The meaning of positive polar questions (PPQs) is relatively straightforward, so the truth conditions of PPQs can be decided easily. In contrast, the meaning of negative polar questions (NPQs) may vary, and simple yes-no answers to NPQs have seemingly unpredictable interpretations. For example, a simple yes answer to a PPQ like 'Did you have lunch…

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…

Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

To avoid potential miscommunication resulting from structural ambiguity, speakers and listeners often rely on differences in prosodic realization. For instance, the sentence "Jennifer blackmailed the boss of the clerk [who was dishonest"][subscript RC'] is realized with different prosody depending on the attachment of the relative clause…

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…

The disproportionate representation of English Language Learners (ELL) to special education is widely attributed to the difficulty in identifying a disability through a language in development. This language acquisition or language disorder question has manifested in paradoxical disproportionality patterns for the ELL population. Some…

The purpose of this study was twofold. First, this study was conducted to compare English communicative competency achievement between two different models of instruction. Adult English language learners (AELLs) participated in either the communicative task-based (CTB) or in a more traditional (MT) language instructional approach. The goal of the…

This study introduces a typological model of the "conceptual language-specific approach" to the L2 research on the acquisition of tense-aspect. The model is based on the typological notion of prominence, classifying languages into tense-prominent and aspect-prominent (Bhat 1999) and the L1 research proposal that language-specific…
