| Abstract(in English) | It has been reported that detection sensitivity for color stimuli was improved during smooth pursuit eye movement compared to the sensitivity during fixation (Schutz, et al,. 2008). Color- and luminance-motion stimuli were processed by different mechanisms, such as luminance and isoluminance motions. Isoluminance motion is modulated only by color. Here, we assumed that there are also differences in the effects of smooth pursuit eye movements on discrimination thresholds for motion direction presented by color and luminance stimuli. Our results showed that the sensitivity for slow motion stimuli was reduced during smooth pursuit especially for luminance stimulus. The sensitivity for fast motion wasn't influenced by the pursuit condition and the fixation condition. This implies that the mechanisms with increased, detection sensitivity for color stimuli during smooth pursuit eye movements do not contribute for the improvement of motion-direction discriminations. |
