Abstract
The purpose of the present study was to examine the relation between the recognition and the ability of the motor regulation. To clarify this problem an experiment was designed employing the standing broad jump. The subject was instructed to jump as far as possible, and then he was asked to jump its "half" distance. Beforehand the recognition level of "half" concept in the length was investigated toward all subjects. The subjects were 45 normal children with CA from 2:10 to 5:5 and 47 retarded children with MA from 2:10 to 5:4. The results were as follows: (1) Generally speaking, both the normal and the retarded who acquired the higher recognition level showed the better ability of the motor regulation. (2) The subjects who did not recognize the "half" concept in the length at all (level 1) could regulate the distance of their standing broad jump somewhat. (3) On the ability of the motor regulation in the same recognition level the retarded was inferior to the normal. The additional examination was designed to study the ability of the visual motor regulation by setting up the objective line. The results were as follows: (1) The older subjects showed the better ability of the visual motor regulation. (2) On the ability of the visual motor regulation, the retarded was inferior to the normal. (3) In the same age, the subjects who acquired the higher recognition level showed the better ability of the visual motor regulation.
