From Wikipedia, the free encyclopedia
Visual search is defined by the ability to consciously locate an object (target) amongst a complex array of stimuli (distractors) and has been extensively studied over the past 40 years. Practical examples of this can be seen in everyday life such as picking out a product on a supermarket shelf, animals searching for food amongst piles of leaves, trying to find your friend in a large crowd of people and playing visual search tasks such as ‘Where’s Wally’. Many visual search paradigms have used eye movements as a means to measure the degree of attention given to stimuli. [1] [2] However, vast research to date suggests that eye movements move independently of attention and therefore is not a reliable method to examine the role of attention. Much behavioural research focusing on reaction time has dominated this field of research and to date is still extremely reliable. Much of the previous literature on visual search uses reaction time (RT) in order to measure the time taken to detect the target amongst its distractors. An example of this could be a green square (target) amongst a set of red circles (distractors).
