Abstract

Reports 2 experiments in which 80 male and 96 female Blue Spruce rats were presented a serial CS procedure consisting of 2 components: S1 followed by S2 (S1/S2). In both experiments the stimulus similarity of S1 to S2 in terms of tonal frequency was systematically manipulated. Exp I tested the effects of similarity of components in a standard shuttle-box avoidance situation. Exp II employed a conditioned emotional response paradigm measuring the suppression of consummatory licking. Results suggest that the amount of fear elicited by S1 is a direct function of the stimulus similarity of S1 to S2, and support a generalization interpretation of fear transference.
