Dialects vary in their allophonic patterns, which can affect listeners' phonological and lexical representations. I explore how different exposure to dialect-specific allophonic patterns for two vowels in American English, /ae ai/, affects listeners' lexical processing behaviors across three perception tasks: perceptual similarity, priming, and…

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…

The present paper addresses the study of non-arbitrariness in language within a deep learning framework. We present a set of experiments aimed at assessing the pervasiveness of different forms of non-arbitrary phonological patterns across a set of typologically distant languages. Different sequence-processing neural networks are trained in a set…

The present study examines the production and intuition of Spanish clitics in clitic left dislocation (CLLD) structures among 26 Spanish heritage speakers (HSs) born and raised in Brazil. We tested clitic production and intuition in contexts in which Spanish clitics vary as a function of the semantic features of the object that they refer to.…

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…

Does language development drive language change? A common account of language change attributes the regularity of certain patterns to children's learning biases. The present study examines these predictions for change-in-progress in the use of "must" in Toronto English. Historically, modal verbs like "must" start with root…

This study aims to explore how corpus-based approaches can be used to address the distinctions of English near-synonyms effectively. Especially, it collected source data from the British National Corpus (BNC) and adopted Sketch Engine (SkE) as an analyzing tool to compare the near synonymous pair "damage" and "destroy" commonly…

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…

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…

Purpose: This article aims to describe how exemplar variability can manipulate the word learning environment to maximize within- and cross-language generalization in Spanish--English bilinguals. Furthermore, we examined sources of individual variability that predicted word learning. Method: Nineteen Spanish--English bilingual children participated…

Research on multilingual acquisition has investigated various combinations of languages to identify the factors determining how learners express motion. Our research examines the semantics of motion expression in learners whose first language (L1) exhibits more variation than their foreign language (L2/L3). The present study compares upward motion…

This dissertation examines Spanish Direct Object clitic pronouns in Argentine spoken Spanish of adults and children (ages 4;0-7;0). It concentrates on (Finite verb + Nonfinite verb) constructions that allow both pre-verbal (Proclisis) and a postverbal (Enclisis) clitic placement. Previous corpus studies have shown that lexical (finite verb),…

This research was conducted to investigate how frequently Turkish advanced learners of English use the logical connector "thus" in their academic prose and to investigate whether it was overused, underused or misused semantically in comparison to English native speakers. The data were collected from three corpora; Corpus of Contemporary…

This study reports on the results of classroom research investigating the effects of using data-driven learning methods by students in revising their writing errors. The main purpose of the study is to examine to what extent is consulting a corpus effective in correcting lexical errors in their writing. It has been found in previous research that…

Grammatical agreement makes different demands on speakers of different languages. Being widespread in the languages of the world, the features of agreement systems offer valuable tests of how language affects deep-seated domains of human cognition and categorization. Number agreement is one such domain, with intriguing evidence that typological…
