Parieto-occipital areas involved in efficient filtering in search: A time course analysis of visual marking using behavioural and functional imaging procedures.

Two studies were conducted to investigate the time course of the preview benefit—the presenting of one set of distractions before the presenting of a second set of distractors and a target. Findings revealed that the preview benefit has a relatively slow time course, and that old items are discount...

Sumario:Two studies were conducted to investigate the time course of the preview benefit—the presenting of one set of distractions before the presenting of a second set of distractors and a target. Findings revealed that the preview benefit has a relatively slow time course, and that old items are discounted from searches in parallel. Moreover, parts of the parieto-occipital cortex are selectively activated during a preview search condition relative to a detection baseline.
