| Abstract: | Investigated the effects of providing Ss with feedback concerning their physiological responding while they were questioned about (a) innocent associations varying in degree of personal involvement and (b) innocent associations vs guilty knowledge. In Exp I, 48 undergraduates were divided into 3 groups—electrodermal, heart-rate, or no feedback. Ss were then questioned separately about a list of geometric figures, containing one that they had chosen beforehand, and about a list of Social Security numbers, which included their own. Results, based on the relative amplitude of electrodermal responses, indicate that feedback significantly augmented responses to the relevant item as did personal involvement. In Exp II, 26 undergraduates were provided with guilty knowledge about a mock crime while another 26 Ss received innocent associations. Half of each group received electrodermal feedback and half no feedback. Results show significant differences in the responding of guilty and innocent Ss. Feedback increased responding to relevant items in both groups. (5 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
