One mechanistic account of these comorbidities is that ASD is characterized by impaired emotion regulation (ER) that results in deficits modulating emotional responses. We assessed neural activation during cognitive reappraisal of faces in high functioning adults with ASD. Groups did not differ in looking time, pupilometry, or subjective ratings of faces during reappraisal. However, instructions to increase positive and negative emotional responses resulted in less increase in nucleus accumbens and amygdala activations (respectively) in the ASD group, and both regulation instructions resulted in less change in dorsolateral prefrontal cortex activation in the ASD group. Results suggest a potential mechanistic account of impaired ER in ASD.

Reward Circuitry Function in Autism During Face Anticipation and Outcomes / Gabriel S. DICHTER in Journal of Autism and Developmental Disorders, 42-2 (February 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-2 (February 2012) . - p.147-160 Titre : Reward Circuitry Function in Autism During Face Anticipation and Outcomes Type de document : Texte imprimé et/ou numérique Auteurs : Gabriel S. DICHTER, Auteur ; J. Anthony RICHEY, Auteur ; Alison M. RITTENBERG, Auteur ; Antoinette SABATINO-DICRISCIO, Auteur ; James W. BODFISH, Auteur Année de publication : 2012 Article en page(s) : p.147-160 Langues : Anglais (eng) Mots-clés : Autism  Nucleus accumbens  Anticipation  Functional magnetic resonance imaging  Social cognition  Reward Index. décimale : PER Périodiques Résumé : The aim of this study was to investigate reward circuitry responses in autism during reward anticipation and outcomes for monetary and social rewards. During monetary anticipation, participants with autism spectrum disorders (ASDs) showed hypoactivation in right nucleus accumbens and hyperactivation in right hippocampus, whereas during monetary outcomes, participants with ASDs showed hyperactivation in left midfrontal and anterior cingulate gyrus. Groups did not differ in nucleus accumbens responses to faces. The ASD group demonstrated hyperactivation in bilateral amygdala during face anticipation that predicted social symptom severity and in bilateral insular cortex during face outcomes. These results add to the growing body of evidence that autism is characterized by altered functioning of reward circuitry. Additionally, atypical amygdala activation during the processing of social rewards may contribute to the development or expression of autistic features.

The latent structure of child depression: a taxometric analysis / J. Anthony RICHEY in Journal of Child Psychology and Psychiatry, 50-9 (September 2009)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 50-9 (September 2009) . - p.1147-1155 Titre : The latent structure of child depression: a taxometric analysis Type de document : Texte imprimé et/ou numérique Auteurs : J. Anthony RICHEY, Auteur ; Christopher J. LONIGAN, Auteur ; Norman B. SCHMIDT, Auteur ; Beth M. PHILLIPS, Auteur ; Salvatore J. CATANZARO, Auteur ; Jeff LAURENT, Auteur ; Rebecca R. GERHARDSTEIN, Auteur ; Roman KOTOV, Auteur Année de publication : 2009 Article en page(s) : p.1147-1155 Langues : Anglais (eng) Mots-clés : Depression taxometrics CDI Index. décimale : PER Périodiques Résumé : Background: The current study examined the categorical versus continuous nature of child and adolescent depression among three samples of children and adolescents ranging from 5 to 19 years. Methods: Depression was measured using the Children's Depression Inventory (CDI). Indicators derived from the CDI were based on factor analytic research on the CDI and included indices of: 1) social withdrawal, 2) anhedonia, 3) incompetence/maladjustment and 4) negative self-esteem. Results: Taxometric procedures provided convergent support for the existence of a latent taxon across three independent samples. Internal and external consistency tests as well as Monte Carlo simulations supported the validity of the results. Conclusions: Multiple nonredundant procedures and samples were all consistently indicative of taxonicity in child depression.
