Compositionality has been a central concept in linguistics and philosophy for decades, and it is increasingly prominent in many other areas of cognitive science. Its status, however, remains contentious. Here, I reassess the nature and scope of the principle of compositionality (Partee, 1995) from the perspective of psycholinguistics and cognitive…

This dissertation investigates the wide-ranging implications of a simple fact: language unfolds over time. Whether as cognitive symbols in our minds, or as their physical realization in the world, if linguistic computations are not made over transient and shifting information as it occurs, they cannot be made at all. This dissertation explores the…

This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

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…

To explain the phenomenon that certain English verbs resist passivization (e.g., "*£5 was cost by the book"), Pinker (1989) proposed a semantic constraint on the passive in the adult grammar: The greater the extent to which a verb denotes an action where a patient is affected or acted upon, the greater the extent to which it is…

This study identified and analyzed the common linguistic errors encountered by Linguistics, Literature, and Advertising Arts majors in their Thesis Proposal classes in the First Semester 2016-2017. The data were the drafts of the thesis proposals of the students from the three different programs. A total of 32 manuscripts were analyzed which was…

Language is of vital importance to human beings. It is a means of communication and it has specific cognitive links. Advanced social cognition is necessary for children to acquire language, and sophisticated mind-reading abilities to assume word meanings and communicate pragmatically. Language can be defined as a bi-directional system that permits…

In the syntax literature, it is commonly assumed that a constraint on linguistic competence blocks extraction of "wh-"expressions (e.g. "what" or "which book") from embedded questions, referred to as "wh-"islands. Furthermore, it is assumed that there is an argument/adjunct asymmetry in extraction from "wh-"islands. We report results from two…

The current study tests the Interface Hypothesis through forward and backward anaphora in complex sentences with temporal subordinate clauses in highly proficient English-speaking learners' second-language (L2) Chinese. Forward anaphora is involved when the overt pronoun "ta" "he/she" or a null element appears in the subject…

This article addresses a child language stage that has figured prominently in the current debate on children's early linguistic competence: the Optional Infinitive (OI) stage, a relatively extended period during which children freely alternate between finite and nonfinite structures in contexts where adults only use finite forms. The study…

This study expands upon an existing model of students' reading comprehension ability within an intelligent tutoring system. The current system evaluates students' natural language input using a local student model. We examine the potential to expand this model by assessing the linguistic features of self-explanations aggregated across entire…

One of the intricate properties of second language acquisition is that some types of grammatical feature appear to be acquired easily and in a native-like way, while others remain persistently difficult. There is much evidence related to the issue in the current empirical studies, and the issue raises an important explanatory problem for a theory…

In the 1980s, researchers in child language devised several new experimental techniques to assess children's emerging linguistic competence. Innovations in methodology were needed to bridge the apparent gap between the expectation of rapid language acquisition, based on linguistic theory, and the protracted acquisition that was being witnessed…

This study presents an investigation of oral narratives collected from heritage Egyptian and Palestinian Arabic speakers living in the United States. The focus is on a number of syntactic and morphological features in their production, such as word order, use of null subjects, selection of prepositions, agreement, and possession. The degree of…

A basic challenge for research into the neurobiology of language is understanding how the brain combines words to make complex representations. Linguistic theory divides this task into several computations including syntactic structure building and semantic composition. The close relationship between these computations, however, poses a strong…
