Reward does not modulate the preview benefit in visual search

چکیده
Preview benefit refers to faster search for a target when subset of distractors is seen prior the display. We investigated whether reward modulates this effect. Participants identified ...

A psychophysical investigation into the preview benefit in visual search
In preview search, half of the distracters are presented ahead of the remaining distracters and the target. Search under these conditions is more efficient than when all the items appear together (Watson & Humphreys, 1997). We investigated the mechanisms contributing to this preview benefit using an orientation discrimination task. In a display of vertical Gabors (all equidistant from fixation)...
متن کاملThe preview benefit in single-feature and conjunction search: Constraints of visual marking.
Previewing distracters enhances the efficiency of visual search. Watson and Humphreys (1997) proposed that the preview benefit rests on visual marking, a mechanism which actively encodes distracter locations at preview and inhibits them afterwards at search. As Watson and Humphreys did, we used a letter-color search task to study constraints of visual marking in conjunction search and near-effi...
متن کاملIntegrating space and time in visual search: How the preview benefit is modulated by stereoscopic depth
We examined visual search for letters that were distributed across both 3 dimensional space, and time. In Experiment 1, when participants had foreknowledge of the depth plane and time interval where targets could appear, search was more efficient if the items could be segmented either by depth or by time (with a 1000 ms preview), and there were increased benefits when the two cues (depth and ti...
متن کاملHistory matters: the preview benefit in search is not onset capture.
Visual search for a conjunction target is made easier when distractor items are temporally segregated over time to produce two separate old and new groups (the new group containing the target item). The benefit of presenting half the distractors first is known as the preview effect. Recently some researchers have argued that the preview effect occurs because new stimuli capture attention. This ...
متن کاملOnset of background dynamic noise attenuates preview benefit in inefficient visual search
When certain distractors (old items) appear before others (new items) during an inefficient visual search task, observers exclude the old items from the search (preview benefit), possibly because their locations are deprioritized relative to the locations of the new items. We examined whether participants were able to ignore task-irrelevant changes in a scene (i.e., the onset of repetitive chan...
