Examining perceptual and conceptual set biases in multiple-target visual search.
Visual search is a common practice conducted countless times every day, and one important aspect of visual search is that multiple targets can appear in a single search array. For example, an X-ray image of airport luggage could contain both a water bottle and a gun. Searchers are more likely to miss additional targets after locating a first target in multiple-target searches, which presents a ...
متن کاملMemory processes in multiple-target visual search.
Gibson, Li, Skow, Brown, and Cooke (Psychological Science, 11, 324-327, 2000) had participants carry out a search task in which they were required to detect the presence of one or two targets. In order to successfully perform such a multiple-target visual search task, participants had to remember the location of the first target while searching for the second target. In two experiments we inves...
متن کاملAttentional set interacts with perceptual load in visual search.
In the present study, we examined the hypothesis that perceptual load is the primary factor that determines the efficiency of attentional selection. Participants performed a visual search task under conditions of high- and low-load. In line with the perceptual load hypothesis, presenting conditions of high- and low-load in separate blocks of trials resulted in processing of to-be-ignored stimul...
متن کاملVisual search has memory: Evidence from multiple target search
Recent studies have proposed two opposing models regarding the function of memory in inefficient visual search, a memory-driven model and a memory-free model. Horowitz and Wolfe (2001) examined the reaction time x n function in a multiple target search task: Participants were required to respond whether there were at least n targets present in the display or not. They demonstrate the positive a...
متن کاملContextual learning of multiple target locations in visual search
In visual search, detection of a target is faster when a layout of nontarget items is repeatedly encountered, suggesting that contextual invariances can guide attention. Moreover, contextual cueing can also adapt to environmental changes. For instance, when the target undergoes a predictable (i.e., learnable) location change, then contextual cueing remains effective even after the change, sugge...
