The psychological reality of word senses

This paper tests psychologists' frequent assumption that dictionaries are psychologically realistic models of polysemy in the mental lexicon. Psychologists have not often explored the nature of polysemy, and lexicographers' methods have not involved scientific sampling of usages or informants. It is argued, however, that the lexicographic technique of citation sorting is an effective way of discovering sense differences. Here this technique was used in three tasks involving usage samples for 24 high- and low-frequency nouns varying widely in degree of polysemy in the dictionary. Analyses of agreement within and between subjects showed that subjects consistently judged and substantially agreed upon the major senses of most nouns, but that few nouns in either frequency group were perceived to have more than three significant senses. Additionally, the possibility that larger usage samples will bias people to make more sense groupings was found not to be true, suggesting that the larger number of senses lexicographers create for high-frequency words are not artifacts of larger usage samples.This research was partially supported by grants from the Spencer and Sloan Foundations to George A.
