This dissertation is about the learnability of different generative, Separationist approaches to nominal morphosyntax. The core of my investigation is number, gender, and declension class, as manifested across nouns, adnominals (adjectives, numerals, demonstratives, and quantifiers), and articles. An extreme position would require that all of…

This study examines the comprehension of verbal passives by children acquiring European Portuguese, in particular with respect to the predictions of the Universal Phase Requirement (UPR) and the Universal Freezing Hypothesis (UFH) regarding children's performance with different types of predicates. Both hypotheses entail the prediction that…

In this article, we propose a reconceptualization of the principles and parameters (P&P) framework. We argue that in lieu of discrete parameter values, a parameter value exists on a gradient plane that encodes a learner's confidence that a particular parametric structure licenses the utterances in the learner's linguistic input. Crucially,…

Previous research suggests that toddlers can rely on distributional cues in the input to track adjacent and nonadjacent grammatical dependencies. It remains unclear whether toddlers understand the hierarchical phrase structures that determine the corresponding grammatical dependencies. We addressed this question by testing toddlers on two…

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…

This study investigated Thai EFL learners' acquisition of English dative constructions, i.e., Prepositional Dative (PD) and Double Object (DO) constructions employing Radford's (2004) Minimalist accounts as a framework and Acceptability Judgment as a task. Two hypotheses were formulated. Firstly, the English PD would be accepted more readily than…

Scope ambiguity arises when a sentence contains scope-bearing logical operators like quantifiers and negation (Fox, 2003). For instance, in English, the sentence 'Every horse didn't jump over the fence' can be interpreted as either 'None of the horses jumped over the fence' (surface scope) or 'Not all of the horses jumped over the fence' (inverse…

The "wanna" facts are a classic Poverty of Stimulus (PoS) problem: "Wanna" is grammatical in certain contexts ("Who do you want PRO to play with?") but not others ("Who do you want who[strikethrough] to play with you?"). On a standard analysis, "contraction" to "wanna" is blocked by some…

How languages are acquired and what stages learners go through has been the focus in language teaching area, and this cross-sectional study investigated the use of English adverbs by elementary, pre-intermediate and intermediate level Turkish EFL students at Anadolu University School of Foreign Languages by analyzing it from acquisitional…

The chapters in this volume, all written by experts in the field, present an array of new research on second language acquisition (SLA) that touches on several current theoretical debates in the field and present a rich range of new empirical data and a number of innovative findings. The studies address questions relating to ultimate attainment,…

This paper investigates the acquisition of syntax in L2 grammars. We tested adult L2 speakers of Spanish (English L1) on the feature specification of T(ense), which is different in English and Spanish in so-called subject-to-subject raising structures. We present experimental results with the verb parecer "to seem/to appear" in different…

L2 learners' problems with English articles have been linked to learners' L1 and their access to universal semantic features (e.g., definiteness and specificity). Studies suggest that L2 adults rely on their L1 knowledge, while child L2 learners rely more on their access to semantic universals. The present study investigates whether child L2…

This study investigates 2-5-year-old Mandarin-speaking children's interpretation of the disjunction word "huozhe" ("or") in two positions in "ruguo" ("if")-conditional statements, i.e., in the antecedent clause versus in the consequent clause. The findings from three experiments show that the meanings…

Past research has emphasized the universality of grammar acquisition over key differences, resulting in the development of a number of one-size-fits-all approaches to grammar instruction. Because such approaches fail to consider disparities of grammatical features, they are often ineffective. Just as a doctor needs to diagnose an illness and…

This study investigated the acquisition of the Spanish clitic se by English native speakers in passive, middle, and impersonal constructions. Little research has been done on this topic in SLA within a UG framework (Bayona, 2005; Bruhn de Garavito, 1999). VanPatten (2004) proposed the Processing Instruction (PI) model arguing for the necessity of…
