While numerous neuroimaging studies have investigated executive circuits as putative neural substrates of repetitive behavior, recent work implicates affective neural circuits in restricted interests. We sought to explore the role of affective neural circuits and determine how restricted interests are distinguished from hobbies or interests in typical development. Methods We compared a group of children with ASD to a typically developing (TD) group of children with strong interests or hobbies, employing parent report, an operant behavioral task, and functional imaging with personalized stimuli based on individual interests. Results While performance on the operant task was similar between the two groups, parent report of intensity and interference of interests was significantly higher in the ASD group. Both the ASD and TD groups showed increased BOLD response in widespread affective neural regions to the pictures of their own interest. When viewing pictures of other children's interests, the TD group showed a similar pattern, whereas BOLD response in the ASD group was much more limited. Increased BOLD response in the insula and anterior cingulate cortex distinguished the ASD from the TD group, and parent report of the intensity and interference with daily life of the child's restricted interest predicted insula response. Conclusions While affective neural network response and operant behavior are comparable in typical and restricted interests, the narrowness of focus that clinically distinguishes restricted interests in ASD is reflected in more interference in daily life and aberrantly enhanced insula and anterior cingulate response to individuals’ own interests in the ASD group. These results further support the involvement of affective neural networks in repetitive behaviors in ASD.

Biobehavioral profiles of arousal and social motivation in autism spectrum disorders / Blythe A. CORBETT in Journal of Child Psychology and Psychiatry, 55-8 (August 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-8 (August 2014) . - p.924-934 Titre : Biobehavioral profiles of arousal and social motivation in autism spectrum disorders Type de document : texte imprimé Auteurs : Blythe A.

NEWSOM, Auteur ; Lily WANG, Auteur ; Yanna SONG, Auteur ; Dale EDGERTON, Auteur Article en page(s) : p.924-934 Langues : Anglais (eng) Mots-clés : Autism  cortisol  play  stress  social  interaction  behavior Index. décimale : PER Périodiques Résumé : Background Children with autism spectrum disorder (ASD) are impaired in social communication and interaction with peers, which may reflect diminished social motivation. Many children with ASD show enhanced stress when playing with other children. This study investigated social and stress profiles of children with ASD during play. Methods We utilized a peer interaction paradigm in a natural playground setting with 66 unmedicated, prepubertal, children aged 8–12 years [38 with ASD, 28 with typical development (TD)]. Salivary cortisol was collected before and after a 20-min playground interaction that was divided into periods of free and solicited play facilitated by a confederate child. Statistical analyses included Wilcoxon rank-sum tests, mixed effects models, and Spearman correlations to assess the between-group differences in social and stress functioning, identify stress responders, and explore associations between variables, respectively. Results There were no differences between the groups during unsolicited free play; however, during solicited play by the confederate, significant differences emerged such that children with ASD engaged in fewer verbal interactions and more self-play than the TD group. Regarding physiological arousal, children with ASD as a group showed relatively higher cortisol in response to social play; however, there was a broad range of responses. Moreover, those with the highest cortisol levels engaged in less social communication. Conclusions The social interaction of children with ASD can be facilitated by peer solicitation; however, it may be accompanied by increased stress. The children with ASD that have the highest level of cortisol show less social motivation; yet, it is unclear if it reflects an underlying state of heightened arousal or enhanced reactivity to social engagement, or both.

Brief report: Service implementation and maternal distress surrounding evaluation recommendations for young children diagnosed with autism / Zachary WARREN in Autism, 17-6 (November 2013)  

Public ISBD [article]  inAutism > 17-6 (November 2013) . - p.693-700 Titre : Brief report: Service implementation and maternal distress surrounding evaluation recommendations for young children diagnosed with autism Type de document : texte imprimé Auteurs : Zachary WARREN, Auteur ; Alison VEHORN, Auteur ; Elizabeth DOHRMANN, Auteur ; Cassandra R.

The distress a family may encounter with regard to inability to access recommended services is also poorly understood. In this study, we present preliminary data regarding implementation of clinical recommendations following autism spectrum disorder diagnosis as well as associations of implementation with maternal functioning. In total, 75 mothers of young children diagnosed with autism spectrum disorder through a university-based preschool autism clinic returned surveys regarding access to recommended services as well as maternal mental health and distress. Results indicate that while families were able to implement numerous recommendations, specific categories of intervention were less likely to be received. Challenges implementing recommended services were not related to increased maternal distress. These results suggest that despite potential barriers toward accessing some specific recommended services following diagnosis of autism spectrum disorder, many families may be quite successful in implementing many other core recommended services and that failure to access such services may not necessarily negatively impact maternal mental health and distress.

Studying the predictors of DKCC growth in young children with ASD might inform treatment of this under-studied aspect of prelinguistic development. Eighty-seven initially preverbal preschoolers with ASD and their parents were observed at five measurement periods. In this longitudinal correlational investigation, we found that child intentional communication acts and parent linguistic responses to child leads predicted DKCC growth, after controlling for two other predictors and two background variables. As predicted, receptive vocabulary mediated the association between the value-added predictors and endpoint DKCC.

Examining the relationship between face processing and social interaction behavior in children with and without autism spectrum disorder / Blythe A. CORBETT in Journal of Neurodevelopmental Disorders, 6-1 (December 2014)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 6-1 (December 2014) . - p.35 Titre : Examining the relationship between face processing and social interaction behavior in children with and without autism spectrum disorder Type de document : texte imprimé Auteurs : Blythe A. CORBETT, Auteur ; Cassandra R. NEWSOM, Auteur ; Alexandra P. KEY, Auteur ; Lydia R. QUALLS, Auteur ; E. Kale EDMISTON, Auteur Article en page(s) : p.35 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Ecological validity  Face memory  Neuropsychology  Play Index. décimale : PER Périodiques Résumé : BACKGROUND: Children with autism spectrum disorder (ASD) show impairment in reciprocal social communication, which includes deficits in social cognition and behavior. Since social cognition and social behavior are considered to be interdependent, it is valuable to examine social processes on multiple levels of analysis. Neuropsychological measures of face processing often reveal deficits in social cognition in ASD including the ability to identify and remember facial information. However, the extent to which neuropsychological measures are associated with or predictive of real-world social behavior is unclear. METHODS: The study investigated 66 children (ASD 34, typically developing (TD) 32) using neuropsychological measures of face processing (identity, affect, and memory). Children also participated in a peer interaction paradigm, which allowed observation and coding of natural social interaction behaviors during play with peers (e.g., Self-Play, Cooperative Play, Verbal Bout). ANCOVA, regression, and correlation models analyzed between-group differences, the ability of neuropsychological measures to predict social behavior, and the strength of the associations. RESULTS: Between-group differences were shown on Memory for Faces Delayed and the peer interaction variables Self-Play and Verbal Bout. Regression models indicated that Memory for Faces Delayed predicted the amount of Self-Play, Equipment use alone, and Cooperative Play with peers on the playground. Autism symptomology only predicted verbal exchange with peers. CONCLUSIONS: Face memory strongly predicts relevant social engagement patterns in both children with and without ASD. Impairment in facial memory is associated with reduced 'real-world' social interaction and more self-play, whereas higher performance in face memory predicts more cooperative play. Results highlight the strong connection between face memory and reciprocal social interaction, suggesting that improvement in one may benefit the other.
