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 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 کاملReaction time distributions constrain models of visual search
Many experiments have investigated visual search for simple stimuli like colored bars or alphanumeric characters. When eye movements are not a limiting factor, these tasks tend to produce roughly linear functions relating reaction time (RT) to the number of items in the display (set size). The slopes of the RTxset size functions for different searches fall on a continuum from highly efficient (...
متن کاملalterations of visual reaction time and short term memory in military radar personnel.
radar transmitters emit high-power radiofrequency radiation by creation of a high-voltage and high-frequency alternating electrical current.health effects of occupational exposure to military radar were investigated. visual reaction time was recorded with a simple blind computer-assisted-visual reaction time test. to assess the short-term memory, modified wechsler memory scale test was performe...
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...
