In this study, as the core of imitative behavior, interest and curiosity were chosen. Behavior that were supported to express interest and curiosity were closely watched and they were studied in relation to development of imitative behavior. The followings are the results in summary of the observations of 12-24 months old children in a nursery.
1) In the scene of playing with playmates and nurses, children over 18 months were more often seen to imitate than children under them, and in the same scene, children tended to imitate elder models' behaviors than themselves.
2) In the scene that children were playing with their brothers and sisters, two types of behaviors which seemed to express their interest and curiosity were often seen : they are followings, the behavior which was not same but closely resemble to their brothers' and sisters', and the behavior that children tried to take or took actually what their brothers and sisters had. It seems that they could not imitate, but showed their interest and curiosity by these behaviors. From this I think that these behaviors are in the previous stage to imitative behavior.
3) Common to the scene of playing with playmates and nurses, the scene of having meals and the scene of playing with brothers or sisters, before or after imitative behaviors were observed, children were attracted by models' behaviors and stared at them. This showed that before or after they imitated, behaviors that were supported to express interest and curiosity were seen.
