A shift in the perceived simultaneity of adjacent visual stimuli following adaptation to stroboscopic motion along the same axis.

Adaptation to stroboscopic motion affects the perceived temporal order of two adjacent stimuli presented along the same axis. The extent of shift appears to be independent of the duration of adaptation and under the conditions studied was 3-6 msec in a direction consistent with a cancellation of the motion aftereffect. There was no effect upon the locus of simultaneity when adapting stroboscopic motion was orthogonal to that of the test stimulus.
