The field of Linguistics has long been interested in the verb meanings of intransitive verbs and their argument structure, specifically the breakdown of intransitive verbs into unaccusative and unergative verb types. Despite extensive research, a universally applicable explanation for this breakdown remains elusive due in part to the variability…

This dissertation investigates when and how children figure out the force of modals, that is, when and how they learn that "can/might" express possibility, whereas must/have to express necessity. Learning modal force raises a logical "Subset Problem": given that necessity entails possibility, what prevents learners from…

This study investigates the acquisition of the Imperfective verb inflection paradigm in Emirati Arabic (EA), to determine whether the learning process is sensitive to the phonological and typological properties of the input. We collected data from 48 participants aged 2;7 to 5;9 years, using an elicited production paradigm. Input frequencies of…

Native speakers of English have a strong preference for transferred negation as opposed to non-transferred negation. The present study aims to examine whether young Chinese-speaking ESL learners have a target-like preference for transferred negation and whether they have a system-wide representation of transferred negation in their early English…

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…

Grammar competition has been proposed as a model for second language (L2) acquisition. Variational Learning provides a framework within which to investigate the idea of grammar competition as the model requires a marriage of quantitative properties of the input with Universal Grammar. A diachronic variational model of grammar competition is…

How strongly a verb is associated with a construction plays a crucial role in the learning of argument structure constructions. We examined the effect of verb-construction association strength on second language (L2) constructional generalization by analysing L2 learners' production and comprehension of two complex constructions (i.e. ditransitive…

Syntactic structures are unobserved theoretical constructs which are useful in explaining a wide range of linguistic and psychological phenomena. Language acquisition studies how such latent structures are acquired by human learners through many hypothesized learning mechanisms and apparatuses, which can be genetically endowed or of general…

This article focuses on the acquisition of mood in early complement clauses of European Portuguese (EP). Two semantic features are involved in the EP mood system--epistemicity and veridicality. An elicited production task administered to 80 children aged 4 to 9 showed that, even though children use the subjunctive in [-- epistemic] contexts, the…

This paper describes a project developed within an ongoing study at the University of Athens. In our previous studies we analyzed the errors of Greek learners of Italian language, using Learner Corpora evidence and we retrieved useful information about their interlanguage and its interaction to the language learning process. In this study we…

This article studies the use of support verb constructions (SVCs) in the written production of learners of Spanish. SVCs are lexical combinations whose content is similar to verbal predicates but is distributed between a verb and a noun, the noun being the carrier of the core lexical meaning of the predicate. Although there is considerable…

This article presents the results of four studies exploring the acquisition of the language-specific syntactic and semantic properties of multiple interrogatives in English, Russian, and Malayalam, languages that behave differently with respect to the syntax and semantics of multiple interrogatives. A corpus analysis investigated the frequency of…

In this article I examine the collocational behaviour of groups of semantically related verbs (e.g., "head, run, manage") and nouns (e.g., "issue, factor, aspect") from the domain of business English. The results of this corpus-based study show that much of the collocational behaviour exhibited by these lexical items can be explained by examining…

Researchers have long debated the mechanisms underlying the learning of syntactic structure. Of significant interest has been the fact that passive constructions appear to be learned earlier in Sesotho than English. This paper provides a comprehensive, quantitative analysis of the passive input Sesotho-speaking children hear, how it differs from…

Advanced learners of second languages and natural language processing systems both demand much more detailed lexical information than conventional dictionaries provide. Text composition, whether by humans or machines, requires a thorough understanding of relationships between words, such as selectional restrictions, case patterns, factives, and…
