Yes. The saliency of the relevant issue should not be affected by this or other personality disorders. A psychopath that lies will "know" he is lying regardless of their emotional guilt/remorse. Side issue for this topic: It would be interesting to know whether a DLC format would be more effective than PLCs with psychopaths......

Psychopathy is NOT included in the DSM-IV-TR or any other version of DSM.

It is important to remember that psychopathy is not synonymous with APD, and that APD was not intended to be synonymous with criminality.

Barland, Gordon and Raskin, David (1974) Psychopathy and detection of deception in criminal suspects:

No significant differences in total scores of the two groups (-7.9 for psychopaths, -9.0 for non psychopaths) No difference between detectability of the two.

77 criminal suspects administered field polygraph tests for defense and prosecuting attorneys using ZCT. The Pd scale and K scale of the MMPI were administered to each. of 56 DI exainees, 15 highest and lowest put in separate groups. Highest 15 were 2% of general population. The other 15 were in the bottom 76% of Population.

This was also done in a lab study by Balloun, Kristen & Holmes, David in 1979 with no significant differences between examinees with highest and lowest Pd scale scores.

David Hammond L. (1980) obtained same results with 100% of guilty psychopaths accurately detected.

Patrick & Iacono found no difference in 1989

Raskin & Hare 1978...no significant differences.

Answer appears to be yes they can with normal success equal to that of the general population.

Yes, and isn't "Hare" the Hare who developed the Psychopathy Checklist (which is generally used to diagnose psychopathy)?
