Cognitive maps not used by humans (Homo sapiens) during a dynamic navigational task

To account for the impressive navigational ability of animals, some researchers have suggested that animals might use a cognitive map. Two groups of human participants (Homo sapiens) were tested for cognitive mapping using procedures similar to those used by B. M. Gibson and A. C. Kamil (2001). Participants who had to acquire spatial information about a hidden goal from the experimental contingencies alone showed patterns of search most like nutcrackers in the companion study (B. M. Gibson & A. C. Kamil, 2001). Surprisingly, postexperimental questionnaires revealed that most participants used an alternative strategy of vector integration rather than cognitive mapping during search for the hidden goal. The current study and its companion indicate that some simpler mechanisms of navigation are flexible enough to account for what appears to be map-based behavior in human and nonhuman species.
