Acquisition of the perfective marker "-le" in Mandarin Chinese is a daunting task for second language learners. To date, there has been no consensus on what it is about "-le" that makes it such a challenge to learners. This study investigates the acquisition of "-le" from both a lexical perspective and a discourse…

This dissertation interrogates the representation of syntactic locality constraints, specifically intervention locality, within child grammar. Our focal point is the Intervention Hypothesis, which suggests that children are governed by a strict version of featural Relativized Minimality, leading to comprehension difficulties when partial featural…

One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

This dissertation investigates how parametric variation of linguistic properties leads to similarities and differences in language processing across the levels of words, grammatical features, and sentences. For a truly generalizable theory of psycholinguistics, the languages surveyed should not be constrained to English (Garnham, 1994; Norcliffe…

The objective of this dissertation is to test some major theories on the discourse function of the Greek indicative verb-forms in narrative. Since the publication of Stanley Porter and Buist Fanning's doctoral dissertations, verbal aspect has been a major area of research among scholars. Although the debate and research concerning the aspect of…

The relationship between language and thought has fascinated us for centuries. The relationship between the two is far beyond what the two words represent on the literal level, and the discussions around it have been covered in various fields from philosophy and psychology to linguistics. Even complicating the situation, the relationship between…

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…

Conceptual Metaphor (CM; e.g., Lakoff & Johnson, 1980, 1999; Kovecses, 2020) is central to our thinking and ubiquitously manifested in our language. Given its importance, the teaching of conceptual metaphors has gained much attention in Cognitive Linguistics and Applied Linguistics. While most empirical studies have focused on specific aspects…

The second language (L2) acquisition of tense, aspect, and mood/modality (TAM) has been widely explored as it holds the promise of a better understanding of the L2 learners' linguistic competences, particularly semantically and morpho-syntactically. This study focuses on the acquisition of the subjunctive mood by L1 English learners of L2 French…

That there exists a group of biblical Hebrew verbs which appear in both transitive and intransitive grammatical constructions has long been recognized. However, explanations of this phenomenon among modern BH grammarians, especially regarding the grammatical status of the Object, have been unsatisfactorily vague. Many issues relevant to the BH…

In this dissertation, I investigate specificational copular clauses (Higgins 1973). My aim is to not only propose an analysis for how such specificational copular clauses are derived but also to use such constructions as a testing ground for evaluating and/ or revising different aspects of linguistic theory. The language I primarily use towards…

One of the most researched challenges in learning Spanish is the acquisition and use of the past aspect, namely, the preterit and imperfect. L2 learners encounter this challenge due to differences in how native English and Spanish speakers view past events. Numerous studies on the Spanish past aspect have analyzed L2 learners' past aspectual…

A class of Modern Standard Arabic complementizers known as "'?inna' and its sisters" demonstrate unique case and word order restrictions. While CPs in Arabic allow both Subject-Verb (SV) and Verb-Subject (VS) word order and their subjects show nominative morphology, CPs introduced by "?inna" ban a verb from directly following…

The current project investigates developmental aspects of acquiring locative verb constructions in English as a second language. Locative verbs, such as "to pour," "to spill," "to spray," and "to sprinkle," constitute a prototypical case of an overgeneralization problem in language learning: Whereas some of…

This dissertation focuses on when and how children learn about the meanings of the propositional attitude" verbs know" and "think". "Know" and "think" both express belief. But they differ in their veridicality: "think" is non-veridical and can report a false belief; but "know" can only…
