Note. Assessments: Correlations among assessment variables. PCL-R Total is the Total score derived from the Psychopathy Checklist – Revised (Hare, 2003); PCL-R Factor 1 and Factor 2 are Factor 1 and Factor 2 scores derived from the PCL-R; PCL-R Facet 1, Facet 2, Facet 3, and Facet 4 scores are Facet 1, 2, 3, and 4 scores derived from the PCL-R (Hare, 2003); Intelligence Quotient (IQ) was calculated from the Wechsler Adult Intelligence Scale – Third Version (WAIS-III; Wechsler, 1997); Sub. Dep. is the number of substance dependencies calculated from the Structured Clinical Interview for DSM-IV Axis I Disorders-Patient Version (SCID I/P; First, et al., 1995). NoGo Accuracy is the participant’s accuracy to NoGo stimuli. Go Accuracy is the participant’s accuracy to Go stimuli.
