Polysemy and memory

The degree of ambiguity of words with multiple meanings was estimated by the semantic uncertainty (U) of a word as measured by word association and sentence generation tasks. Ambiguous words defined in this way were as well remembered in a recognition memory test as control words. When words were first presented in sentences that would determine their encoded sense, it was found that successive encodings of an ambiguous word converged more when the word appeared in its primary sense than when it appeared in its secondary sense. However, given convergent encodings, recognition was more likely if the word had first occurred in its secondary sense. An explanation in terms of semantic focus is offered and related to the general relationship between recognition and frequency.The research reported in this paper was supported by the Learning Research and Development Center, which is supported in part by the U.S. Office of Education.

Polysemy and the acquisition of the cognitive internal state lexicon

Previous research (Hall, Scholnick, & Hughes, 1987) suggested that cognitive word meanings denote six increasingly abstract and complex cognitive processes. In this paper, we further investigated two interrelated aspects of this framework. A set of 36 conversations with children aged 4:5 to 5 provided the data. In Study 1, issues related to the optimal ordering of levels were examined by comparing the original sequence with a restructured model. In Study 2, the hypothesis that, in addition toknow, other polysemous cognitive internal state words would be hierarchically organized was tested. The findings lent support to the restructured model, but rejected the hypothesis that polysemous words within the domain were characterized by equivalent,hhierarchically organized levels. We conclude by proposing that cognitive internal state words were related by complementarity of levels rather than equivalence.The research on which this paper is based was supported by a grant from the Carnegie Corporation of New York to William S.
