Integration of spatial relations across perceptual experiences.

People often carry out tasks that entail coordinating spatial
information encoded in temporally and/or spatially distinct perceptual
experiences. Much research has been conducted to determine whether such
spatial information is integrated into a single spatial representation or whether it
is kept in separate representations that can be related at the time of retrieval.
Here, we review the existing literature on the integration of spatial information
and present results from a new experiment aimed at examining whether
locations encoded from different perspectives in the same physical
environments are integrated into a single spatial representation. Overall, our
findings, coupled with those from other studies, suggest that separate spatial
representations are maintained in memory.
