Abstract: This article deals with an experimental research on 3 to 6-year-old children's ability to control their behavior under adults' oral directivesin different activities. The results indicate: 1. It is easy for pre-school children to control their behaviorto interesting activities. 2. Adults' clear and concrete directives and good orgnization of thechildren's activities have no effect on 3-year-olds' ability to controltheir behavior, but do affect 4 to 6-years-olds, with the effect becomingstronger as age increases. 3. Enhancing the effect of motives simply with oral directives byadults exerts no effect on children's ability to control their behavior inall the age groups but combining motive with role-situation obviouslyaffect children's behavior contral. The above results showed that children's conscious control overbehavior develops gradually. In order to raise the children's ability tocontrol their behavior, various effective measures must be taken.
