従来多くの心理学者によってなされてきた点を用いた形態把握の実験結果は,知能(I.Q.)と非常に関係があるといわれている。この実験においては,正常者とろう者に点を用いた形態把握の実験を個人差研究の観点から企図し,その結果を発達的に比較検討せんと試みたものである。そこで得た結果を述べれば次の如くである。1.年令が上になる程,この実験結果の得点が良くなる傾向がある。2.学業成績のよい者は,この実験の結果もよい。学業成績の悪い者程,実験結果も悪くなる。3.I.Q.のよい者は,この実験の結果も良い。4.正常者の実験結果とろう者のそれとの間には,かなりの差がある。5.正常者の実験結果が,ろう者のそれよりも遥かによい。

Previously reported literatures on the study of the apprehension for configurations using dots tell us a close relation with I. Q. In the present study, both normal and deaf persons were tested with apprehension for configurations using dots and attempts were made to examine and study the results by development or age, and to find differences between the process of the apprehension for configurations of the normals and that of the deafs. Results were as follows : 1. Older persons showed higher score. 2. Scores were in parallel with the grades of the Hiroko tests. 3. Scores were in parallel with the I. Q. of tests. 4. Remarkable difference was found between the scores of the deaf and normal persons. The normal did much better than the deaf. From the above results, it can be seen that there is a considerable inter-relation between the quality of dot configuration apprehension and the intellect. Therefore this experiment using only visual materials may be used as an index of predicting the intelligence of the deaf.
