Abstract

Objective: Learning to successfully navigate the social world, in particular when to trust others and how to work together with them, is crucial to well-adjusted social development. This is especially the case during adolescence, when individuals are undergoing significant biological and social changes. Adolescents with conduct problems (CP) tend to have difficulties in social relationships and to display aggressive behaviors as well as reduced cooperation with others. This pattern appears to be particularly pronounced in adolescents with CP and high callous-unemotional traits (CP/HCU). However, very little is currently known about the mechanisms that might drive reduced cooperative behaviors in adolescent CP, and whether these differ for individuals with high vs low levels of CU traits.

Method: We used a series of economic games to assess how adolescents with CP/HCU (n = 46), CP, and lower levels of CU traits (CP/LCU) (n = 46), and typically developing adolescents (TD) (n = 59) interacted with social (human) and non-social (computer) partners that varied in their degree of cooperation (trustworthy vs untrustworthy and friendly vs unfriendly), and whether this related to group differences in social preferences (aversion to inequality) and prior beliefs.

Results: Adolescents with CP (both HCU and LCU) had more difficulty than TD adolescents in differentiating between trustworthy and untrustworthy social environments in our task. Adolescents with CP/LCU also had more difficulty coordinating with friendly and unfriendly social partners to produce rewarding outcomes than TD adolescents. Surprisingly, we saw no relationship between participants' inequality aversion or prior beliefs and social learning in our games.

Conclusion: These findings indicate that, under controlled experimental conditions, adolescents with CP have more difficulty learning to differentiate between social environments that vary in cooperation, particularly adolescents with CP/LCU. These findings were not explained by inequality aversion or prior beliefs. Our findings also raise important questions regarding methods used to understand the mechanisms underlying social behaviors in adolescents with CP.

Plain language summary

In this interesting study of 151 boys between the ages of 11 and 16 years, authors used economic games to investigate how adolescents with conduct problems learn to cooperate with social (human) and nonsocial (computer) partners under various social environments. The authors found that, relative to peers without any conduct problems, adolescents with conduct problems had difficulty gauging trustworthiness in social environments and coordinating with social partners to achieve rewarding outcomes. These findings were not explained by social preferences or prior beliefs. Adolescents with conduct problems and conduct problems with low callous unemotional traits may have more difficulty determining who is trustworthy and friendly, respectively, which may lead to reliance on aggression to cope with these difficulties.
