Visual search has no memory

Article Abstract:

New research raises doubts about the assumption in theories of visual search that search relies on accumulating information about the identity of objects over time. This research presents the possibility that visual search processes are amnesic, acting on neural representations that are constantly rewritten and do not exist permanently outside the time span of visual persistence. It has been shown that the visual system does not accumulate information about object identity over time during searching. There is minimal integration of visual information across saccadic eye movements.
