Abstract
Various scoring systems on Bender-Gestalt test (BGT) have been devised. It seems that Pascal and Suttel (P & S) scoring system in them has been applied many times because it is rather objective. But it is said that it has too many factors to score easily. Koppitz published her scoring system which modified the P & S system for younger children. These scoring systems may respectively have some problems from the view point of development. The purpose of this study is to compare the P & S scoring system with the koppitz system applied to the same data, and to discuss how they acquire the developmental process of BGT and which is more suitable to catch it.
Subjects are consisted of 266 boys and 211 girls aged 5 to 17.
The following are the results of testing. First, the scores of both P & S's and Koppitz's decrease remarkably between 5 and 6 years. Therefore, it seems that the visual-motor function makes rapid development in these years. Next, the score of Koppitz's reaches a plateau at the age of 9, while that of P & S's decreases gradually even to 17 years. Koppitz's scoring system is found available to catch roughly the developmental change of BGT in the age range of 5-9 years, but insufficient to catch a qualitative change of development reflected on BG T. P & S's scoring system is more efficient than Koppitz's system, because the former can catch the qualitative change of development more in detail, even though it has too many factors to score easily.
