Enhanced decision making and risk avoidance in high-functioning autism spectrum disorder.

Area of Science:

• Neuroscience
• Developmental Psychology
• Behavioral Economics

Background:

• Everyday decision-making integrates cognitive and emotional information.
• Individuals with autism spectrum disorder (ASD) often experience difficulties in decision-making.
• Underlying decision-making mechanisms in young people with ASD remain underexplored.

Purpose of the Study:

• To investigate decision-making processes in children and adolescents with ASD.
• To compare the performance and psycho-physiological responses of individuals with ASD and typical controls on an affective decision-making task.

Main Methods:

• Study included 48 children and young adolescents with ASD and 54 age- and ability-matched typical controls (CON).
• Participants completed the Iowa Gambling Task (IGT), an affective decision-making task.
• Performance and psycho-physiological arousal were evaluated during the task.

Main Results:

• ASD participants exhibited superior overall performance on the IGT compared to controls (p < .05).
• ASD participants showed significantly better learning in later stages of the task.
• While both groups had similar arousal to disadvantageous choices, ASD participants favored advantageous decks, whereas controls chose more from frequent-gain disadvantageous decks.

Conclusions:

• A decision-making style focused on loss avoidance may benefit ASD individuals in certain contexts.
• This loss-avoidant strategy might hinder functioning in complex social situations where reward seeking is more adaptive.
• Understanding these distinct decision-making styles is crucial for supporting individuals with ASD in various life domains.
