title: Do rod signals control stimulus field prevalence in binocular rivalry?
abstract: We tested the hypothesis that rod signals mediate the effect of luminance on field prevalence in binocular rivalry. Results show that (1) field prevalence saturates at a luminance that is less than 0.001 that of the value reported for rod saturation, (2) the spectral sensitivity inferred from the prevalence-luminance relationship is not scotopic, and (3) the prevalence-luminance relationship does not behave univariantly under all chromatic conditions. We conclude that rod signals alone do not control field prevalence.
