Crowding: Including illusory conjunctions, surround suppression, and attention.
This special issue of Journal of Vision is devoted to ‘‘Crowding,’’ a failure of object recognition. An object is ‘‘crowded’’ when clutter jumbles its appearance, making it impossible to identify. Clutter impairs perception of objects. As every child knows, Waldo is hard to find. Long-range effects of non-overlapping distractors can alter the appearance of an object, making it unrecognizable. A...
متن کاملCategorization influences illusory conjunctions.
Illusory conjunctions (ICs) provide evidence for a binding problem that must be resolved in vision. Objects that are perceptually grouped are more likely to have their features erroneously conjoined. We examined whether semantic grouping, determined by category membership (letter vs. number), also influences illusory conjunction rates. Participants were instructed to detect an "L" or a "7" amon...
متن کاملShape Recognition and Illusory Conjunctions
A bs t rac t and-egg problem can be solved by using a cooperative computation in a parallel network. The computation performs a parallel, iterative search which settles on both the reference frame and the shape description at the same time. One way to achieve viewpoint-invariant shape recognition is to impose a canonical, object-based frame of reference on a shape and to describe the positions,...

متن کاملA measurement theory of illusory conjunctions.
Illusory conjunctions refer to the incorrect perceptual combination of correctly perceived features, such as color and shape. Research on the phenomenon has been hampered by the lack of a measurement theory that accounts for guessing features, as well as the incorrect combination of correctly perceived features. Recently, several investigators have suggested using multinomial models as a tool f...
