Do 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...
متن کاملThe time-course of pop-out search
Olds, Cowan and Jolicoeur [2000. Tracking visual search over space and time. Psychonomic Bulletin & Review (in press)] interrupted pop-out search by adding distractors to a display after a delay. They analyzed the response time distributions from conditions with different delays for interruption and showed that when pop-out search fails, its partially completed computations can be used to assis...
متن کاملSystem identification in Priming of Pop-Out
Inter-trial repetitions of a target's features in a visual search task reduce the time needed to find the target. Here I examine these sequential dependencies in the Priming of Pop-Out task (PoP) by means of system identification techniques. The results are as follows. Response time facilitation due to repetition of the target's features increases linearly with difficulty in segmenting the targ...
