Abstract
After subjects scanned red stripes tilted clockwise off vertical and green stripes tilted equally but counterclockwise, vertical test stripes appeared tilted counterclockwise when red but clockwise when green. As the angle between scanned and test stripes was increased from 0° to 75°, the magnitude of the tilt aftereffect rapidly increased to a peak between 10° and 15° and then dropped close to zero at about 40°, a result consistent with narrowly tuned edge-sensitive channels.Keywords
