Visual selection mediated by location: selecting successive visual objects.
In these experiments, each stimulus consists of a series of frames, each containing a target digit of one color and a distractor digit of another color. The task is to name the highest digit of the target color. Subjects make fewer errors when successive targets appear at the same location than when they appear at different locations, apparently because they select target objects by using a mec...
متن کاملSelecting and perceiving multiple visual objects.
To explain how multiple visual objects are attended and perceived, we propose that our visual system first selects a fixed number of about four objects from a crowded scene based on their spatial information (object individuation) and then encode their details (object identification). We describe the involvement of the inferior intra-parietal sulcus (IPS) in object individuation and the superio...
متن کاملSelection of new objects by onset capture and visual marking
Visual search is easier after looking at some distractors in advance because previewed distractors are excluded from the search (preview benefit). A dominant explanation for preview benefit is that it occurs because of the inhibition of old objects (visual marking). However, another view claims that preview benefit simply reflects automatic attentional orienting to new objects (onset capture). ...
متن کاملStoring objects in visual short-term memory: Location is key
There are two views that describe the capacity of visual short-term memory (VSTM): one that posits that capacity has a strict upper limit, and the other that states that capacity has no fixed upper limit. Here we attempt to reconcile these views by measuring capacity of VSTM in two experiments where the number of objects (cubes) and the number of features (colors) in an object were varied indep...
متن کاملEmergence of visual objects involves multiple stages of spatial selection.
Attention may select objects or perceptual groups as fundamental units. Previous studies with event-related potentials (ERPs) have found that obligatory attention-spreading over spatial regions within stable objects is associated with intermediate feedforward visual processing, as reflected by the posterior N1 component of the ERP at a latency of 140-180 ms. The present study examined object-ba...
