Rare items often missed in visual searches
Article Abstract:
Performance on high-and low-prevalence version of an artificial baggage-screening task in which observers looked for tools among objects drawn from other categories is compared. Semi-transparent objects are presented against noisy backgrounds that are sometimes overlapping.

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.
