Abnormalities in neural feedback-processing systems may play a role in the development of dysfunctional behavior in individuals diagnosed with conduct disorder (CD). The present study investigated the relation between CD adolescents and feedback processing by measuring event-related potentials (ERPs) in a single outcome gambling task, which included reward valence (loss and gain) and reward magnitude (10 and 50 cents) as outcomes. N2 and P3 components have been established as effective indicators in studies of behavioral disinhibition, reward processing, and decision-making. Eighteen adolescent males (age: 13–17 years) diagnosed with CD and 19 healthy age-matched male controls were recruited. Compared to healthy controls, CD individuals exhibited reduced N2 amplitudes in response to loss condition. There was also a significant decreased P3 amplitude in all conditions. The amplitudes of P3 were negatively correlated with impulsivity scores across both groups, and the amplitudes of N2 were positively correlated with impulsivity scores across both groups. Our findings suggest that adolescents with CD may be impaired in neural sensitivity feedback and the processing of environmental cues compared to healthy controls. Moreover, N2 and P3 may be reliable indices to detect different sensitivity in reward and punishment feedback processing.
