Usage-based theory has proposed that learning of linguistic constructions is facilitated by input that contains few high-frequency exemplars, in what is known as a skewed (or Zipfian) input distribution. Early empirical work provided support to this idea, but subsequent L2 research has provided mixed findings. However, previous approaches have not…

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 article provides a Poverty of Stimulus argument for the participation of a dedicated linguistic module in second language acquisition. We study the second language (L2) acquisition of a subset of English infinitive complements that exhibit the following properties: (a) they present an intricate web of grammatical constraints while (b) they…

Children with developmental language disorder (DLD) have significant deficits in language ability that cannot be attributed to neurological damage, hearing impairment, or intellectual disability. The symptoms displayed by children with DLD differ across languages. In English, DLD is often marked by severe difficulties acquiring verb inflection.…

This work investigates the acquisition of Spanish dative alternation (DA) in the production of English-Spanish bilingual and Spanish monolingual children. We explore whether "a/para"-datives and dative clitic doubled (DCLD) structures are syntactically derived from one another or, whether they are different structures. We also examine…

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…

The Spanish subjunctive mood (SUBJ) is said to be highly vulnerable in heritage language (HL) acquisition. However, there is little controlled research on HL-speaking children acquiring the various Spanish SUBJ contexts, so we do not have a clear picture of when, how, or why heritage speakers (HSs) develop in the SUBJ as they do. This study tests…

The present study explores subjunctive recognition and production among low-proficiency learners in the written and aural modalities. It seeks to establish whether mood recognition and production are increased due to irregular morphology and/or input manipulation. A total of 97 participants enrolled in second-semester Spanish classes completed…

Previous research has demonstrated the effectiveness of captioning in second language (L2) comprehension and vocabulary learning. However, little attention has been paid to its potential in supporting grammar development, another challenging area in L2 acquisition. In this research, we used a randomised control design to investigate the role of…

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…

Cross-linguistically, monolingual children produce target-like inflected verbs much earlier than they can reliably distinguish between singular and plural subject-verb agreement morphology in comprehension (i.e. Johnson, V., J. de Villiers, and H. Seymour. 2005. "Agreement Without Understanding? The Case of Third Person Singular /s/."…

This study compares Spanish instructors' use of preterite and imperfect in the foreign language classroom to the distribution of these forms in large-scale corpora, which represent the input learners would potentially receive in a naturalistic learning context. Twenty-four 50-minute class sessions were recorded, and all tokens of preterite and…

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…

This dissertation investigates the knowledge of English non-finite complement constructions by near-native L1 Spanish/L2 English learners. In particular, this study concerns Object Control, Raising to Object, and "for"-type constructions. Although the three constructions look identical on the surface, they are in fact distinct syntactic…

In seeking to both confirm previous conclusions and expand the literature of the field with a different group of participants, McNulty (2012) was (partially) replicated. Three instructional interventions were designed to ascertain which activity type was responsible for learner gains. One treatment group (R) included referential-only practice…
