The object of this study is to analyze the effects of the special individual guidance of the little children with mental and emotional handicaps. The subjects of this study were 18 children of the Hokudai Yojien' (Hokkaido University Kindergarten). They were divided into 2 groups, experimental and control. To the experimental group, special individual guidance was given for a month during the summer vacation. Some of the facts found out by this study are as follows : (1) Conspicuous effect of the individual guidance could not be recognized as a whole. (2) The individual guidance had no effect on the intellectual development of the children with handicaps, having some effect on their behavior and attitude. (3) The development of the manual and occupational ability was very remarkable in the experimental group, but concerning the total scores of social maturity test given to both groups before and after the experiment, the increase of the score inthe control group was significantly higher than in the experimental group. This shows that the modification of the program of the individual guidance is necessary.
