Fig. 9.

Perceptual motion adaptation effects from motion stimuli presented on the liquid crystal display (LCD) monitor. Perceptual adaptation indexes (see materials and methods for definition) based on adaptation-induced changes in coherence and contrast sensitivity are plotted for the adapted direction (filled symbols and solid lines) and for the direction opposite to the adapted direction (open symbols and dashed lines). The vertical lines indicate 68% CI from bootstrap sample estimates. The different symbols represent the indexes obtained from 5 different subjects.
