Effects of speech practice on fast mapping in monolingual and bilingual speakers.

ABSTRACT

PURPOSE: This study examines the effects of the levels of speech practice on fast mapping in monolingual and bilingual speakers. METHOD: Participants were 30 English-speaking monolingual and 30 Spanish-English bilingual young adults. Each participant was randomly assigned to 1 of 3 practice conditions prior to the fast-mapping task (a) intensive speech practice, (b) moderate speech practice, or (c) no practice. In a fast-mapping experiment, each participant was briefly exposed to novel objects and their corresponding novel words. Participants' knowledge of the target novel words was assessed immediately after the exposures. RESULTS: There were significant effects of speech practice on fast mapping for both monolingual and bilingual adults. It is important to note that participants' language experience also played a role in their fast-mapping performance. CONCLUSION: The findings suggest that speech practice, interacting with language experience, facilitates the processes for fast mapping.
