Abstract(in English) We examined reaction times (RTs) during smooth pursuit with different retinal eccentricities and stimulus velocities. Experiment 1 showed that the RTs increased with increasing the retinal eccentricity. As of effects of the stimulus velocities, there were large differences between 5° and 10°/sec of the stimulus velocities. Moreover, the participants who showed slow RTs showed small velocity errors. In Experiment 2, using a stimulus display similar to that used in Experiment 1, we examined RTs during stationary fixation on a display of moving stimuli that simulated the retinal image velocity in Experiment 1. The results showed that the RTs during smooth pursuit were slower than those during fixation, suggesting that RTs during smooth pursuit reflect not only the retinal image velocity but also the tradeoff between pursuit accuracy and RT.
