Hemi-retinal attention under conditions of color rivalry

Human Ss viewed stimulus arrays of color patches such that two instances of color rivalry were simultaneously present. That is, two patches of different color were present, one each in each of the left halves of the two ocular fields, and at the same time, rival patches were also present in the two right halves. As would be expected, binocular percepts often corresponded to predominance of one or the other of the two eyes. On other occasions, however, Ss reported percepts which indicated simultaneous predominance of the nasal halves or, more often, of the temporal halves of the two retinas.
