Data suggest an ability to use concrete-operational reasoning is not required for doing complex arithmetic, even though it may be necessary for learning these arithmetic skills. (Authors)

This study investigated the relationship between giftedness and conservation of weight based on Piaget's theory of intelligence. A total of 56 gifted and 72 nongifted children (ages 114-150 months) were tested on a series of tasks designed to measure conservation of weight. (MS)

All of the children were presented conservation of liquid and weight problems and 12 metaphor items. The results suggest that hearing loss did not affect the solution of either conservation or metaphor. (Author)

Compared the performance of 29 institutionalized cultural-familial mental retardates on Piagetian conservation tasks. Examined the effects of age, sex, and degree of retardation on conservation performance. (BD)

The relation of CA, MA, and IQ to conservation was examined by comparing the performance of bright, normal, and retarded children matched on the critical MA of six years. (Author)

Results indicate that within the limitations of this study there is evidence that children with superior" intelligence showed more mature response patterns on Piaget-type tasks than children of the same age with average" intelligence test scores. (Author)

This paper reviews studies in which scores on Piagetian tests of logical thought were correlated with IQ, mental age (MA) and chronological age (CA), and examines the possible effects of the size of the age range and mean age of subjects on these correlations. The data included 44 groups of subjects obtained from 36 studies in which Piagetian and…
