Effects of Acoustic Variability on Second Language Vocabulary Learning
Barcroft, Joe; Sommers, Mitchell S.
Studies in Second Language Acquisition, v27 n3 p387-414 Sep 2005
This study examined the effects of acoustic variability on second language vocabulary learning. English native speakers learned new words in Spanish. Exposure frequency to the words was constant. Dependent measures were accuracy and latency of picture-to-Spanish and Spanish-to-English recall. Experiment 1 compared presentation formats of neutral (conversational) voice only, three voice types, and six voice types. No significant differences emerged. Experiment 2 compared presentation formats of one speaker, three speakers, and six speakers. Vocabulary learning was superior in the higher-variability conditions. Experiment 3 partially replicated Experiment 1 while rotating voice types across subjects in moderate and no-variability conditions. Vocabulary learning was superior in the higher variability conditions. These results are consistent with an exemplar-based theory of initial lexical learning and representation.
