Irrelevance of local position information in visual adaptation to random arrays of small geometric elements.
Experiments were carried out to test whether spatial relationships between local pattern features are important in the production of pattern-specific visual adaptation effects. Evidence was found for sensitivity to the shape of local pattern features, but not to their relative positions. These findings are contrasted with recent results for texture discrminination where the visual system can make use of local position information.
