ABSTRACTWe investigated the participation of associative processes in the extinction of spatial memory in humans. Three groups were trained to locate a hidden platform whose location was indicated by a set of distal cues. During a test trial without platform, the groups showed a preference for the reinforced quadrant which gradually decreased with no differences between them. The loss of the preference for the reinforced quadrant was suitably fitted to an exponential function. This is consistent with an extinction effect, which occurred as predicted by several models of associative learning. The theoretical and applied implications of this result are discussed.
