Selective attention and executive function deficits among criminal psychopaths

peer reviewedThe present study examined whether psychopaths exhibit deficits in selective attention and executive functions. Prison inmates were assigned to either a "psychopath" group or a "control" group according to their scores on the PCL-R [Hare, 1991: Toronto, Multi-Health Systems]. The two groups were compared in terms of performance on the following tests: (1) D-II cancellation, (2) Porteus Maze, (3) Modified Wisconsin Card Sorting, (4) Stroop Color Word Interference, (5) Trail Making, and (6) Tower of London. The results support the hypothesis of selective attention and specific executive function deficits among psychopaths. Specifically, psychopaths' abilities to maintain a plan and to inhibit irrelevant information were inferior to those of control participants
