Awareness of crime-relevant information and the Guilty Knowledge Test.
Abstract
The effects of awareness of crime-relevant information on the detection of deception with the Guilty Knowledge Test were examined. Student subjects were assigned to 1 of 3 groups: a guilty group, members of which commited a mock crime; an innocent group aware of details about the crime; or an innocent group unaware of such information. After following instructions, subjects were tested on the polygraph with a 10-item Guilty Knowledge Test and were offered $20.00 for an innocent test outcome. Skin resistance responses scores of guilty subjects lying about crime-relevant information were higher than the scores of innocent informed subjects, whose scores in turn were higher than those of innocent unaware subjects.
