Appendix 1—figure 9. Perceptual mixtures: percepts that feature parts of both eyes' images.

Each plot uses a different measure to quantify the reported prevalence of perceptual mixtures for individual observers. Each disk corresponds to one observer. Data from the two observers that are indicated in red here were not included in the analyses for any of the other figures in this paper, because those observers scored high on all three indices of the prevalence of perceptual mixtures.
