Deliberate and Affective Driven Decision-Making. A 10-Year Longitudinal Study of Decision-Making in Autism

We investigated the developmental trajectory of decision-making in autistic individuals from childhood into emerging adulthood and examined the impact of internalizing symptoms on decision-making strategies. Thirty-eight autistic and 50 non-autistic individuals were assessed at baseline (Mage = 11.8 years, 72.7% boys), at 2-year, and 10-year follow-up. Autistic and non-autistic individuals showed similar improvements in decision-making performance over time. However, the autistic participants exhibited a more risk-averse decision-making style compared to the non-autistic participants. The pattern of risk-averse decision-making in the autistic individuals reflected a more deliberate thinking style in advantageous situations and the influence of internalizing symptoms in disadvantageous situations.
