Abstract
ABSTRACTPsychophysiological measures—breathing amplitude (BA), breathing cycle time (BCT), eyeblink rate (EBR), eyeblink latency (EBL), finger pulse volume (FPV), heart rate (HR), palmar galvanic skin response (GSRp), volar‐forearm galvanic skin response (GSRv), and voice latency (VL)—were evaluated for effectiveness in detecting deception with 63 college students. A relevant‐irrelevant stimulus presentation format was used with three treatment conditions: personal words, neutral words, and items involving money. All physiological variables were found significant indicators of deception, p < .01 or p < .05 through objective techniques. A combined effect index of six variables provided an advantage over any index taken separately. No significant treatment or sex differences were found between stimulus conditions except for the GSRv measure.
