Cognitive Mechanisms Underlying Prosocial Decision Making in Callous-Unemotional Traits

Area of Science:

• Developmental Psychology
• Cognitive Neuroscience
• Child Psychiatry

Background:

• Callous-unemotional (CU) traits in youth are associated with a lack of prosocial emotions.
• Existing research on CU traits and prosocial behavior often overlooks the cognitive processes involved.
• Understanding these cognitive mechanisms is crucial for addressing core impairments in CU traits.

Purpose of the Study:

• To investigate the cognitive processes underlying prosocial decision-making in adolescents with CU traits.
• To apply drift diffusion modeling to a prosocial behavior task to examine latent cognitive processes.
• To explore potential sex differences in these cognitive processes.

Main Methods:

• Used diffusion modeling on a prosocial behavior task with 87 adolescents (ages 12-14).
• Participants decided whether to accept or reject self-serving trials (money taken from charity) or donation trials (money given to charity).
• Analyzed drift rate, threshold separation, bias, and non-decision time.

Main Results:

• CU traits were associated with increased information accumulation towards accepting self-serving trials.
• Exploratory analyses indicated males tended to reject donation trials.
• Females considered more information during self-serving trials.
• CU trait associations were independent of conduct problems.

Conclusions:

• Adolescents with CU traits exhibit a unique cognitive profile in prosocial decision-making, characterized by biased information accumulation towards self-serving choices.
• Sex differences in cognitive processes related to prosocial decisions may exist at higher CU traits.
• These findings highlight the importance of cognitive mechanisms in understanding CU traits.
