AbstractIn light of the finding (Bruner et al., 1956) that disjuntive concepts are more difficult for adults than conjunctive concepts, a developmental study of the relative difficulty of conjunctive and disjunctive concepts was carried out. Five groups of children, ranging in age from 5 years to 13 years, were tested on logically equivalent conjunctive and disjunctive concepts. It was found that children of all ages make more errors on disjunctive than conjunctive tasks. The strategies used for conjunctive tasks were more appropriate at all age levels. Because of the fact that the difference in difficulty is quite constant over the age groups, it was concluded that some aspect of conjunctive groupings is more natural. As a result, they occur more frequently and there is greater opportunity to learn to reason correctly about them.
