Many children learn language, in part, from the speech of non-native speakers who vary in their language proficiency. To investigate the influence of speaker proficiency on the quality of child-directed speech, 29 mothers who were native English speakers and 31 mothers who were native speakers of Spanish and who reported speaking English to their…

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…

A large amount of literature exists on how native speakers derive and process pragmatic inferences, yet few studies have examined the issue in second language learners, despite a controversial debate of second language (L2) ultimate attainment of phenomena situated at external interfaces. This study contributes to the debate on the integration of…

There is a change in the status of English from a foreign language to a common language of communication among people with different mother languages. While the new profile of English as a lingua franca (ELF) has important implications for language teaching, it is not yet clear how far language teachers in different learning contexts have embraced…

Previous research has shown that English regular past-tense forms are difficult to perceive, yet perception studies to date have used experimentally manipulated input, and none has investigated how contextual cues, beyond temporal adverbials, affect the perception of the regular past. This study investigated whether second language (L2) learners…

The current study contributes to the argument regarding whether L2 learners up to advanced levels make agreement errors on grammatical gender. It reports gender agreement accuracy on a written Grammaticality Judgment Task (GJT) and an Elicited Oral Production Task (PDT) on known nouns assigned the correct gender by participants on a vocabulary…

This study focuses on L2 French spoken in two different Laurentian settings in Canada: L2 French spoken by anglophones who have developed bilingual community practices in Montreal, where French is the majority language; and L2 French spoken by anglophones who have learned French in a formal context in Ontario, where French is a minority language.…

The factors that influence rater scoring have been a subject of great interest to researchers in second language assessment. However, the research on the impact of test-takers' speech profiles (e.g., a jagged or a flat profile reflecting analytic subscores) on raters' scoring behaviors remains to be seen. To investigate the role of speech profiles…

Visual input enhancement (VIE) increases the salience of grammatical forms, potentially facilitating acquisition through attention mechanisms. Native English speakers were exposed to an artificial language containing four linguistic cues (verb agreement, case marking, animacy, word order), with morphological cues either unmarked, marked in the…

One of the most compelling pieces of evidence for the presence of predictions in language comprehension comes from event-related potential (ERP) studies which show that encountering an adjective whose gender marking is inconsistent with that of a highly expectable noun leads to an effect at the adjective. Until now the mechanism underlying this…

This study tests the Competing Systems Hypothesis (CSH) as applied to adult second language acquisition of aspect in Spanish. The CSH purports that differences among tutored and untutored learners result from competition between one system of underlying grammatical knowledge and another of learned metalinguistic knowledge in tutored learners…

We study how people attend to and memorize endings of events that differ in the degree to which objects in them are affected by an action: "Resultative" events show objects that undergo a visually salient change in state during the course of the event (peeling a potato), and "non-resultative" events involve objects that undergo…

In teaching Turkish language as a foreign language, the purpose is to enable the target audience, who have diverse purposes for learning the language, coming from a variety of cultures and languages, to reach such a level that they could understand whatever they listen and read and they could express their feelings, thoughts and dreams verbally as…

This study investigated classroom interaction through the framework of "stancetaking" (Du Bois, 2007) to understand how Spanish second language (L2) learners positioned themselves when participating in communicative language learning activities. Data came from transcribed audio and video recordings of three 90-minute lessons in one…

Recognizing the importance of multinational telecollaboration and form-focused instruction in computer-assisted language learning teacher education, this article investigates teaching English grammar through a seven-week-long telecollaborative project with 41 pre-service language teachers from the United States (US), Poland, and China. The…
