title: The geometric module in the rat: independence of shape and feature learning in a food finding task.
abstract: Rats found food in a rectangular enclosure in three experiments testing how learning about a distinctive feature near a goal interacts with learning based on the geometry of an enclosure. Rats trained to follow a feature in square and triangular enclosures and to use geometry in the rectangle followed the feature when it was in the rectangle (Experiment 1). Rats trained with the feature in a geometrically consistent corner of the rectangle learned about both geometry and the feature (Experiment 2). Training with the feature in the square did not block learning of geometry when both predicted the location of food in the rectangle (Experiment 3). The "geometric module" (Cheng, 1986) may have a special status in spatial learning.
