本研究は小学校児童が学校場面においてあらわした日常の攻撃的行動と投影検査にあらわれた攻撃的内容との関連について研究するのが目的であつた。投影検査にあらわれた攻撃的内容をみるために児童の友人についての記録,TAT,HSCTの3つについて検査し,児童の学校場面におけるあらわな攻撃的行動は教師によって評価された。この結果を検討するとあらわな攻撃行動と児童の友人についての記録内容にもられた攻撃性との間に意味ある関連を見出した。しかし児童のあらわな攻撃性の強さとTATに対する空想的攻撃的テーマーの頻数との問に関連が見出せなかった。さてあらわな攻撃性とHSCTとの関連については,攻撃的行動展開の両極端の児章達はその中間の攻撃性と評価された児童達よりもHSCTにおいてより多くの攻撃的テーマーをつくった。かかる非直線的関連はBac(2)やSears(8)が人形劇を用いて人.間問の攻撃性と空想的攻撃について研究した結果とも一致するところであり,投影検査におけるこの方面の研究に一つの光明を見出すことができた。

The purpose of this study is to investigate the nature of the relationship between overt aggression in the normal classroom behavior of children and the aggressive content they produce in their TAT, in their Hostile Sentence Construction Test (HSCT) protocols and in their compositions about their classmates. Previous studies and clinical theory in this area suggest specific hypotheses for investigation. These hypotheses may be stated as follows : 1) The relationship between aggressive content in the TAT and their compositions, and overt aggression, will be positive and linear. 2) There will be a curvilinear relationship between the aggressive content in the HSCT and overt aggression. Hypothesis I is based on a common assumption that the thematic material in general projects overt behavior in actual situation. Hypothesis 2 is due to our assumption that hostile content in the HSCT, as in the Rorschach, may be an expression of covert hostile tension. Two projective tests, TAT and HSCT, were administered to one hundred and twenty children between eleven and twelve years of age. Then they were asked to write freely the in relations with their friends. Their overt aggressions were rated by their classroom teachers. Results : 1) There was a significant relationship between the rating of agrresions which was expressed in children's compositions and the rating of their overt aggresions. 2) There was no significant correlation between the hostile content they produced in their TAT and their overt aggersions. 3) The relationship between the HSCT and their overt aggressions was curvilinear. In other words, children rated at both extremes on diplay of overt aggressions, i..e, very aggressive or very non-aggressive, proved to be more aggressive in the HSCT than those children who rated as moderately aggressive.
