Abstract

|
|
With the materials of measurement of reaction time in the Holtzman inkblot cards it was attempted to assess the reaction pattern and variances which determine the reaction time of normal Korean adolescents.
The results of this study were as follows:
1. In the analysis of variances of reaction time it was found that the difference between cards and between subjects were statistically significant at 0.01 level.
2. The difference of variances of reaction time between sex was significant at 0.01 level but the interaction variance was not significant.
3. The hypotheses that the simple and the complex variables of the silhouette, the internal form, the insular and the symmetry of the form of the cards would effect the dependent variables to the reaction time were not proved but the hypothesis that the chromatic and the achromatic variables of the cards would not effect the dependent variables was proved.
4. According to the similarity of reaction times, the cards could be classified into five groups (verified with CR test) in each sex.
5. In the trend analysis of variances of reaction time the linear regression was significant at 0.01 level.
6. According to the linear functions of the cards and the reaction time it was found that in the male subjects Rp was 2.5 and LT was 15.3 and in the female subjects Rp was 2.3 and LT was 10.4.
As a summary it can be said that the variation of the Holtzman card situations as a -whole Iwould effect the interaction variance to the reaction time.
