<p>(A) Stimuli presented in the experiment. In the CFS trials, flanking stimuli presented to the non-dominant eye of the observers in the flanked condition were perceptually suppressed from awareness by the CFS stimuli that were simultaneously presented to their dominant eye. Thus, in any given CFS trial, only the target grating pattern and the CFS stimuli were perceptually visible. Note that the actual contrast of the stimuli presented to their non-dominant eye was much lower than that illustrated here. (B) Contrast thresholds (in log scale) in the unflanked and flanked conditions as a function of CFS (n = 4). Error bars indicate the standard errors of the means.</p
