Abstract

In two experiments, rats first received preexposure to a rectangular arena in which the geometrically equivalent corner pairs (G1 and G2) were coincident with different luminance characteristics (C1 and C2, respectively). In Experiment 1, rats were then placed in a uniform gray rectangular arena where food was located in one geometrically equivalent pair of corners (G1), but not another (G2). Finally, rats were tested in a square arena with C1 and C2 and preferred to search in C1 rather than C2. In Experiment 2, following preexposure to G1C1 and G2C2, rats received pairings of C1 with food and C2 with no food in a square arena. During testing, rats preferred to search in G1 rather than G2 in a gray rectangular arena. These results demonstrate that reciprocal within-compound associations develop between geometric and luminance information and thereby challenge the view that there is a dedicated geometric module that is impenetrable to information that is not geometric.
