  • Title: Emotion in the criminal psychopath: fear image processing.
    Author: Patrick CJ, Cuthbert BN, Lang PJ.
    Journal: J Abnorm Psychol; 1994 Aug; 103(3):523-34. PubMed ID: 7930052.
    Abstract:
    We tested the hypothesis that the response mobilization that normally accompanies imagery of emotional situations is deficient in psychopaths. Cardiac, electrodermal, and facial muscle responses of 54 prisoners, assigned to low- and high-psychopathy groups using R. D. Hare's (1991) Psychopathy Checklist--Revised, were recorded while subjects imagined fearful and neutral scenes in a cued sentence-processing task. Groups did not differ on self-ratings of fearfulness, imagery ability, or imagery experience. Low-psychopathy subjects showed larger physiological reactions during fearful imagery than high-psychopathy subjects. Extreme scores on the antisocial behavior factor of psychopathy predicted imagery response deficits. Results are consistent with the idea that semantic and emotional processes are dissociated in psychopaths.
