Abstract In this article, we describe a new computational
model of switching between path-planning and cue-guided
navigation strategies. It is based on three main assumptions:
(i) the strategies are mediated by separate memory systems
that learn independently and in parallel; (ii) the learning algo-
rithms are different in the two memory systems--the cue-
guided strategy uses a temporal-difference (TD) learning rule
to approach a visible goal, whereas the path-planning strat-
egy relies on a place-cell-based graph-search algorithm to
learn the location of a hidden goal; (iii) a strategy selec-
