Stabilized images: Functional relationships among populations of orientation-specific mechanisms in the human visual system

The relationship between sighting dominance and the fading of a stabilized retinal image

“…The order of eye of stimulus. The absence of orientation-specific effects in our data contradicts the results of other studies of stabilized image fading (Brown et al, 1973;Cosgrove et al, 1972;Schmidt et al, 1972;Schmidt et al, 1971;Sharpe, 1972;Wade, 1972Wade, , 1973aWade, , 1973b. Generally, it has been reported that horizontal and vertical lines exhibit more perceptual stability as stabilized targets than do lines of oblique orientations.…”

Contrast-dependent interaction between steadily fixated lines

“…Similarly, Wade (1976) found that the visibility of the afterimage of a circular grating was increased by the concurrent presentation of a surround grating of the same orientation if both were seen by the same eye. Interactions between lines of similar orientation have also been reported by Schmidt, Cosgrove, and Brown (1972) for optically stabilized lines viewed after preadaptation to gratings in the same or in different orientations. Prior viewing of a like-oriented grating increased the frequency of fading of the stabilized line, which the authors suggested could have been due to selective adaptation of orientation-specific pattern elements in the visual system.…”
