 note = {application/pdf, 紀要論文, The purpose of this study was to examine the development of self-assertion at two, two-and-a-half and three-years-old, and to clarify their parents’ recognition of their negativism. 69 parents with one-year-olds, who were the firstborns, enrolled in this longitudinal study, and they answered the questionnaire by post. Three factors were obtained by using factor analysis, and those were named as a clear, a skillful, and an unskillful-self-assertion. All types of self-assertion scores rose with aging; A skillful self-assertion greatly progressed at two-and-a-half, and a clear self-assertion increased at three-years-old; An unskillful self-assertion did not decrease at all, and a high score was kept. About 80％ of parents felt the negativism was unavoidable because it was a developmental stage, and they evaluated it as both positive and negative. Parents regard their children’s self-assertion as important, and tried to develop it, however, they did this through trail and error. It is necessary to develop a new program (not only family education but also preschool education) to refine the self-assertions corresponding\
 to the changes in Japanese children.},
