| Abstract: | The purpose was to compare the performance of normal and educable mentally retarded children on pattern recognition tasks. Pattern recognition was assessed by the administration of 96 pattern tasks which measured the ability of children to find: (a) duplicate patterns and same elements as presented in model pattern sequences; (b) opposite patterns and same elements as presented in model pattern sequences; and (c) duplicate patterns but different elements than presented in model pattern sequences. The normal and mentally retarded children were matched on mental age derived from individual and group intelligence tests. Results indicated significant differences in performance measures between groups and various pattern tasks. The data support the suppositions that: (a) mentally retarded children and normal children show the same type of progression through the hierarchical arrangement of pattern tasks; and (b) mentally retarded children show a slower progression through the hierarchy than normal children when matched on mental age. Educational implications from this study are discussed. |
