Atypical Brain Responses to Reward Cues in Autism as Revealed by Event-Related Potentials / Gregor KOHLS in Journal of Autism and Developmental Disorders, 41-11 (November 2011)
[article]
Titre : Atypical Brain Responses to Reward Cues in Autism as Revealed by Event-Related Potentials Type de document : Texte imprimé et/ou numérique Auteurs : Gregor KOHLS, Auteur ; Judith PELTZER, Auteur ; Martin SCHULTE-RUTHER, Auteur ; Inge KAMP-BECKER, Auteur ; Helmut REMSCHMIDT, Auteur ; Beate HERPERTZ-DAHLMANN, Auteur ; Kerstin KONRAD, Auteur Année de publication : 2011 Article en page(s) : p.1523-1533 Langues : Anglais (eng) Mots-clés : Social reward Monetary reward Motivation Autism spectrum disorders Event-related brain potentials P3 Go/no-go task Index. décimale : PER Périodiques Résumé : Social motivation deficit theories suggest that children with autism do not properly anticipate and appreciate the pleasure of social stimuli. In this study, we investigated event-related brain potentials evoked by cues that triggered social versus monetary reward anticipation in children with autism. Children with autism showed attenuated P3 activity in response to cues associated with a timely reaction to obtain a reward, irrespective of reward type. We attribute this atypical P3 activity in response to reward cues as reflective of diminished motivated attention to reward signals, a possible contributor to reduced social motivation in autism. Thus, our findings suggest a general reward processing deficit rather than a specific social reward dysfunction in autism.

Titre : Common alterations in sensitivity to type but not amount of reward in ADHD and autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Ellen DEMURIE, Auteur ; Herbert ROEYERS, Auteur ; Dieter BAEYENS, Auteur ; Edmund J. S. SONUGA-BARKE, Auteur Année de publication : 2011 Article en page(s) : p.1164-1173 Langues : Anglais (eng) Mots-clés : ADHD ASD reward sensitivity monetary reward social reward Index. décimale : PER Périodiques Résumé : Background: Children with attention deficit/hyperactivity disorder (ADHD) display abnormalities in reward processing. Most reward studies have focused on the effects of material or monetary rewards. Studies with autism spectrum disorder (ASD) have focused on social rewards. In this study we compared the effects of amount and type of reward in children with ADHD and those with ASD.
Methods: Two adapted versions of the Monetary Incentive Delay Task were used to study the effects of monetary and social reward anticipation on performance in 40 typically developing (TD) children and adolescents (8–16y), 35 children and adolescents with ADHD and 31 children and adolescents with ASD.
Results: Monetary and social reward improved accuracy and response time (RT) in all groups. The higher the anticipated reward, the more accurate and faster were responses. Independent of these effects, there was a differential effect of reward type. Both clinical groups, but not TD, responded faster for monetary than social rewards.
Conclusions: The results, while not supporting hyposensitivity to changes in reward amount in ADHD and ASD, do suggest that both groups are generally less motivated in settings where social as opposed to monetary rewards can be earned.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02374.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=145
