[An analysis of individual differences in reading abilities of the partially sighted children (author's transl)]

The purpose of present study was to analyze the intra- and inter- individual differences in reading abilities of the partial-sighted children. The Ss, consists of 79 normal-sighted children and 20 partial-sighted ones, were given 20 tests by the E. In order to analyze the intra-individual differences by the ratio of individual scores obtained, T scores were converted into Z scores after obtaining each T score of 20 tests. The partial-sighted were significantly inferior to the normal-sighted in 7 tests. By both cluster analysis and Q-technique, the clusters were found to be unstable in terms of the discrimination of the partial-sighted from the normal sighted. 2 groups, however, were completely discriminated by the method of multiple correlation coefficient of which ratio was .839.
