Interocular transfer of the motion after-effect is not reduced by binocular rivalry

Motion after-effects (MAEs) were measured intraocularly (adaptation, test stimuli to same eye) and interocularly (adaptation, test stimuli to opposite eyes) when (a) a rival stimulus caused perceptual suppression of the adaptation stimulus; (b) no rival stimulus was presented for the entire adaptation duration; and (c) non-rival adaptation was limited to the duration and adaptation stimulus was dominant in (a). Intraocular MAEs were greater than interocular MAEs; furthermore, both intraocular and interocular MAEs were similar following conditions (a) and (b) and reduced following (c). This pattern occurred with gratings of 1, 2 and 4c/deg, but not 8c/deg. Data are discussed in terms of mechanisms of rivalry and MAEs. © 1981.
