  • Title: The effects of overtraining in the Morris water maze on allocentric and egocentric learning strategies in rats.
    Author: Kealy J, Diviney M, Kehoe E, McGonagle V, O'Shea A, Harvey D, Commins S.
    Journal: Behav Brain Res; 2008 Oct 10; 192(2):259-63. PubMed ID: 18514924.
    Abstract:
    Animals can use both allocentric and egocentric strategies to learn a spatial task. Our results suggest that allocentric cues are more dominant than idiothetic cues in guiding navigation. Animals do not necessarily learn an egocentric strategy automatically, instead they probably hold just one solution to any particular task at a time until forced to learn an alternative strategy. Further, with overtraining animals do not always switch from allocentric to an egocentric learning strategy perhaps challenging suggestions of a stored hierarchy of strategies.
