Emotional Faces in Peripheral Crowding
Crowding effect refers to the deficit in identifying viewed targets, such as letters, numerals, line segments, or grating patches, when other shapes are nearby. This effect is reduced when distractors have a different color, contrast, or binocular disparity than that of the target. With feature singleton targets, the crowding effect decreases dramatically with an increasing number of distractors for both simple orientation and more complex letter identification tasks . With a target that is not a salient feature singleton, however, the increasing number of distractors worsens rather than improves the perception of the target .
