Situations of language contact are often the norm for sign languages. This article investigates a case of unimodal contact between Cena, a young sign language in its third generation that is used in a small rural community in Brazil, and Libras, the national sign language of Brazil. Our analysis concerns one by-product of this contact: reiterative…

Due to the typological differences between Korean's aspect system and English's aspect system in terms of progressive construction "-ko iss," learners can no doubt have difficulty acquiring and using the "-ko iss" construction in learner Korean. This dissertation investigates two main points: (i) how is the "-ko iss"…

Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

In this paper, I provide an analysis of 'verbless' sentences in Arabic (mainly, the Standard variety, SA) in light of the claims of the feature-based probe-goal-Agree system of Chomsky (2001, 2004) and such assumptions as held by Biberauer et al. (2010) about probe-goal Agree relations being parameterized according to the feature-structure of…

English ditransitive verbs show a complex alternation between the double object construction (DOC, (1)) and prepositional object datives (POD, (2)). This dissertation examines the acquisition, representation, and learnability of the dative alternation among L2 English learners, presenting experimental data from participants with L1 backgrounds of…

When learning a language, typically-developing infants face the daunting task of learning both the sounds and the meanings of words. In this dissertation, we focus on a source of variability that complicates the one-to-one relationship between words and their meanings: wordform variability. In Chapter 1 we make a distinction between the micro…

This study emerged as a result of insufficient knowledge and descriptions of the behavioural profiles of the near-synonym English verbs, "increase" and "rise," by non-corpus-based traditional reference sources used by students. We explored the behavioural characteristics of this group of near-synonym verbs using the British…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

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 present study examines the tradeoff between the on-line construction of modifier-noun gender agreement and verb-subject person/number agreement vs. the automatization and entrenchment of agreement, through the study of bilingual speakers of Spanish and the Afro-Colombian creole language Palenquero, whose lexicon is highly cognate with Spanish,…

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 Interface Hypothesis proposes that the pragmatic-discursive interface with syntax is more vulnerable to crosslinguistic influence than the syntactic-semantic interface [Tsimpli, Ianthi, and Antonella Sorace. 2006. "Differentiating Interfaces: L2 Performance in Syntax- Semantics and Syntax-Discourse Phenomena." In Proceedings of the…

Mixed languages like Media Lengua incorporate grammar from one source language (here, Quichua) but lexicon from another (here, Spanish). Due to their linguistic profile, they provide a unique window into bilingual language usage and language representation. Drawing on sociolinguistic, structural and psycholinguistic perspectives, the current…

Constraints on linguistic variation are consistent across adult speakers, yielding probabilistic and systematic patterns. Yet, little is known about the development of such patterns during childhood. This study investigates Spanish subject pronoun expression in naturalistic data from 154 monolingual children in Mexico, divided into four age…

This paper investigates the syntactic dependency between complementisers and verbal forms in Standard Arabic and provides a new analysis of this dependency. The imperfective verb in this language surfaces with three different forms, where each form is indicated by a different suffixal marker attached to the end of the verb as (-u), (-a), or (-Ø).…
