Recall of logical and pragmatic implications in sentences with dichotomous and continuous antonyms.

Thirty-six subjects recalled sentences containing dichotomous or continuous antonyms in affirmative or negative form. The subjects made a considerable number of meaning-preserving recall errors for both dichotomous antonyms (not alive recalled asdead) and continuous antonyms (not hot recalled ascold). The negation of a dichotomous antonym logically implies its antonym, whereas the negation of a continuous antonym only pragmatically implies its antonym. Thus, the results suggest that subjects hearing sentences containing a logical or pragmatic implication tend to make the logical or pragmatic inference involved. Then, in recall, they do not remember that this was an inference and make the error of recalling the logical or pragmatic implication in place of the presented sentence.
