Exposure to Spatial Cues Facilitates Visual Discrimination but Not Spatial Guidance

The performance in a radial-arm maze of two groups of rats with restricted access to extra-maze visual cues was studied. One group received extensive exposure to the visual environment of the maze, whereas the second group was never exposed to the environment, aside from their experience in the maze itself. Spatial exposure resulted in a slightly improved ability to discriminate between previously visited and unvisited spatial locations, which can be explained on the basis of general perceptual learning processes. However, there was no evidence that spatial exposure resulted in control of choices by the spatial relations among the maze locations. These results are discussed in terms of theories of spatial learning which appeal to perceptual learning and cognitive mapping.
