This mixed methods study draws upon theoretical perspectives from usage-based linguistics (UBL) and variationist sociolinguistics to explore four learners' use of second language (L2) Spanish present tense indicative verbal inflectional morphology (i.e., simple present conjugations). The study compares the frequency and distribution of students'…

This study is a replication and extension of Morgan-Short et al.'s (2018) investigation into the role of attention in input processing by L1-Polish learners of L2-Spanish, with proficiency and language of assessment explored as two key methodological factors. Our aims were twofold: to investigate learners' comprehension in different conditions…

The interactionist hypothesis holds that conversational interaction facilitates second language (L2) learning by providing learners opportunities to receive meaningful input, modify their output, and attend to language form. Although research has often explored the efficacy of different types of L2 instruction (deductive or inductive), few studies…

This study builds on prior research on second language (L2) Spanish psych verbs, which has centered on morphosyntactic properties, by examining their syntactic distribution, which relies on lexical semantic knowledge. The fact that certain forms are licensed for some verbs, but not others, is the result of an underlying lexical semantic difference…

This thesis examines whether native, heritage, and L2 speakers of Spanish engage a morphological layer of representation in the processing of inflected words, and whether they do so with both regularly- and irregularly-inflected words. Also examined is whether this tendency towards compositional (i.e. morphological rule-based) processing is…

The acquisition of verbal morphology presents challenges for many second language (L2) learners, in part because they do not readily process those forms during sentence comprehension. Instead, L2 learners rely on lexical-semantic cues (e.g., temporal adverbs and explicit subjects). This study investigated the role of task-essential training in…

Evidence for the role of corrective input as a facilitator of language acquisition is inconclusive. Studies show links between corrective input and grammatical use of some, but not other, language structures. The present study examined relationships between corrective parental input and children's errors in the acquisition of the Spanish copula…

This dissertation offers new approaches to an old and well-known problem in the study of the development of Romance varieties: duplicate lexis or doublets. Traditional analyses of duplication are narrow in scope both in what qualifies as a doublet (the popular/learned opposition has dominated, to the exclusion of other pairs) and in channels of…

Seeing the logical problem of second language acquisition as that of primarily selecting and re-assembling bundles of features anew, Lardiere proposes to dispense with the deductive learning approach and its broad range of consequences subsumed under the concept of parameters. While we agree that feature assembly captures more precisely the…

This article studies the acquisition of copulas by a Spanish-English bilingual between the ages of 1;6 and 3;0, examines the possibility of interlanguage influence, and considers the distributional frequencies of copular constructions in the speech of the child and in the language input from adults. The study is of interest because the bilingual…

Purpose: This study assesses the factors that contribute to Spanish and English language development in bilingual children. Method: Seven hundred and fifty-seven Hispanic prekindergarten and kindergarten-age children completed screening tests of semantic and morphosyntactic development in Spanish and English. Parents provided information about…

This study compares the linguistic knowledge of adult second language (L2) learners, who learned the L2 after puberty, with the potentially "eroded" first language (L1) grammars of adult early bilinguals who were exposed to the target language since birth and learned the other language simultaneously, or early in childhood (before age 5). I make…
