Abstract

Animals form spatial representations of environments called cognitive maps, which allow for spatial knowledge to be used in a flexible manner (O’Keefe & Nadel, 1978). For example, using a cognitive map permits navigation from a novel start location to a known goal location. However, Sutherland, Chew, Baker, and Linggard (1987) showed that in the Morris water maze rats had difficulty finding a known goal location from a novel start location. They concluded that the spatial information contained in the map might not be used in a flexible manner (Sutherland et al., 1987). The present study reveals that the impairment reported by Sutherland et al. is due to a stimulus generalization decrement.
