Two 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 کاملLocalization 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 کاملDo People “Pop Out”?
The human body is a highly familiar and socially very important object. Does this mean that the human body has a special status with respect to visual attention? In the current paper we tested whether people in natural scenes attract attention and "pop out" or, alternatively, are at least searched for more efficiently than targets of another category (machines). Observers in our study searched ...
متن کاملCueing and pop-out
We describe experiments on the dynamics of pop-out from orientation. Target lines at an oblique orientation and orthogonal background elements were presented with various onset delays, and subjects' performance in target detection was measured. Detection rates increased for short delays compared to synchronous stimulus presentation, with a maximum at delta t = 30-60 ms. Control experiments show...
متن کاملFalse pop out.
A single, unique target often pops out quickly and efficiently from a field of homogenous distractors in visual search. Pop out has helped shape theories of visual attention and feature integration as well as to identify basic features in human vision. Here we report a new phenomenon, false pop out, wherein one of the homogenous distractors competes with the singleton target to pop out, perhaps...
