This dissertation investigates the interplay between the implicit knowledge that learners have of a nonnative language and their processing of that language, examining two types of relative clauses (RCs) in English: gapped RCs (e.g., "the man that they hired") and resumptive RCs (e.g., *"the man that they hired him").…

This dissertation investigates the soft typology of phonological patterns. By studying the types of patterns observed in the world's languages, we can do more than determine what is attested and what is unattested, or what is possible and what is impossible, but discover a wide range of more gradient phenomena. Phonological patterns range from…

In contexts of first language (L1) acquisition, prediction and adaptation are often viewed as fundamental to the learning process (Rabagliati et al., 2016). One mechanism that has been proposed to specifically account for such adaptive behavior is error-based implicit learning (e.g., Chang et al., 2006). According to this account, speakers…

This study investigated the involvement of the Social Agency Theory within a multimedia learning environment to improve English language proficiency. The primary aim of this study is to find the effects of designing language learning instructional videos following the embodiment principle on language learners' motivation, cognitive load and…

Mandarin Chinese verbs are composed of one to four characters that function together as a conceptual unit. However, in modern spoken Chinese, most of these verbs are two-character compounds. This dissertation is focused on adult second language (L2) learners' acquisition of these two-character verb compounds. Specifically, the acquisition of a…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

Recently, there has been considerable L2 research on interfaces between different modules of grammar (internal), such as syntax-semantics, or between grammar and other cognitive systems (external), such as semantics-pragmatics. Sorace's (2011) Interface Hypothesis proposes that L2 learners, even at highly proficient levels, often fail to integrate…

Expectations have been placed upon elementary teachers from the Common Core State Standards in English Language Arts to guide students through close readings of informational and literary texts. This content analysis examined online close reading lesson plans to determine common objectives in elementary close reading lessons using literary text…

Under the framework of item response theory (IRT) and generalizability (G-) theory, this study examined the effects of item difficulty on rating reliability and construct validity on both the constructed-response (CR) items and essay items on English examinations. The data collected for this study were students' scores and responses on the two…

Unlike English, Korean wh-questions do not involve complex syntactic operations of wh-movement and auxiliary inversion; this study explored how this grammatical difference influenced the following two problems. (1) The literature investigating children acquiring wh-movement languages emphasizes relative ease of "subject" wh-questions…

A well-known challenge for language learners is that the input is typically produced by a variety of speakers, each with distinct vocal characteristics (Liberman, Harris, Hoffman, & Griffith, 1957). Accordingly, many studies have indicated that talker variability leads to processing costs for learners across the lifespan (Jusczyk & Pisoni,…

A great deal of research concerning the acquisition of English morphology as a second language has been carried out in order to explain some typical stages in the acquisition of the English-s morphemes and the difficulty confronted by second language learners. According to Siegel (2003), interlanguage and functional transfer both play a crucial…

The purpose of this body of work was to gain a clearer understanding of the potential cognitive factors that may contribute to Specific Language Impairment (SLI). This study attempted to simulate a performance profile of SLI in typically developing children within a grammaticality judgment task, featuring structures historically difficult (third…

The Missionary Training Center (MTC), affiliated with the Church of Jesus Christ of Latter-day Saints, needs a reliable and cost effective way to measure the oral language proficiency of missionaries learning Spanish. The MTC needed to measure incoming missionaries' Spanish language proficiency for training and classroom assignment as well as to…

Learning new vocabulary words in a second language is a challenge for the adult learner, especially when the second language writing system differs from the first language writing system. According to the lexical quality hypothesis (Perfetti & Hart, 2001), there are three constituents to word-level knowledge: orthographic, phonological, and…
