Binocularly perceived phase as a function of interocular signal ratios for the four dichoptic pairs.

<p>Results of the seven observers (N1–N7) and their averages are shown in separate panels. In each panel, the vertical axis represents perceived phase of the cyclopean grating, the horizontal axis represents interocular signal ratio (Dominant eye/nondominant eye); the four kinds of symbols represent data for four dichoptic pairs: ‘○’, first-order stimuli; ‘•’, second-order stimuli with correlated carrier in two eyes; ‘▴’, second-order stimuli with anti-correlated carries in two eyes; ‘▪’, second-order stimuli with uncorrelated stimuli. The colored solid lines represent prediction of a modified gain control model (see data fitting in the Methods part). The horizontal line in the middle of each panel indicates expected output when the perceived phase is zero. Error bars represent standard errors.
