抄録	Minimum temporal thresholds(Tmin)for discriminating motion direction were measured in various conditions. The results of Experiment 1 showed that Tmin for the change from a stationary pattern to a moving pattern was shorter than that for the abrupt appearance of a moving pattern. The time needed to process the pattern explained this difference. The results of Experiment 2 showed that Tmin for the change from a stationary pattern to a moving pattern was shorter than that for the directional change of a moving pattern. Furthermore,Tmin for discriminating a directional change with a 90 deg difference was shorter than that of 45 and 135 deg. In addition,an anisotropy in discriminating motion direction was observed between oblique-upward and oblique-downward directions. The validity of mathematical models that explain these results was discussed.
