Risky decision-making in children with and without ADHD: A prospective study

Area of Science:

• Neurodevelopmental disorders
• Cognitive psychology
• Behavioral neuroscience

Background:

• Learning from experience is crucial for effective decision-making.
• Difficulties in experiential learning may be linked to risky decision-making.
• Attention-deficit/hyperactivity disorder (ADHD) may involve altered decision-making processes.

Purpose of the Study:

• To investigate the relationship between ADHD and risky decision-making.
• To examine learning from experience in children with and without ADHD using a sequential decision-making task.

Main Methods:

• Longitudinal study of 192 children (5-10 years) with and without ADHD over 2.5 years.
• Utilized the Balloon Emotional Learning Task (BELT), a computerized assessment of sequential risky decision-making.
• BELT included three conditions with varying explosion points (variable, stable-early, stable-late) to assess learning.

Main Results:

• ADHD status was not associated with increased risk-taking overall.
• Younger children with ADHD exhibited reduced risk-taking compared to controls.
• Typically developing children showed learning gains in both stable conditions.
• Children with ADHD learned in the stable-early condition but not the stable-late condition.

Conclusions:

• Contrary to expectations, ADHD was not linked to greater risk-taking.
• Children with ADHD demonstrated specific difficulties in learning from experience, particularly in tasks requiring more extensive learning.
• These learning deficits may partially explain negative outcomes associated with childhood ADHD, as adapting to environmental demands relies on feedback-guided behavior.
