Setting up the target template in visual search.
Top-down knowledge about the target is essential in visual search. It biases visual attention to information that matches the target-defining criteria. Extensive research in the past has examined visual search when the target is defined by fixed criteria throughout the experiment, with few studies investigating how subjects set up the target. To address this issue, we conducted five experiments...
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 کاملTarget-distractor discriminability in visual search.
Previous research has demonstrated that discriminability of target and background elements has powerful effects on visual search performance. Typically, discriminability has been manipulated between blocks or subjects, allowing subjects to anticipate the discriminability in advance of each trial, and the results, therefore, have been consistent with a wide range of models. Two experiments are r...

15 صفحه اولAge, target-distractor similarity, and visual search.
Younger and older adults were asked to find a single target in both feature- and conjunction- search conditions. Display size varied between 2 and 8 items, and target-distractor similarity ranged from relatively low to high levels. The accuracy data indicated that older adults had particular difficulty finding targets in high-similarity conjunction-search displays containing a large number of d...
