The first stage of combinatorial speech is better described as variable than uniform. Talk of variants obscures two different aspects of language (knowledge and use) and two different aspects of language development -- acquisition of the grammar (competence) and deployment of the grammar in speaking and listening (performance). Null subjects and…

Miniature language learning has been widely used to study the causality of language universals. However, factors that have been shown to affect language acquisition in other paradigms are understudied in miniature language learning, which calls into question results that claim to uncover universal biases. In this dissertation, I ask how the…

Urdu language is a member of Indo-European family tree and within the zone of Indo-Iranian branch, whereas Turkish language is a member of Altaic family tree. Both of these languages belong to different family trees, but these languages have many words in common. Urdu language has 41 consonant sounds and 11 vowel sounds, whereas Turkish language…

Since the Korean pronoun system does not specify gender indication, Korean speakers of English tend to have difficulties when they use English pronouns. This paper explores how absence of obligatory gender marking in Korean affects gender errors in the production of English. Gender pronoun errors made by Korean learners of English were analyzed…

Distributional learning is typically understood as (unattended) tracking of stimulus probabilities. Distributional training with speech yields mixed results and the influencing factors have not yet been fully investigated. This study explored whether prior linguistic experience could have an effect on distributional learning outcomes. Czech and…

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…

Variability in the form of article (i.e., a and the) omissions and stressing has been attributed to a mismatch between first (L1) and second language (L2) prosodic and syntactic structures. An overlap between the L1 and L2 systems, on the other hand, is expected to contribute to native-like article productions. This case study aims to explore the…

In this dissertation, I investigated how cognitive resources as well as formal, and informal language experience impact language learning in two studies. In the first study (Chapter 2), I examined the learning of Spanish grammatical gender by Chinese international students who were studying abroad in the US. The goal of that study was to uncover…

In bilinguals and second language learners, the native (L1) and nonnative (L2) languages coexist and interact. The L1 influences L2 production via forward transfer, as is seen with foreign accents. However, language transfer is bidirectional: even brief experience with an L2 can affect L1 production, via backward transfer. Here, we review the…

This study investigates prosodic (noun length) and lexical-semantic (animacy) influences on determiner use in the spontaneous speech of three children acquiring French, Austrian German and Dutch. In support of typological and language-specific hypotheses from the Germanic-Romance contrast, an advantage of monosyllabic nouns and of inanimate nouns…

Formality as a style may be defined as language which reflects or "keynotes" the degree of familiarity between participants in a discourse. Working from this assumption, this paper attempts to answer the question, "How is formality best described?" Results of a series of tests indicate that informants' labels (with the…

With a Finnish-speaking majority and a Swedish-speaking minority, Finland offers a striking contrast in the kinds of cross-linguistic influence that can occur in the acquisition of English in a multilingual setting. While much previous research has looked at the differences between Finnish and Swedish influences, our study compares Swedish…
