This dissertation research examines the acquisition of second language vowels. For second language learners, learning a new languages' sound inventory, particularly its vowels, presents a challenge perceptually and in terms of production. Incorrectly perceiving and producing sounds in a second language results in a foreign accent in many adult…

This research project sought to explore the influence of English L2 on Spanish L1 in an environment where the L1 (Spanish) is the dominant language. Participants were recruited through voluntary response sampling at the University of Puerto Rico Secondary School (UHS). They completed a language survey on Google Forms that collected general…

This study examined how language proficiency and age of acquisition affect a bilingual language user's reliance on the dominant language during lexical access. Two bilingual groups performed a translation recognition task: Mandarin-English classroom bilinguals who acquired their dominant language (Mandarin) from birth and their non-dominant…

The current study examines the interplay between global and local processes in bilingual language control. We investigated language-switching performance of unbalanced Arabic-Hebrew bilinguals in cued picture naming, using 5 different cuing parameters. The language cue could precede the picture, follow it, or appear simultaneously with it. Naming…

This article reports on a study investigating the relative influence of the first language and dominant language (L1) on second language (L2) and third language (L3) morpho-lexical processing. A lexical decision task compared the responses to English NV-er compounds (e.g. "taxi driver") and non-compounds provided by a group of native…

This article discusses issues related to oral assessment of school knowledge of L2-educated students. In particular, it examines benefits and disadvantages of students being tested in their L1 (their dominant language) and in their L2 (their language of instruction). The study draws on the data from 37 high school students studying in a content…

First language (L1) attrition research focuses on syntactic and morphological deterioration in environments where L1 "attriters" rarely have contact with their L1, such as immigrants. There is no study that investigates L1 attrition in tones and in contexts where L1 can still be often heard. This study examines this attrition type in…
