  • Title: Competition between landmarks in spatial learning: the role of proximity to the goal.
    Author: Chamizo VD, Manteiga RD, Rodrigo T, Mackintosh NJ.
    Journal: Behav Processes; 2006 Jan 10; 71(1):59-65. PubMed ID: 16338101.
    Abstract:
    In two experiments, rats were trained to find a hidden platform in a Morris pool in the presence of two landmarks. Landmark B was present on all training trials, on half the trials accompanied by landmark A, on the remainder by landmark C. For rats in Group Bn, B was near the location of the platform; for those in Group Bf, B was far from the platform. Group Bn performed better than Group Bf on test trials to B alone, but significantly worse on test trials to a new configuration formed by A and C. Thus, the spatial proximity of B to the platform affected not only how well it could be used to locate the platform, but also its ability to prevent learning about other landmarks.
