Efficacy of Repeated Psychophysiological Detection of Deception Testing

Abstract

This study was designed to determine how reliable and valid a Zone Comparison PDD test is when the same individuals are administered the same test on two different occasions. Seventy-two subjects were used in an analog mock crime study using a Zone Comparison test format. Thirty-six subjects were randomly assigned to "innocent" and thirty-six to "guilty" programmed conditions. In addition, each subject was assigned to either an "accurate", "inaccurate", or "no" feedback treatment group. The overall accuracy for Tests 1 and 2 was 67% and 61 % respectively. Excluding the inconclusive decisions, the accuracy for Test 1 was 94% and 88% for Test 2. Both Test results discriminated between guilty and innocent subjects. There were no significant differences: between the guilty subjects on Test 1 and Test 2; between the innocent subjects on Test I and Test 2; nor between the guilty and innocent subjects on Test 1. However, the accuracy for the guilty subjects on Test 2 was significantly different from the accuracy rate for innocent subjects on Test 2. There was no significant difference for the innocent subjects between Test 1 and Test 2, and no significant differences between feedback groups.

Comparison of Utah and DoDPI Scoring Accuracy: Equating Veracity Decision Rule, Chart Rule, and Number of Data Channels Used

“…The three chart rule may have been adopted because it was believed that data produced after three question series was less diagnostic or useful due to habituation (Balloun & Holmes, 1979;Suzuki & Hikita, 1964). However, recent work has shown that the strength and diagnosticity of the data signals do not degrade with additional presentations (Dollins, Cestaro, & Pettit, 1998;Elaad & Ben-Shakhar, 1997;Nakayama & Kizaki, 1990;Yankee & Grimsley, 1987) . The Utah approach uses either three or five charts.…”

The containment approach: An aggressive strategy for the community management of adult sex offenders.

“…Maintenance polygraphs should be used frequently when the supervision team has reason to believe the offender may be at risk of reoffending. The Department of Defense Polygraph Institute (Dollins, Cestaro, & Pettit, 1995) reported the efficacy of repeated polygraph testing for the Zone Comparison Test, so concerns about the habituation of offenders to frequent polygraphs may be unfounded.…”

Does incongruence of lexicosemantic and prosodic information cause discernible cognitive conflict?

“…For this reason alone, dependence on behavioral performance measures may not provide a clear or reliable answer to the question of whether or not lexicosemantic/prosodic incongruence causes cognitive conflict. Furthermore, whereas we may mask or alter our true behavioral reactions via conscious choice, it is much more difficult to consciously choose to alter our psychophysiological reactions (Dollins, Cestaro, & Pettit, 1998). These may therefore represent a more objective index of the response to cognitive conflict.…”
