This dissertation investigates a typologically rare linguistic phenomenon found in Irish from three different perspectives: how it challenges phonological theory, how it is used by contemporary speakers, and how its written representation affects its acquisition. Initial consonant mutation (ICM), as it appears in the Celtic languages, is known to…

We examined the role of modality in learning second language (L2) grammar and forming implicit (unconscious) and explicit (conscious) knowledge. To this end, we isolated the effects of the physical medium of input (i.e., aural or visual) from those of the presentation method (i.e., word-by-word or simultaneous). We also explored the role of test…

A collection of cognitive, linguistic, and spelling measures were administered to third-grade English L1 and L2 learners. To capture formative assessments of children's developing mental graphemic representations (MGRs), spelling errors in isolation were subjected to analysis across three metrics: (1) Phonological constrained; (2)…

Through examining all instances of the nontarget "be" before verbs in the written interlanguage of Chinese learners at different proficiency levels, the present study reveals that nontarget "be" performs different functions, and there is a function shift from low to high proficiency levels. At the lowest levels, "be"…

The present longitudinal case study investigated the development of fluency, complexity and accuracy--and the possible relationships between them--in the written production of L2 French. We assessed fluency and complexity in five intermediate learners by means of conventional indicators for written L2 (cf. Wolfe-Quintero et al. 1998), while…

The purpose of this study was two-fold: it primarily intended to incorporate some insights into the newly-explored field of L3A: secondly, it aimed to highlight the significance of translation as a valid language activity in exploring the native language influence on non-native language acquisition process. To this end, it investigated the…
