On the spread of suppression and binocular rivalry

Do depth shifts resulting from an interocular delay in stimulation result from a breakdown of binocular fusion?

“…This finding is consistent with that reported by Kaufman (1963). He found no binocular rivalry with stimulus exposures of 50 msec in duration.…”

Visibility of an afterimage in the presence of a second afterimage

“…Binocular rivalry between two optically stabilized images has been reported by Krauskopf and Riggs (1959) and Ditchburn and Pritchard (1960). Kaufman (1963) and Levelt (1965), using nonstabilized images, also found that rivalry depended on the relative positioning of the two images. However, none of these studies compared dichoptic results with monocular results in the same way as in the present afterimage study, and so it is impossible to compare the possible effect of orientation differences across studies.…”

Binocular rivalry occurs without simultaneous presentation of rival stimuli

“…266 This is an almost identical description to that given by Kaufman (1963), who controlled the stimuli with more precision by using a strobe lamp. His rival display consisted of gratings of orthogonal lines illuminated for 50 msec at 2 Hz with a 21O,000-lx source.…”
