Neural Mechanisms of Vicarious Reward Processing in Adults with Autism Spectrum Disorder / Rachel K. GREENE in Autism Research and Treatment, 2020 (2020)  

Public ISBD [article]  inAutism Research and Treatment > 2020 (2020) Titre : Neural Mechanisms of Vicarious Reward Processing in Adults with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Rachel K. GREENE, Auteur ; Cara R. DAMIANO-GOODWIN, Auteur ; Erin WALSH, Auteur ; Joshua BIZZELL, Auteur ; Gabriel S. DICHTER, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Previous studies examining the neural substrates of reward processing in ASD have explored responses to rewards for oneself but not rewards earned for others (i.e., vicarious reward). This omission is notable given that vicarious reward processing is a critical component of creating and maintaining social relationships. The current study examined the neural mechanisms of vicarious reward processing in 15 adults with ASD and 15 age- and gender-matched typically developing controls. Individuals with ASD demonstrated attenuated activation of reward-related regions during vicarious reward processing. Altered connectivity was also observed in individuals with ASD during reward receipt. These findings of altered neural sensitivity to vicarious reward processing may represent a mechanism that hinders the development of social abilities in ASD.

Vicarious Effort-Based Decision-Making in Autism Spectrum Disorders / Maya G. MOSNER in Journal of Autism and Developmental Disorders, 47-10 (October 2017)

Participants made choices to win money for themselves or for another person. When choosing for themselves, the ASD group exhibited relatively similar patterns of effort-based decision-making across reward parameters. However, when choosing for another person, the ASD group demonstrated relatively decreased sensitivity to reward magnitude, particularly in the high magnitude condition. Finally, patterns of responding in the ASD group were related to individual differences in consummatory pleasure capacity. These findings indicate atypical vicarious effort-based decision-making in ASD and more broadly add to the growing body of literature addressing social reward processing deficits in ASD.
