Positional averaging explains crowding with letter-like stimuli.
Visual crowding is a breakdown in object identification that occurs in cluttered scenes, a process that represents the principle restriction on visual performance in the periphery. When crowded objects are presented experimentally, a key finding is that observers frequently report nearby flanking items instead of the target. This observation has led to the proposal that crowding reflects increa...
متن کاملTitle: Crowded Letter and Crowded Picture LogMAR acuity in Children with Amblyopia: a quantitative comparison. Sub-Title: Comparing crowded letter and picture acuity in children with amblyopia. Authors:
Aims: Clinically, picture acuity tests are thought to overestimate visual acuity (VA) compared with letter tests, but this has not been systematically investigated in children with amblyopia. This study compared VA measurements with the LogMAR Crowded Kay Picture test to the LogMAR Crowded Keeler Letter acuity test in a group of young children with amblyopia. Methods: 58 children (34 male) with...

متن کاملDetecting distortions of peripherally presented letter stimuli under crowded conditions.
When visual features in the periphery are close together they become difficult to recognize: something is present but it is unclear what. This is called "crowding". Here we investigated sensitivity to features in highly familiar shapes (letters) by applying spatial distortions. In Experiment 1, observers detected which of four peripherally presented (8 deg of retinal eccentricity) target letter...
متن کاملCan Hidden Variables Explain Correlation?∗
Correlations arise naturally in non-cooperative games, e.g., in the equivalence between undominated and optimal strategies in games with more than two players. But the non-cooperative assumption is that players do not coordinate their strategy choices, so where do these correlations come from? In coin tossing, correlated assessments are usually understood as reflecting the observer’s ignorance ...
