Dw. Gow et Pc. Gordon, LEXICAL AND PRELEXICAL INFLUENCES ON WORD SEGMENTATION - EVIDENCE FROM PRIMING, Journal of experimental psychology. Human perception and performance, 21(2), 1995, pp. 344-359
The authors examined the interaction of acoustic and lexical informati
on in lexical access and segmentation. The cross-modal lexical priming
technique was used to determine which word meanings listeners access
at the offsets of oronyms (e.g., tulips or two lips) presented in conn
ected speech. In Experiment 1, participants showed priming by the mean
ing of tulips when presented with two lips. In Experiment 2, priming b
y the meaning of the 2nd word was found in such sequences (e.g., lips
in two lips). Finally, Experiment 3 demonstrated that listeners do not
show priming by lips when it is pronounced as part of tulips. The res
ults of these experiments show that listeners sometimes access words o
ther than those intended by speakers and may simultaneously access wor
ds associated with several parses of ambiguous sequences. Furthermore,
the results suggest that acoustic marking of word onsets places const
raints on the success of lexical access. To account for these results,
the authors propose a new model of lexical access and segmentation.
