Common alterations in sensitivity to type but not amount of reward in ADHD and autism spectrum disorders / Ellen DEMURIE in Journal of Child Psychology and Psychiatry, 52-11 (November 2011)
[article]
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

[article]
Titre : Disrupted Stimulus Control But Not Reward Sensitivity in Individuals with Autism Spectrum Disorders: A Matching Law Analysis Type de document : Texte imprimé et/ou numérique Auteurs : Phil REED, Auteur ; Rose HAWTHORN, Auteur ; Sam BOLGER, Auteur ; Katie MEREDITH, Auteur ; Ruth BISHOP, Auteur Article en page(s) : p.2393-2403 Langues : Anglais (eng) Mots-clés : Stimulus control Reward sensitivity Matching Index. décimale : PER Périodiques Résumé : The matching law suggests that behavior is emitted in proportion to the level of reinforcement available. The current study investigated this effect in individuals with autism spectrum disorders (ASD), and focused on the effects of magnitude of reinforcement (Study 1), and rate of reinforcement (Studies 2 and 3), on matching performance. Studies 1 and 2 employed lower functioning children with ASD, and demonstrated matching in both groups, but that the group with ASD displayed greater levels of stimulus bias. Study 3 employed higher functioning children with ASD, and found little evidence of matching, but higher stimulus bias in the group with ASD. These effects suggest a disruption of stimulus control, but not reward sensitivity, in individuals with ASD.

MASON, Auteur Article en page(s) : p.1056-1066 Langues : Anglais (eng) Mots-clés : Binge eating impulsivity reward sensitivity eating disorder personality risk factors Index. décimale : PER Périodiques Résumé : Background The present study examined facets of impulsivity and reward sensitivity [as measured by the UPPS-P Impulsive Behavior Scale and Behavioral Activation and Behavioral Inhibition Scales (BIS/BAS)] as multivariable predictors of subsequent binge-eating disorder (BED) course of illness in middle childhood. Methods The current sample included children aged 910years (N = 9,438) who took part in the baseline and 1-year follow-up assessments of the Adolescent Brain Cognitive Development (ABCD) study. BED course was operationalized as those who never developed BED or subthreshold BED (SBED) (control), were diagnosed with BED/SBED at year 1 but not baseline (developers), were diagnosed with BED/SBED at baseline but not year 1 (remitters), or were diagnosed with BED/SBED at both times (maintainers). Results Higher baseline BIS/BAS reward responsivity scores were related to the greater likelihood of belonging to the maintainer group relative to the control and remitter groups (ORs1.121.19). Regarding covariates, higher baseline body mass index percentile and internalizing symptoms were related to the greater likelihood of BED development, remittance, and maintenance compared to the control group (ORs = 1.041.14); no variables were uniquely related to BED development. Exploratory analyses showed that the likelihood of belonging to the maintainer group compared to the control group was greatest at higher levels of negative urgency in combination with high reward responsivity. Conclusions Heightened reward responsivity may convey risk for poorer BED course in children, while emotional disorder symptomatology may act as a more general risk and maintenance factor for BED.

Nineteen high function children with higher functioning Autism Spectrum Disorder (HFASD) and 23 age, gender, and IQ matched children with typical development (TD) used a joy stick to position themselves closer or further from virtual avatars while attempting to identify six emotions expressed by the avatars, happiness, fear, anger, disgust, sadness, and surprise that were expressed at different levels of intensity. The results indicated that children with HFASD displayed significantly less approach behavior to the positive happy expression than did children with TD, who displayed increases in approach behavior to higher intensities of happy expressions. Alternatively, all groups tended to withdraw from negative emotions to the same extent and there were no diagnostic group differences in accuracy of recognition of any of the six emotions. This pattern of results is consistent with theory that suggests that some children with HFASD display atypical social-approach motivation, or sensitivity to the positive reward value of positive social–emotional events. Conversely, there was little evidence that a tendency to withdraw from social–emotional stimuli, or a failure to process social emotional stimuli, was a component of social behavior task performance in this sample of children with HFASD.
