Localization and discrimination of “pop-out” targets
In parallel visual search, a target pattern "pops out" among distractors rapidly, requiring no effort, regardless of distractor numbers. The localization and discrimination of "pop-out" targets was investigated for this research note using similar multiple displays to those used in Sagi and Julesz's [(1985a) Science, 228, 1217-1219] and Folk and Egeth's [(1989) Journal of Experimental Psycholog...
متن کاملColor singleton pop-out does not always poop out: an alternative to visual search.
Folk psychology suggests that when an observer views a scene, a unique item will stand out and draw attention to itself. This belief stands in contrast to numerous studies in visual search that have found that a unique target item (e.g., a unique color) is not identified more quickly than a nonunique target. We hypothesized that this finding is the result of task demands of visual search, and t...
متن کاملTwo sources of error in pop-out localization
An odd-one-out stimulus, such as a vertical bar among horizontals, pops out from the background and is easily detected, but its location may be slightly ambiguous. Four observers were asked to pinpoint these stimuli on thousands of trials, in 5 x 5 and 9 x 9 arrays of Gabor patches. We found they made frequent errors toward neighbors of the target. Over a range of performance from 41% to 96% co...
متن کاملPriming of pop-out: I. Role of features.
We examined a visual search task, in which observers responded to the high-acuity aspect of a pop-out target (shape of an odd-colored diamond or vernier offset of an odd spatial-frequency patch). Repetition of the attention-driving feature (color or spatial frequency) in this task primes the pop-out; repetition of the high-acuity aspect (shape, vernier offset) does not. Priming of pop-out is du...
متن کاملVisual Singleton Detection (‘Pop-out’) is Mediated by Dimension- based Attention
The work reported in this chapter is concerned with a seemingly simple problem, namely: how an odd-one-out object, a single-feature target, is segmented from a background of homogeneous nontarget objects when the target-defining dimension is not known in advance, that is, when the critical dimension varies from trial to trial, resulting in cross-dimensional target uncertainty. Our work argues t...
