To study the development of static behavior of disabled schoolchildren, 20 items of behavior were checked in 145 children from the two schools for the mentally retarded. The items are kneeling, cross-legged sitting, legs forward bending and touching the toes, opening toes, hands together on the back, etc.
Each item of behavior was given 1 point if succeeded or 0 if failed. The items were 20 in total, so 20 points were given if all items were succeeded.
The average score for senior high school students was significantly higher than for junior high school students, and that of elementary schoolchildren was the lowest. But there was no significant difference between male and female. The static behavior seems to be affected more seriously by disability than by sex difference.
The static behavior of disabled schoolchildren developed sequentially from a kind of coordination to the intellectual one.
