抄録: We have two chapters in this study. The details are as follows; Chapter 1. This chapter is the sequel to our treatise reported in the preceding Bulletin of The Faculty of Education Univ. of Tokyo Vol. 15. In that Bulletin, we hypothesized that the effect of noises on psychological performance was not merely inhibitory but also accelerating, designated them as "inhibitory effect" and "accelerating effect". The main purpose of this chapter is to investigate these two effects, in case of performing Intelligence-Tests which has 5 intellectual factors from simplicity to complexity. Experimental conditions and procedures are as follows ; Test : Intelligence-Test, known as Todai A-S form. Noise conditions : Control group-about 40 dB(A), Experimental group-White noise 80 dB(A), produced by Noise Field Generator, placed at the center of the experimental rooms. Grouping: 3 groups. Gl-Control. G2-Experimental, doing the test in Usual Sequence, G3-Experimental, doing the test in Reverse Sequence. Subjects : The first and the second year Junior High School, about 50 members in each group. The main findings of this chapter were shown under. Concerning the complex intellectual factors in intelligence-test, "inhibitory effect" came first which was shown in Reverse Sequence Group : G3. But in the simple intellectual factors, " accelerating effect" had a tendency to come first, which was same as Kroeperin-Test composed of mathematical computation. Anyway two effects mentioned the above had different influence upon intellectual factors by the degree of complexity. Chapter 2. In this chapter, we investigated the effect caused by exposure to the music, by carrying out experimentally on 173 male and 173 femail junior high school pupils engaged in some intellectual performance. The findings of this chapter were as follows ; 1. The intellectual performance in the case of the quiet condition was more efficient in comparison with that of the music exposure, 2, The inefficiency under the music was not related to the degree of the undesirability against music, but related to the degree of the unfamiliarity with music.
