Perceptions vs. Reality: A Longitudinal Experiment in Influenced Judgment Performance

Government reliance on computer-mediated information has transformed it from "enabler" to "target" which now demands the detection of manipulated and deceptive measures a primary security objective. As people are not inherently good performers at detecting deceptive communications, this study draws on interpersonal deception theory (Burgoon, 1986) and social cognitive theory (Bandura, 1986) to measure personal perceptions that influence decisions operationalized as the successful detection of a deceptive measure. Department of Defense personnel (N=119) participated in a longitudinal experiment that measured detection performance before and after training and feedback treatments. Self-efficacy and perceived training effectiveness emerged as dominant factors in predicting performance.
