Research on language learners' attention suggests that manipulating attention is beneficial in the language learning process as it facilitates the "noticing" of specific linguistic aspects. The current study investigated the effects of directing learners' attention to segments and prosody in English phonetic training. Korean learners of…

Arabic emphasis refers to the production of consonants resulting from a primary constriction in the dental or alveolar region and a secondary constriction in the back of the vocal tract, recognized as 'Emphatic.' These have contrastive consonants produced in the dental or alveolar region, recognized as 'Plain.' The existing research on emphasis in…

This study examined how L2 English speakers interpreted the notion of native English speakers (NESs) and nonnative English speakers (NNESs) and whether nativeness would influence their self-perception and speech production. It aimed at filling the following research gaps. First, limited studies have explored how L2 English speakers view the other…

This dissertation investigates the morphological and morphosyntactic processing of case-marking by native and nonnative speakers of Turkish, through behavioral and electrophysiological responses. The study explores the locus of case processing costs during first (L1) and second language (L2) word recognition both in isolation and in sentences. It…

Naturalistic language learning is contextually grounded. When people learn their first (L1) and often their second (L2) language, they do so in various contexts. In this dissertation I examine the effect of various contexts on language development. Part 1 describes the effects of textual, linguistic context in reading. I employed an eye-tracking…

A fundamental issue in speech science concerns the extent to which speech sounds are mentally represented by articulatory-motor and/or auditory-acoustic features. This dissertation aims to expand upon the current literature by investigating changes in production and perception following visual feedback training with either articulatory or acoustic…

This thesis examines whether native, heritage, and L2 speakers of Spanish engage a morphological layer of representation in the processing of inflected words, and whether they do so with both regularly- and irregularly-inflected words. Also examined is whether this tendency towards compositional (i.e. morphological rule-based) processing is…

This study investigates the multicomponential nature of L2 Arabic writing by adapting a number of direct measures of linguistic "complexity," "accuracy," and "fluency" (CAF) to the measurement of written Arabic texts produced by L2 Arabic learners and Arabic Native Speakers (NSs). Previous studies of L2 writing have…

Native-English speaking adults use morphological decomposition to understand complex words (e.g. "farmer" becomes "farm-er"). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking…

The current study is on second language acquisition (SLA), and the focus is on the process of visual word recognition in English by Arab learners of English as a second language (ESL). Arab ESL learners have poor performance in their visual word recognition in English, which has been explicated in terms of their poor spelling knowledge of English…

Beginning learners of English progress through the same stages to acquire language. However, the length of time each student spends at a particular stage may vary greatly. Under the current educational policies, ELL students are expected to participate in the general education curriculum while developing their proficiency in the English language.…

This work develops a computational methodology new to linguistics that empirically evaluates competing linguistic theories on Spanish verbal mood choice through the use of computational techniques to learn mood and other hidden linguistic features from Spanish belief statements found in corpora. The machine learned probabilistic linguistic models…

The triad dimensions of complexity, accuracy, and fluency (CAF) has been widely used for assessing second language performance and development. Unlike accuracy and fluency, the construct of Chinese syntactic complexity has not been comprehensibly conceptualized or operationalized. Moreover, not tailored to the typological differences such as the…

Second language (L2) learners of tone languages do not perceive and produce the different tones of the target language with equal ease. The most common explanation for these asymmetries is that acoustically salient tones are the easiest to learn. An alternative explanation is that tones are easiest to learn when they are highly frequent in the…

This study examined L2 (German) awareness in intermediate American college learners of German through their judgments of 15 texts that had been authored by either native speakers (NS) or non-native speakers (NNS) or had been created through Web-Based Machine Translation (WBMT). The specific objectives sought to investigate: (a) how learners…
