THE EFFECTS OF VERBAL RESPONSES ON THE LABORATORY DETECTION OF DECEPTION

Abstract

ABSTRACT S s were given one of three different response tasks to perform in a detection of deception experiment using the galvanic skin response (GSR). The first group was told to say nothing as they heard each question, the second group to say “no” to each question, and the third group to make a word association to each question. Questions were presented in both a random order and a known sequential order. There were over‐all differences among the three groups for both conditions of question presentation. The second group was most frequently detected, the first group next, and the third group was detected least frequently. Differences between experimental procedures used in this study and other studies using word association do not permit comparison of the results of this study with other studies.
