Differences in the Modulation of Cardiac Activity Between Psychopaths and Normal Controls

WALTER D. FENZ PHD1, MICHAEL J. YOUNG BA1, and HANS G. FENZ MA1

1 Department of Psychology, University of Waterloo

When presented with a series of signals warning of a forthcoming noxious event, psychopaths showed resistance to develop anticipatory cardiac responses to them; having developed a conditioned response pattern, they then showed resistance to extinction. This delay in responding to changes in the environment, especially to anxiety relevant cues, was attributed to a selective deficit in attention. The findings were related to studies on "real life" stress in which the development of anticipatory emotional responses had adaptive effects on performance.
