Autistic traits are related to worse performance in a volatile reward learning task despite adaptive learning rates / Judith GORIS in Autism, 25-2 (February 2021)
[article]
Titre : Autistic traits are related to worse performance in a volatile reward learning task despite adaptive learning rates Type de document : Texte imprimé et/ou numérique Auteurs : Judith GORIS, Auteur ; Massimo SILVETTI, Auteur ; Tom VERGUTS, Auteur ; Jan R. WIERSEMA, Auteur ; Marcel BRASS, Auteur ; Senne BRAEM, Auteur Article en page(s) : p.440-451 Langues : Anglais (eng) Mots-clés : autism spectrum disorders learning rate reward decision-making Index. décimale : PER Périodiques Résumé : Recent theories propose that autism is characterized by an impairment in determining when to learn and when not. Here, we investigated this hypothesis by estimating learning rates (i.e. the speed with which one learns) in three different environments that differed in rule stability and uncertainty. We found that neurotypical participants with more autistic traits performed worse in a volatile environment (with unstable rules), as they chose less often for the most rewarding option. Exploratory analyses indicated that performance was specifically worse when reward rules were opposite to those initially learned for participants with more autistic traits. However, there were no differences in the adjustment of learning rates between participants with more versus less autistic traits. Together, these results suggest that performance in volatile environments is lower in participants with more autistic traits, but that this performance difference cannot be unambiguously explained by an impairment in adjusting learning rates.
