  • Title: The contribution of spatial cues to memory: direction, but not cue, changes support response reversal learning.
    Author: Wright SL, Williams D, Evans JH, Skinner DM, Martin GM.
    Journal: J Exp Psychol Anim Behav Process; 2009 Apr; 35(2):177-85. PubMed ID: 19364227.
    Abstract:
    In four experiments, rats were trained on a response problem followed by three reversals. Rats that changed rooms between acquisition and reversals learned the reversals in fewer trials than rats that remained in the same room, even when distal visual cues were limited. Changes in orientation, even in the same room, also facilitated response reversal learning. The advantage observed with changes in orientation across reversals does not appear to be due to differences in local views or to different start positions. Direction changes, but not cue changes, may support response reversal learning by taking advantage of the natural interaction between responses and direction when one map is used.
