||Localizing contours defined by more than one attribute.
Conducted 2 experiments with 3 adults to test how information from different attributes is combined to localize contours. In Exp 1, the apparent position of a contour defined by one attribute was measured while a contour defined by another attribute was presented beside it. Interactions were found between all pairings of luminance, color, motion, and texture. These results suggest that the information associated with each contour is integrated at a common site. In Exp 2, the precision of localization was measured for contours defined by 1, 2, or 3 attributes (combinations of luminance, color, and texture). The improvement in precision with additional attributes again supports an integration of contour information at a common site prior to a decision of localization.
