Visual search has memory.
By monitoring subjects' eye movements during a visual search task, we examined the possibility that the mechanism responsible for guiding attention during visual search has no memory for which locations have already been examined. Subjects did reexamine some items during their search, but the pattern of revisitations did notfit the predictions of the memory less search model. In addition, a lar...
متن کاملAging, memory and visual search.
Potential age-related differences in the memory processes that underlie visual search are examined in the present study. Using a dynamic, gaze-contingent search paradigm developed to assess memory for previously examined distractors, older adults demonstrated no memory deficit. Surprisingly, older adults made fewer refixations compared to their younger counterparts, indicating better memory for...
متن کاملQuantifying peripheral and foveal perceived differences in natural image patches to predict visual search performance.
Duncan and Humphreys (1989) identified two key factors that affected performance in a visual search task for a target among distractors. The first was the similarity of the target to distractors (TD), and the second was the similarity of distractors to each other (DD). Here we investigate if it is the perceived similarity in foveal or peripheral vision that determines performance. We studied se...
متن کاملVisual search for category sets: tradeoffs between exploration and memory.
Limitations of working memory force a reliance on motor exploration to retrieve forgotten features of the visual array. A category search task was devised to study tradeoffs between exploration and memory in the face of significant cognitive and motor demands. The task required search through arrays of hidden, multi-featured objects to find three belonging to the same category. Location content...
متن کاملOnline Information Search: Differences between Goal-Directed and Experiential Search
travelers’ use of the Internet as an information source has been the subject of research in the past. Most studies focus on the search process; however, the influence of the actual search goal on search behavior has been neglected. travelers’ interactions with a website may depend on whether they search for precise factual information or rather stimulus driven and unplanned. this article provid...
