This study aimed to clarify the characteristics of defensive self-presentation of school children on the basis of its relation to grade (4th, 5th and 6th grade), sex, and the target person (homeroom teacher, intimate friends, non-intimate friends). We asked 95 elementary school children to evaluate using intention of three types of defensive self-presentation, including "apology", "account", and "selfhandicapping". The results of our investigation showed the following: 1) 5th grade children tended to use "self-handicapping" compared to 4th and 6th grade children, 2) girls tended to use "apology" more than boys, and not to use "account", 3) school children tended to use "apology" and "self-handicapping" and not to use "account", when the target person was "intimate friends".
