Relational learning transference in a navigation task. Three groups of rats were trained to find a hidden platform located in a fix position relative to four landmarks surrounding a swimming pool. The group No Change received active preexposure (Prados, Redhead & Pearce, 1999) lo the same landmarks (ABCD) that define the location of the platform during the training. The group Change, received active preexposure lo a set of four landmarks (LMNO) different lo lbs one used to define the platform location during training (ABCD). Finally, the Control group was preexposed to the apparatus and the trained to find the platform by reference to ASCO. The preexposed groups showed a facilitated learning when searching for the invisible platform. The performance of the group Change could be said to demostrate that learning to attend to the spatial relation between the landmarks that were present during preexposure was transferred to the new landmarks presented during the training phase. These results suggest that attentional processes play and important role in preexposure effects in the spatial domain.
