Vision: Filling in and pop out
نویسنده
چکیده
The 'pop out' of a distinctive element embedded in a regular pattern, and the 'filling in' of a blind spot, are dramatic manifestations of the way context affects visual perception. Recent studies shed light on the neurophysiological bases of these phenomena.

Texture filling-in and texture segregation revealed by transient masking
When a texture pattern was briefly presented followed by a small annular mask, it was found that the central area of the texture was strongly suppressed within the mask. Analogous to filling-in of brightness in a uniform luminance area (Paradiso, M. A. & Nakayama, K. (1991) Vision Research, 31, 1221-1236), this phenomenon demonstrates filling-in of texture; the texture area was unperceived beca...
متن کاملAn adaptation-induced pop-out in visual search.
The present study demonstrates that an object embedded in an array of identical objects can pop-out. Dependent on the stimuli preceding the search display, local (chromatic) adaptation causes an identical object to pop-out because it appears to have a colour (Expt 1) or brightness (Expt 2) that is slightly different from the colour and brightness of the other objects in the display. Experiment ...

متن کاملOrientation search is mediated by distractor suppression: Evidence from priming of pop-out
In search for a singleton target, performance is considerably improved when the target and distractors repeat than when they switch roles, an effect called priming of pop-out or PoP (Maljkovic & Nakayama, 1994). Although this phenomenon has been replicated across a variety of dimensions, orientation PoP has proved to be volatile. Recent research has shown that target activation and distractor i...
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...
