The representation of polysemous words

Words that have a number of related senses are polysemous. For example, paper refers to both a substance and a publication printed on that substance. Five experiments investigated whether different senses are represented distinctly in the lexicon or if there is a common, core meaning. In all experiments, a polysemous word was used twice, in phrases that selected the same or different senses. Experiment 1 showed that sense consistency aided memory for the polysemous word. Experiment 2 extended this result to a timed sensicality judgment task. Experiment 3 demonstrated that the effects for polysemous words were very similar to those for homonyms. Experiment 4 ruled out the possibility of modifier–modifier priming. Experiment 5 showed that sense consistency facilitates comprehension relative to a neutral baseline, while sense inconsistency inhibits comprehension. These experiments provide evidence that polysemous words have separate representations for each sense and that any core meaning is minimal. © 2001 Academic Press Key Words: polysemy; lexical semantics; psycholinguistics; ambiguity. Much research in lexical representation has compared homonyms with unambiguous words. Homonyms usually arise through a historical accident in which two different word meaning

Paper has been my ruin: conceptual relations of polysemous senses q

Polysemous words have different but related meanings (senses), such as paper meaning a newspaper or writing material. Six experiments examined the similarity of word senses using categorization and inference tasks. The experiments found that subjects did not categorize together phrases that used a polysemous word in different senses, though they did when the word was used in the same sense. Different senses of a word were categorized together no more than 20 % of the time, only slightly more often than different meanings of homonyms. Pre-exposing subjects to a polysemous relation did not increase categorization of word senses that had that relation. Finally, induction from one sense of a word to a different sense was also weak. The results are consistent with the view that polysemous senses are represented separately, often with little semantic overlap, helping to explain previous results that using a word in one sense interferes with using it in another sense, even if the senses are related.
