereas raters with more autistic traits and more positive past experiences with autistic people rated autistic children more positively. Discussion: These rapid negative judgments may contribute to the social exclusion experienced by autistic children. The findings indicate that certain personal characteristics may be related to more stigmatised views of autism and decreased willingness to interact with the autistic person. The implications of the findings are discussed in relation to the social inclusion and well-being of autistic people.

Atypical Associations between Functional Connectivity during Pragmatic and Semantic Language Processing and Cognitive Abilities in Children with Autism.

Autism Spectrum Disorder (ASD) is characterized by both atypical functional brain connectivity and cognitive challenges across multiple cognitive domains. The relationship between task-dependent brain connectivity and cognitive abilities, however, remains poorly understood. In this study, children with ASD and their typically developing (TD) peers engaged in semantic and pragmatic language tasks while their task-dependent brain connectivity was mapped and compared. A multivariate statistical approach revealed associations between connectivity and psychometric assessments of relevant cognitive abilities. While both groups exhibited brain-behavior correlations, the nature of these associations diverged, particularly in the directionality of overall correlations across various psychometric categories. Specifically, greater disparities in functional connectivity between the groups were linked to larger differences in Autism Questionnaire, BRIEF, MSCS, and SRS-2 scores but smaller differences in WASI, pragmatic language, and Theory of Mind scores. Our findings suggest that children with ASD utilize distinct neural communication patterns for language processing. Although networks recruited by children with ASD may appear less efficient than those typically engaged, they could serve as compensatory mechanisms for potential disruptions in conventional brain networks.

Are people with autism prosopagnosic?

Difficulties in various face processing tasks have been well documented in autism spectrum disorder (ASD). Several meta-analyses and numerous case-control studies have indicated that this population experiences a moderate degree of impairment, with a small percentage of studies failing to detect any impairment. One possible account of this mixed pattern of findings is heterogeneity in face processing abilities stemming from the presence of a subpopulation of prosopagnosic individuals with ASD alongside those with normal face processing skills. Samples randomly drawn from such a population, especially relatively smaller ones, would vary in the proportion of participants with prosopagnosia, resulting in a wide range of group-level deficits from mild (or none) to severe across studies. We test this prosopagnosic subpopulation hypothesis by examining three groups of participants: adults with ASD, adults with developmental prosopagnosia (DP), and a comparison group. Our results show that the prosopagnosic subpopulation hypothesis does not account for the face impairments in the broader autism spectrum. ASD observers show a continuous and graded, rather than categorical, heterogeneity that span a range of face processing skills including many with mild to moderate deficits, inconsistent with a prosopagnosic subtype account. We suggest that pathogenic origins of face deficits for at least some with ASD differ from those of DP.

A new acquisition protocol for conducting studies with children: The science camp research experience.

In the last 50 years, the study of brain development has brought major discoveries to education and medicine, changing the lives of millions of children and families. However, collecting behavioral and neurophysiological data from children has specific challenges, such as high rates of data loss and participant dropout. We have developed a science camp method to collect data from children using the benefits of positive peer interactions and interactive and engaging activities, to allow researchers to better collect data repeatedly and reliably from groups of children. A key advantage of this approach is that by increasing participant engagement, attention is also increased, thereby increasing data quality, reducing data loss, and lowering attrition rates. This protocol describes the step-by-step procedure for facilitation of a science camp, including behavioral, electrophysiological, and participatory engagement activities. As this method is robust but also flexible, we anticipate that it can also be applied to different demographics and research needs.

Examining the Relations Between Social Competence, Autistic Traits, Anxiety and Depression in Autistic and Non-Autistic Children.

The current study examined whether social competence and autistic traits are related to anxiety and depression in autistic and non-autistic children. Parents of 340 children aged 6 to 12 years old, including 186 autistic and 154 non-autistic children completed the Autism Spectrum Quotient (AQ) to assess their child's autistic traits, the Multidimensional Social Competence Scale (MSCS) to assess their child's social competence, and the Behaviour Assessment Scale for Children 2 (BASC-2) to assess their child's internalizing symptoms of depression and anxiety, and children were administered the Wechsler Abbreviated Scale of Intelligence, Second Edition (WASI-II) to assess their intellectual abilities. Hierarchical multiple regression analyses were conducted to investigate the relations between social competence, autistic traits, anxiety, and depression. Social competence was related to anxiety and depression symptoms in autistic children, but only depression symptoms in non-autistic children, above and beyond the effects of autistic traits, IQ and age. Autistic children were also reported to experience more severe anxiety and depression symptoms, and more autistic traits were related to higher levels of anxiety and depression in both groups. These findings suggest that social competence and internalizing symptoms are intricately connected in autistic children and need to be jointly considered in both assessment and intervention. The social implications are discussed with an emphasis on acceptance of diverse social styles as a viable avenue to reduce children's internalizing symptoms.

Exogenous oxytocin administration during labor and autism spectrum disorder.

BACKGROUND: Oxytocin is a neuropeptide hormone that plays a key role in social behavior, stress regulation, and mental health. Synthetic oxytocin administration is a common obstetrical practice, and importantly, previous research has suggested that intrapartum exposure may increase the risk of neurodevelopmental disorders, such as autism spectrum disorder. OBJECTIVE: This study aimed to examine the association between synthetic oxytocin exposure during labor and autism spectrum disorder diagnosis in the child. STUDY DESIGN: This population-based retrospective cohort study compared 2 cohorts of children: (1) all children born in British Columbia, Canada between April 1, 2000 and December 31, 2014 (n=414,336 births), and (2) all children delivered at Soroka University Medical Center in Be'er-Sheva, Israel between January 1, 2011 and December 31, 2019 (n=82,892 births). Nine different exposure groups were examined. Cox proportional hazards models were used to estimate crude and adjusted hazard ratios of autism spectrum disorder in both cohorts on the basis of induction and/or augmentation exposure status. To further control for confounding by indication, we conducted sensitivity analyses among a cohort of healthy, uncomplicated deliveries and among a group that was induced only for postdates. In addition, we stratified our analyses by infant sex to assess for potential sex differences. RESULTS: In the British Columbia cohort, 170,013 of 414,336 deliveries (41.0%) were not induced or augmented, 107,543 (26.0%) were exposed to oxytocin, and 136,780 (33.0%) were induced or augmented but not exposed to oxytocin. In the Israel cohort, 51,790 of 82,892 deliveries (62.5%) were not induced or augmented, 28,852 (34.8%) were exposed to oxytocin, and 2250 (2.7%) were induced or augmented but not exposed to oxytocin. On adjusting for covariates in the main analysis, significant associations were observed in the Israel cohort, including adjusted hazard ratios of 1.51 (95% confidence interval, 1.20-1.90) for oxytocin-augmented births and 2.18 (95% confidence interval, 1.32-3.57) for those induced by means other than oxytocin and not augmented. However, oxytocin induction was not significantly associated with autism spectrum disorder in the Israel cohort. In the Canadian cohort, there were no statistically significant adjusted hazard ratios. Further, no significant sex differences were observed in the fully adjusted models. CONCLUSION: This study supports that induction of labor through oxytocin administration does not increase the risk of autism spectrum disorder in the child. Our international comparison of 2 countries with differences in clinical practice regarding oxytocin administration for induction and/or augmentation suggests that previous studies reporting a significant association were likely confounded by the underlying indication for the induction.

A preliminary exploration of different coping strategies used by Korean immigrant parents of autistic children in high versus low family quality of life ratings.

LAY ABSTRACT: The experiences of coping in parents of autistic children have been extensively studied in the literature. While this research has identified both effective and ineffective coping strategies used by caregivers, no studies to date have examined how coping strategies used by parents might be linked to family quality of life outcomes. Furthermore, few studies exist examining both coping strategies and family quality of life in culturally and linguistically diverse populations. Thus, this study aimed to address both limitations. A total of 12 Korean immigrant parents of autistic children, 6 representing the high family quality of life group and 6 representing the low family quality of life group, shared their experiences related to coping and managing stress. Responses fell under three broad categories (problem-focused, emotion-focused, and adjustment-focused) with differences observed when comparing the high versus low family quality of life groups. A better understanding of the link between coping strategies and family quality of life outcomes may help identify effective and culturally sensitive supports for caregivers and families to improve their quality of life and well-being.

Brief Report: Alexithymia Trait Severity, Not Autistic Trait Severity, Relates to Caregiver Reactions to Autistic Children's Negative Emotions.

Alexithymia impacts an individual's ability to recognize and understand emotions and frequently co-occurs with autism. This study investigated the relationship between children's alexithymia, autistic traits, and caregiver reactions to their child's negative emotions. Caregivers of 54 autistic and 51 non-autistic children between the ages of 7 and 12 years rated their child's alexithymia and autistic trait severity and their reactions to their child's negative emotions. Caregivers of autistic children reported greater supportive reactions and fewer restrictive/controlling reactions to their child's negative emotions when their child had more alexithymia traits. This study extends previous research by demonstrating that caregivers of autistic children with co-occurring alexithymia traits represent a specific subgroup of caregivers that respond more positively to their child's negative emotions.

Facilitators and Barriers to Physical Activity Involvement as Described by Autistic Youth with Mild Intellectual Disability.

Objectives: Physical activity involvement among autistic youth and youth with an intellectual disability is significantly lower than the general population. Few studies have included youth with comorbid diagnoses of ASD and intellectual disability. Fewer studies collect information from the youth themselves. This study examined barriers and facilitators to physical activity in autistic youth with mild intellectual disability using semi-structured interviews with youth and through caregiver reports. Methods: Fourteen caregivers and their children ages 8 to 16 years old participated. Caregivers completed a questionnaire about their thoughts on their child's physical activity while their children completed the semi-structured interview. A descriptive phenomenological approach was followed. Results: Four themes were inductively identified: intrapersonal barriers (factors that are within the person which impede physical activity involvement, such as exhibiting challenging behaviors that inhibit engagement), interpersonal barriers (factors external to the person, such as lack of community support), intrapersonal facilitators (factors within the person that enhance physical activity involvement, such as being intrinsically motivated to improve skills), and interpersonal facilitators (external factors such as supports from caregivers). Conclusions: Interviewing youth is important to capture a holistic picture of factors influencing physical activity. Future research may focus on implementing and assessing the efficacy of strategies to address the barriers facing youth diagnosed with ASD and intellectual disability.

Children with autism spectrum disorder show atypical electroencephalographic response to processing contextual incongruencies.

Children with autism spectrum disorder (ASD) experience difficulties with social communication, making it challenging to interpret contextual information that aids in accurately interpreting language. To investigate how the brain processes the contextual information and how this is different in ASD, we compared event-related potentials (ERPs) in response to processing visual and auditory congruent and incongruent information. Two groups of children participated in the study: 37 typically developing children and 15 children with ASD (age range = 6 to 12). We applied a language task involving auditory sentences describing congruent or incongruent images. We investigated two ERP components associated with language processing: the N400 and P600. Our results showed how children with ASD present significant differences in their neural responses in comparison with the TD group, even when their reaction times and correct trials are not significantly different from the TD group.

Effects of an Educational Presentation About Autism on High School Students' Perceptions of Autistic Adults.

Background: Social communication difficulties are a clinical characteristic of autism, but social interactions are reciprocal in nature and autistic individuals' social abilities may not be the only factor influencing their social success. Nonautistic individuals' social perceptions and behavior also contribute to autistic individuals' social difficulties. Previous research has identified that nonautistic individuals' perception of autistic individuals is influenced by autism knowledge and the quantity and quality of exposure to autistic people. The current research aimed to examine how autistic adults are perceived by high school students, assess whether quality and quantity of autism contact predicts these perceptions, and explore whether these perceptions are malleable. Methods: One hundred fifty-one senior high school students (15-19 years old) completed the First Impression Scale after viewing video recordings of 20 autistic and 20 nonautistic adults in social situations, either before or after viewing a 50-minute educational presentation detailing the everyday experiences of autistic people and participating in a question-and-answer session. We assessed students' prior experiences with autistic people using the Quantity and Quality of Contact Scale and their own self-perceived social competence using the Multidimensional Social Competence Scale. Results: Consistent with previous studies, students rated autistic adults less favorably than nonautistic adults. However, the educational presentation produced modest but significant improvements on these ratings, with students who viewed the presentation rating autistic adults as more attractive and likable and reporting greater social interest in them compared to those who had not yet viewed the presentation. Furthermore, consistent with a double empathy framework, exploratory analyses indicated that self-reports of greater social competence among students was associated with greater bias against autistic adults, whereas reports of higher quality interactions with autistic people were associated with less bias. Conclusion: Previous research has demonstrated that nonautistic adults evaluate autistic people less favorably and report lower social interest in them relative to nonautistic controls. In this study, we extend these findings to adolescents but find these biases are somewhat malleable, with education about autism exerting some modest benefits. Changing nonautistic attitudes about autistic differences may provide an avenue for improving interactions for autistic individuals without putting the onus on autistic individuals to change or mask their behavior and identity.

Why is this an important issue?: Nonautistic people often have negative views or biases about autistic differences. These biases contribute to the "Double Empathy Problem," where the attitudes, misunderstandings, and behaviors of nonautistic people can add to the social challenges faced by autistic people. However, we do not know how and why these negative biases develop, and more research is needed to understand when they appear, what factors contribute to them, and whether they can be changed. What was the purpose of this study?: We wanted to look at whether nonautistic teenagers at high school share the same biases toward autistic people that have previously been shown in adults. We then wanted to see if we could improve nonautistic teenagers' views of autistic people by teaching them about what being autistic means. We were also curious whether high school students who have spent more time with autistic people would view autistic people more positively. Finally, we were interested in whether nonautistic people's views of autistic people depend on how they viewed their own social skills. What did the researchers do?: High school students (15­19 years old) viewed an educational presentation describing the everyday experiences of autistic people and took part in a question-and-answer session about autism. They also made judgments about 20 autistic and 20 nonautistic adults in videos, such as whether they thought the person in the video was likable or awkward, and if they would hang out with them or not. Half of the students made these judgments before viewing the presentation and the other half did this after viewing the presentation. This allowed us to see whether the educational presentation could change high school students' attitudes about autistic people. The high school students also filled out questionnaires about their experiences with autistic people and their own social skills, so we could assess whether these things were associated with attitudes about autistic people. What were the results of this study?: Students viewing the educational presentation first rated autistic adults as more attractive, likable, and said they would be more interested in hanging out with them compared with the students who had not yet viewed the presentation. Students who reported higher quality experiences with autistic people in the past judged autistic people in the videos more positively, but those who thought they personally had strong social skills judged the autistic adults more negatively. What do these findings add to what was already known?: We previously knew that nonautistic adults have negative attitudes toward autistic people. In this study, we show that nonautistic high school students also show negative attitudes toward autistic people. More importantly, we also find that these views can be improved somewhat by a presentation about autism. We also show that nonautistic adolescents who say they are the most socially skilled rate autistic people the most negatively. This may be because they are the most likely to value "typical" or "normative" social skills and be more judgmental about those who socialize in a different way. What are the potential weaknesses in the study?: Students only rated autistic people from videos. We are not sure if the results would have been the same if the students were judging autistic people in real life or directly interacting with them. We also do not know if the judgments would be different if we had used different autistic adults or a more diverse sample. For instance, none of the autistic adults in the videos had an intellectual disability. How will these findings help autistic adults now or in the future?: These findings suggest that educating about autistic lives and high-quality contact with autistic people may be tools for improving the attitudes of nonautistic adolescents. This stage in life may be particularly important for improving the acceptance and inclusion of autistic people, as late adolescence is when many autistic people are beginning the transition to adulthood and their well-being may be increasingly affected by their experiences with nonautistic people.

A community-engaged approach to examining barriers and facilitators to accessing autism services in Korean immigrant families.

LAY ABSTRACT: Perceptions and experiences of culturally and linguistically diverse groups in accessing autism services in Canada are extremely limited. Thus, this study partnered with a community member to explore Korean immigrant parents' perceptions of barriers and facilitators to accessing autism services in British Columbia, Canada. Interviews were conducted with 20 Korean parents of autistic children. Barriers and facilitators at the system, provider, and family/cultural level were identified. Barriers at the system level included delays and waitlists for services, and ineffective school policies to address child behavioral challenges. At the provider level, barriers included a lack of qualified professionals, negative attitudes, and lack of guidance navigating services. For family/cultural-related barriers, these included language and communication difficulties, out-of-pocket costs, and stigma impeded service access. Facilitators at the system level included family-centered care and prioritization of mental health supports. At the provider level, strengths included culturally competent and bilingual professionals. The family/cultural-related facilitators identified were informal support networks, characteristics of the parent, and connections to cultural community organizations. The findings emphasize the need to understand and consider diverse experiences, preferences, and values in the design and provision of autism services for families and their children.

Family Experiences of Decreased Sound Tolerance in ASD.

Decreased sound tolerance (DST) is the most common sensory difficulty experienced by autistic individuals. Parents of 88 autistic children and young adults between the ages of 3 and 30 described coping strategies and physical and emotional responses used to deal with distressing sounds, and their impact on daily activities. Loud, sudden, and high-pitched sounds were most commonly endorsed as distressing, most often causing autistic children and young adults to cover their ears or yell, while producing stress, irritation, fear, and anxiety. Parents reported warning their child, providing breaks, or avoiding noisy settings as the most used coping strategies. Overall, findings indicate that DST leads to fewer opportunities for autistic children and young adults to participate at home, at school, and in the community. Further, results suggest hyperacusis, misophonia, and phonophobia, subtypes of DST, are present in autistic children and young adults.

Attention capture by trains and faces in children with and without autism spectrum disorder.

This study examined involuntary capture of attention, overt attention, and stimulus valence and arousal ratings, all factors that can contribute to potential attentional biases to face and train objects in children with and without autism spectrum disorder (ASD). In the visual domain, faces are particularly captivating, and are thought to have a 'special status' in the attentional system. Research suggests that similar attentional biases may exist for other objects of expertise (e.g. birds for bird experts), providing support for the role of exposure in attention prioritization. Autistic individuals often have circumscribed interests around certain classes of objects, such as trains, that are related to vehicles and mechanical systems. This research aimed to determine whether this propensity in autistic individuals leads to stronger attention capture by trains, and perhaps weaker attention capture by faces, than what would be expected in non-autistic children. In Experiment 1, autistic children (6-14 years old) and age- and IQ-matched non-autistic children performed a visual search task where they manually indicated whether a target butterfly appeared amongst an array of face, train, and neutral distractors while their eye-movements were tracked. Autistic children were no less susceptible to attention capture by faces than non-autistic children. Overall, for both groups, trains captured attention more strongly than face stimuli and, trains had a larger effect on overt attention to the target stimuli, relative to face distractors. In Experiment 2, a new group of children (autistic and non-autistic) rated train stimuli as more interesting and exciting than the face stimuli, with no differences between groups. These results suggest that: (1) other objects (trains) can capture attention in a similar manner as faces, in both autistic and non-autistic children (2) attention capture is driven partly by voluntary attentional processes related to personal interest or affective responses to the stimuli.

The science of humanity and the humanity of science: Perspectives on Ed Zigler's contributions to developmental psychopathology and the study of all children.

We present this article as a testament to Ed Zigler's commitment to science in the service of humanity and to policy based on conceptually compelling theory and methodologically rigorous science. In doing so, we highlight ways that Ed's universal and inclusive developmental world view, early training as a behaviorist, exacting scientific standards, concern for others, and appreciation of his own roots and upbringing all transformed the way that many different groups of people of all ages and backgrounds are studied, viewed, and intervened with by researchers, policy makers, and society at large. Ed's narrative of development rather than defect, universality rather than difference, and holistic rather than reductionist continues to compel us in the quest for a kinder, more inclusive, and enabling society. Conversely, Ed's behaviorist training as a graduate student also influenced him throughout his career and was essential to his career-long commitment to systemic action in the service of improving the lives of others. We cite the lessons that we, as his descendants, learned from Ed and apply them to our own areas of research with populations that Ed did not study, but had considerable interest in - persons with autism spectrum disorder and Indigenous youth.

Alexithymia is related to poor social competence in autistic and nonautistic children.

Alexithymia is characterized by difficulties identifying and describing one's own emotions and the emotions of others. These challenges with understanding emotions in people with alexithymia may give rise to difficulties with social interactions. Given that alexithymia frequently co-occurs with autism spectrum disorder (ASD), and that both populations have difficulties with social interactions, it is of interest to determine whether alexithymia can help to parse some of the heterogeneity in social competence in autistic and nonautistic individuals. The caregivers of 241 children (6-14 years old), including 120 autistic, and 121 nonautistic, rated their child's social competence using the Multidimensional Social Competence Scale (MSCS), autism traits using the Autism Spectrum Quotient (AQ), and alexithymia traits using the Children's Alexithymia Measure (CAM). Regression analyses indicated that age, IQ, sex, AQ, and CAM scores accounted for 40.2% of the variance in autistic children's, and 68.2% of the variance in nonautistic children's, parent-reported social competence. Importantly, after controlling for age, IQ, sex, and AQ scores, CAM scores alone accounted for an additional 16.2% of the variance in autistic children's, and 17.4% of the variance in nonautistic children's social competence. These results indicate that higher alexithymia traits predict lower levels of social competence, suggesting that increased difficulty in identifying and describing one's own emotions and the emotions of others is associated with poorer social competence. Furthermore, CAM scores were found to partially mediate the relationship between autistic traits and social competence, suggesting that comorbid alexithymia traits may be partially responsible for poor social competence in individuals with high autistic traits. This research contributes to the understanding of the factors associated with the development of social competence and highlights alexithymia as a potential target for identification and intervention to improve social competence. LAY SUMMARY: Alexithymia is a condition where people find it hard to think and talk about their (and others') feelings. About 50% of autistic people have alexithymia. This might be why they have social and emotional difficulties. Parents answered questions about alexithymia and social difficulties their children have. Children with more alexithymia problems had poorer social skills. Thus, alexithymia may be related to social problems faced by autistic and nonautistic children.
