Adolescents' heightened risk-seeking in a probabilistic gambling task

Area of Science:

• Neuroscience
• Developmental Psychology
• Behavioral Economics

Background:

• Adolescent risk-taking is a significant public health concern.
• Understanding the developmental trajectory of decision-making under risk is crucial.
• Emotional responses to outcomes may influence risky behaviors.

Purpose of the Study:

• To investigate age-related changes in decision-making under risk in males.
• To examine the development of emotional responses to gamble outcomes.
• To explore the role of counterfactually mediated emotions in adolescent risk-seeking.

Main Methods:

• A probabilistic gambling task was administered to male participants across different age groups (childhood, young adolescence, mid-adolescence, adulthood).
• Decision-making performance (maximizing expected value) and risk-seeking behavior were assessed.
• Self-reported emotional responses (relief, regret) to gamble outcomes were collected.

Main Results:

• Expected value maximization improved with age.
• Risk-seeking exhibited an inverted U-shaped developmental pattern, peaking around 14.38 years.
• The intensity of counterfactually mediated emotions (relief and regret) increased from childhood to young adolescence.

Conclusions:

• Adolescent risk-taking behavior follows a distinct developmental trajectory.
• The maturation of emotional responses to decision outcomes may contribute to adolescent risk-seeking.
• These findings offer insights into the neurobiological and psychological underpinnings of adolescent decision-making.
