Abstract: Hull's and Smoke's methods for the study of concept formation were adopted which, included 4 tests: recognition, generalization, identification and reproduction. The subjects in this experiment were the same as those in the previous experiment on recognition. It was found that there are also 3 types of developmental curves: 1) recognition and generalization negatively accelerated ; 2) identification positively accelerated ; 3) concepts of figures——simple accelerated curve. Correlations between different indices on generalization and recognition of different Chinese characters were significant. The results support the hypothesis that the ability of generalization is one of the basic factors which promote the recognition of Chinese characters.
