THE ALTERNATION PROCESS IN BINOCULAR RIVALRY
Alternation frequency in binocular rivalry and relative dominance of stimuli in the right and left eyes are described in terms of an alternation model. The model is based on the assumption that the mean duration of the dominance of the stimulus in one eye is independent of the strength of this stimulus; the duration is assumed to be dependent only upon the strength of the stimulus in the contralateral eye. A provisional definition of stimulus strength is given. Evidence for assumptions and model is presented by a review of experimental literature on dominance and alternation in binocular rivalry, and by a number of experiments. Normal binocular fusion is considered.
