Visual monitoring performance in three subgroups of male delinquents
Administered a questionnaire measuring psychopathic, neurotic, and subcultural delinquency to 268 male delinquents. 3 groups of 15 Ss each were formed from Ss who scored above the mean on 1 scale and below the mean on the other 2. It was predicted that the more psychopathic Ss would show a greater performance decrement on a vigilance task. A significant effect was found between groups and a significant decrement over trials for signals detected and RTs; psychopathic Ss performed consistently poorer than the other 2 groups.
