Spatial pattern learning in rats: control by an iterative pattern

Abstract

Rats searched in a matrix of vertical poles for food hidden on top of the poles. The only information available about the location of the food was the consistent spatial pattern of the baited poles, which was a checkerboard. This spatial pattern of hidden-food locations came to control the choices of poles made by the rats. The experiments ruled out the possibility that this control can be explained by the acquisition of simple response tendencies to move from pole to pole. Instead, this behavioral control of choices was attributed to the development of a representation of the checkerboard pattern of baited locations. Spatial pattern learning may have mechanisms in common with other forms of pattern learning.
