Antisocial behavior, substance use, and impulsive aggressive personality traits often co-occur, forming a coherent spectrum of psychopathology. In the current research, authors developed novel quantitative model this spectrum. Over 3 waves iterative data collection, 1,787 adult participants selected to represent range across externalizing provided extensive about specific behaviors. Statistical methods such as item response theory semiparametric factor analysis were used these data. The...
Startle-elicited blinks were measured during presentation of affective slides to test hypotheses concerning emotional responding in psychopaths.

Prior work has...
