We investigated the effect of white noise, continuous and intermittent, upon Uchida-Krae-pelin Test. Subjects were 230 male and 230 female junior high school students. They took the test under three different conditions, namely, ordinary level of room noise (about 45 dBA), continuous white noise and intermittent one (both; about 70dBA). The main findings of this study were as follows; 1. White noise had inhibitory effect upon the performance of the test, especially in the first period. 2. It seemed that intermittent white noise was more inhibitory than continuous white noise, but the difference was not statistically significant. 3. Inhibitory effect of white noise was clearly observed in those subjects who had the lowest skillfulness in performing the test.
