| Abstract: | Rats were required in three experiments to find one of two submerged platforms that were situated in the same pair of diagonally
opposite corners of a rectangular grey swimming pool. The experimental groups were trained with landmarks, comprising A4 cards
attached to the walls, located in the corners containing the platforms. For the control groups, the landmarks were situated
in the corners containing the platforms for half of the trials, and in the other corners for the remaining trials. Learning
about the positions of the platforms with reference to the shape of the pool was overshadowed in the experimental groups when
the landmarks were white, and enhanced when the landmarks were black. A fourth experiment assessed whether geometric cues
influenced the control acquired by the landmarks. As in the previous experiments, the presence of the geometric cues overshadowed
learning about the landmarks when they were white, but enhanced learning when the landmarks were black. |
