COMPARATIVE STUDIES OF DOWN'S SYNDROME AND PHYSIOLOGICAL MENTALLY CHILDREN OF ABILITY FOR FIGURE-COPYING

Abstract

In this study, the performances on copying the figures are compared between children with Down's syndrome and physiological men tally retarded children. We have selected 17 Down's syndrome children and 12 physiological mentally chidren children, matched for MA, CA and IQ. The mean MA for Down's syndrome were 5.1 yr (range 3.0 to 8.7) and thet for physiological mentally retarded children 5.7 yr (range 3.6 to 8.5) respectivley. The mean age of Down's syndrome children was 11. 10 yr (range 9.2 to 14.11) and of physiological mentally retarded children 12.1yr (range 9.4 to 14.8) respectively. The mean IQ for Down's syndrome children was 42.24 (range 30 to 65) and the mean IQ for physiological mentally retarded children was 45.33 (range 33 to 63) respectively. None of these group differences were significantly observed. Examination for copying the six figures performed without time limit. The results were shown as follows; with regard to the mean copying score, there were no significant differences between Down's syndrome and physiological mentally retarded children. It was shown the tendency that children with Down's syndrome have a little better scored than physiological mentally retarded children, regardtng with the copying ability for figure composed with oblique lines.
