相対運動検出機構における順応効果

抄録

The effect of adaptation at the level of relative motion on the motion aftereffect (MAE) was examined. In experiment 1,MAE induced by surrounding motion was tested by measuring the MAE duration. In experiment 2,MAE was measured by the nulling technique, with adapting and the test stimuli presented in the same area. In both experiments, effects of adaptation at the relative motion level was clearly found. These results indicate the existence of adaptation of relative motion detecting mechanisms and its crucial role on MAE, supporting the idea that MAE simultaneously reflects adaptation both at the local and the relative motion processing levels.
