Collection: Neural Tracking of Rewards and Punishments in Delinquent and Non-Delinquent Youth

Description: General linear model for knock decisions on the Social Analogue Risk Task across the full sample (both delinquent and non-delinquent youth). Analyses only included knock decisions made for doors ending in cash-outs because slams artificially curtail participants' knocking behavior. For knock decisions, a parametric modulator (PM) modeled increasing punishment (angry faces) across decisions. Thus, the PM represents the number of knocks for each decision, which were centered within-person for each trial around the average knock for each face. This PM allows us to examine how the brain tracks increasing punishment (i.e., faces morphing into an angry expression). To compare this effect between our two groups of delinquent and non-delinquent youth, we conducted a two-sample t-test on this contrast of interest. This image does not correspond to any tables or figures in the manuscript because there were no significant differences between groups.
