Contagion of Temporal Discounting Value Preferences in Neurotypical and Autistic Adults

Neuroeconomics paradigms have demonstrated that learning about another's beliefs can make you more like them (i.e., contagion). Due to social deficits in autism, it is possible that autistic individuals will be immune to contagion. We fit Bayesian computational models to a temporal discounting task, where participants made decisions for themselves before and after learning the distinct preferences of two others. Two independent neurotypical samples (N = 48; N = 98) both showed a significant contagion effect; however the strength of contagion was unrelated to autistic traits. Equivalence tests showed autistic (N = 12) and matched neurotypical N = 12) samples had similar levels of contagion and accuracy when learning about others. Despite social impairments being at the core of autistic symptomatology, contagion of value preferences appears to be intact.

Automated summary

Research has shown that understanding others' beliefs can lead to contagion effects, making individuals more susceptible to influence. Despite social deficits in autism, individuals with autism showed similar levels of contagion and accuracy when learning about others compared to neurotypical individuals. The contagion of value preferences appears to be intact in individuals with autism.
