title: Differential effect of the intermixed and blocked preexposure schedules on the strength of within-compound associations.
abstract: In Experiment 1, we demonstrated an intermixed-blocked effect where intermixed preexposure to a flavor compound and to an element of that compound (AX, X, AX, X . . .) reduced generalization between them more than equivalent blocked preexposure (AX, AX . . . X, X . . . , or X, X, AX, AX). Then we used sensory preconditioning (Experiment 2) and conditioned flavor preference (Experiment 3) procedures to assess the strength of the X-A within-compound association resulting from those preexposure schedules. In both experiments, we observed that the within-compound association was stronger after blocked than intermixed preexposure. We suggest that these differences in strength produce more mediated generalization in the blocked than intermixed preexposure.
