Abstract
Previous studies have shown that exposure to a second language (L2) changes one’s perception and production of L2 sounds to become more native-like (e.g., Flege, 1995; Flege & MacKay, 2004). This change has been documented most commonly among immigrants after they move to an environment where the L2 is the main means of communication (e.g., Jia & Aaronson, 2003). However, many people get introduced to a foreign language in school and it has been found that the amount of L2 exposure provided to students in a foreign language classroom is not equivalent to the amount of exposure experienced by immigrants and, therefore, will not produce the same kinds of benefits (e.g., White & Genesee, 1996). This dissertation aimed to examine the effects different amounts of L2 exposure in a classroom environment can have on the perception and production of English front vowels (/i ɪ e ɛ æ/). The participants for this study were a group 2nd, 4th, and 6th graders from two schools (one bilingual, one non-bilingual) who shared the same L1 (Spanish) and age of first exposure to L2 English, but who differed in the amount of L2 exposure they received each week (5 hours vs. 14 hours). The participants’ perception was examined through a categorical discrimination task and their production of English front vowels was elicited via a picture-naming task. Predictions surrounding the relative discrimination difficulty of certain vowel pairs were made through the Perceptual Assimilation Model for Language Learners (PAM-L2) (Best & Tyler, 2007) and their production was evaluated through the Speech Learning Model (SLM) (Flege, 1995). Results from the perception task found a significant effect for school - the additional L2 exposure provided to the bilingual school students beneficially impacted their overall performance on the categorical discrimination task. However, this advantage was not clearly exhibited in their production because participants from each school were able to produce each English front vowel in a significantly distinct way. Further research will have to be conducted to see if the differences in production between the two schools affected the intelligibility of the target words.
