Fig. 5.

From Experiment 2, results based on a subset of the conditions – those when the cueing ring was synchronized with inward motion (purple symbols) and those when it was synchronized with the red (red symbols). The best relative timing between the color and motion is determined by fitting a capped cosine to the data, and extracting the timing of the peak. For each observer, the resulting best in → red interval is close to zero, whereas without the ring (black symbols, data from comparable stimulus of Experiment 4) the best in → red interval is greater than 100 ms. Psychometric functions for all the ring timings are displayed in Appendix A. (For interpretation of the references to color in this figure, the reader is referred to the web version of this article.)
