Social-interactive reward elicits similar neural response in autism and typical development and predicts future social experiences.

This study looked at how autistic and non-autistic young people's brains respond to social rewards using a chat-based interaction. Surprisingly, both groups showed very similar brain responses. The main difference was that some individuals (both autistic and non-autistic) enjoyed social interactions more than others. Those who showed stronger brain responses to social rewards were more likely to enjoy meeting new people in person later on.

This 2023 study used an innovative chat-based social interaction approach to examine neural responses to social rewards in autistic youth compared to typically developing peers. Contrary to expectations, researchers found minimal group differences in both neural and behavioral responses to social-interactive rewards. Instead, variation within both groups was better explained by individual differences in self-reported social enjoyment during the task. Importantly, neural sensitivity to social-interactive rewards predicted participants' future enjoyment of face-to-face social interactions with unfamiliar peers.

These findings challenge assumptions about social reward processing differences in autism and highlight the importance of individual variation in social experiences across both autistic and neurotypical populations.

Findings suggest focusing on individual differences in social enjoyment rather than diagnostic categories when designing social interventions. Neural measures of social reward sensitivity may help predict which individuals will benefit most from peer interaction opportunities and guide personalized intervention approaches.

Challenges in initiating and responding to social-interactive exchanges are a key diagnostic feature of autism spectrum disorder, yet investigations into the underlying neural mechanisms of social interaction have been hampered by reliance on non-interactive approaches. Using an innovative social-interactive neuroscience approach, we investigated differences between youth with autism and youth with typical development in neural response to a chat-based social-interactive reward, as well as factors such as age and self-reported social enjoyment that may account for heterogeneity in that response. We found minimal group differences in neural and behavioral response to social-interactive reward, and variation within both groups was related to self-reported social enjoyment during the task. Furthermore, neural sensitivity to social-interactive reward predicted future enjoyment of a face-to-face social interaction with a novel peer.

These findings have important implications for understanding the nature of social reward and peer interactions in typical development as well as for future research informing social interactions in individuals on the autism spectrum.
