Response perseveration in psychopathic women

Recent attempts to validate the Psychopathy Checklist-Revised (PCL-R) as a measure of psychopathy in female offenders have been limited by a failure to examine laboratory correlates of the syndrome. We assessed 112 incarcerated women by using the PCL-R and examined their performance on a card perseveration task that has been used to demonstrate response perseveration in psychopathic men. Contrary to prediction, psychopathic women did not perseverate responding when the PCL-R was used either dimensionally or categorically. The authors discuss the implications of the results for the PCL-R and for female psychopathy more generally.
