Polysemy, the multiple-yet-related senses of a single word form, has been a long-standing problem for linguistic and computational theories of word meaning. A recent class of conceptually-based theories seek to capture the relationship between the multiple senses via structured cognitive links. The links between senses are assumed to be motivated by underlying schema knowledge rooted in internal embodied experience and extended in a nonarbitrary manner via such devices as metonymy and metaphor (Lakoff, 1987). Evidence to date for the motivated nature of sense extensions is descriptive, and the present study tested motivation as a psycholinguistic construct. Experimental evidence was sought in learning tasks looking for sensitivity to relative degree of motivation in on-line learning and processing tasks. Four experiments examined the ability of native-English-speaking subjects to learn and process novel polysemous senses that vary by degree of motivation. In the first experiment the sensitivity of recognition recall and cued recall measures to differences in level of motivation was tested. Using a between-subjects design, motivated sense items were found to be more accurate and easier to recall. In the second and third experiments processing demands were altered to assess the effect of link type when processed test items for meaning. Subjects were required to make a True-False judgment about the trained test items in sentence verification tasks. The results in the second experiment again showed motivated senses processed more accurately and recalled better. In the third experiment the differences between the high and low motivation sets evident in the first two experiments disappeared when antonym paraphrases were compared with the actual paraphrases. In fourth experiment the contribution of L1 English knowledge was assessed by comparing the experimental results with crosslinguistic interpretability ratings. A moderately strong correlation between measures was evident. Overall the results support the non-arbitrary nature of sense extensions consistent with the conceptually-based approach. The research provides one type of evidence needed to establish both the underlying psychological reality of sense motivation and the role of conceptual knowledge in the organization of word meaning.Subjects--Topical Terms:
