Conflict adaptation and congruency sequence effects to social–emotional stimuli in individuals with autism spectrum disorders / Whitney WORSHAM in Autism, 19-8 (November 2015)  

Public ISBD [article]  inAutism > 19-8 (November 2015) . - p.897-905 Titre : Conflict adaptation and congruency sequence effects to social–emotional stimuli in individuals with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Whitney WORSHAM, Auteur ; Whitney E. GRAY, Auteur ; Michael J. LARSON, Auteur ; Mikle SOUTH, Auteur Article en page(s) : p.897-905 Langues : Anglais (eng) Mots-clés : autism  cognitive control  conflict adaptation  social cognition Index. décimale : PER Périodiques Résumé : Background: The modification of performance following conflict can be measured using conflict adaptation tasks thought to measure the change in the allocation of cognitive resources in order to reduce conflict interference and improve performance. While previous studies have suggested atypical processing during nonsocial cognitive control tasks, conflict adaptation (i.e. congruency sequence effects) for social–emotional stimuli have not been previously studied in autism spectrum disorder.Methods: A total of 32 participants diagnosed with autism spectrum disorder and 27 typically developing matched controls completed an emotional Stroop conflict task that required the classification of facial affect while simultaneously ignoring an overlaid affective word.Results: Both groups showed behavioral evidence for emotional conflict adaptation based on response times and accuracy rates. However, the autism spectrum disorder group demonstrated a speed-accuracy trade-off manifested through significantly faster response times and decreased accuracy rates on trials containing conflict between the emotional face and the overlaid emotional word.Conclusion: Reduced selective attention toward socially relevant information may bias individuals with autism spectrum disorder toward more rapid processing and decision making even when conflict is present. Nonetheless, the loss of important information from the social stimuli reduces decision-making accuracy, negatively affecting the ability to adapt both cognitively and emotionally when conflict arises.

Cognitive control and conflict adaptation in youth with high-functioning autism / Michael J. LARSON in Journal of Child Psychology and Psychiatry, 53-4 (April 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-4 (April 2012) . - p.440-448 Titre : Cognitive control and conflict adaptation in youth with high-functioning autism Type de document : Texte imprimé et/ou numérique Auteurs : Michael J. LARSON, Auteur ; Mikle SOUTH, Auteur ; Peter E. CLAYSON, Auteur ; Ann CLAWSON, Auteur Année de publication : 2012 Article en page(s) : p.440-448 Langues : Anglais (eng) Mots-clés : N2  event-related potential  autism  conflict adaptation  cognitive control Index. décimale : PER Périodiques Résumé : Background:  Youth diagnosed with autism spectrum disorders (ASD) often show deficits in cognitive control processes, potentially contributing to characteristic difficulties monitoring and regulating behavior. Modification of performance following conflict can be measured by examining conflict adaptation, the adjustment of cognitive resources based on previous-trial conflict. The electrophysiological correlates of these processes can be measured using the N2, a stimulus-locked component of the event-related potential (ERP). Methods:  High-density ERPs and behavioral data [i.e. response times (RTs) and error rates] were acquired while 28 youth with ASD and 36 typically developing controls completed a modified Eriksen flanker task. Results:  Behaviorally, groups showed similar conflict adaptation effects; youth with ASD showed larger RT slowing on switch trials. For electrophysiology, controls demonstrated larger N2 amplitudes for incongruent (high-conflict) trials following congruent (low-conflict) trials than for incongruent trials following incongruent trials. Importantly, youth with ASD showed no such differences in N2 amplitude based on previous-trial conflict. Conclusions:  Lack of electrophysiological conflict adaptation effects in youth with ASD indicates irregular neural processing associated with conflict adaptation. Individuals with ASD show declines in level of conflict evaluation and adaptation. Future research is necessary to accurately characterize and understand the behavioral implications of these cognitive control deficits relative to diagnostic severity, anxiety, and personality.
