1 some primitive mechanisms of spatial attention
| Abstract | Among the studies we have carried out to support these ideas are ones showing the subjects can track multiple independent moving targets in a field of identical distractors, that their ability to track these targets and detect changes occurring on them does not generalize to nontargets nor to items lying inside the convex polygon that they form (so that a zoom-lens of attention does not fit the data). We have used a visual search paradigm to show that (serial or parallel) search can be confined to a subset of indexed items and the layout of these items is of little importance. We have also carried out a large number of studies on the phenomenon known as subitizing and have shown that subitizing occurs only when items can be preattentively individuated and in those.. | |||||||||
