Previous research has shown that linguistic cues such as mental and modal verbs can influence young children's judgments about the reliability of informants. Further, certain languages include grammatical morphemes (i.e. evidential markers), which clarify the source of information coming from testimony (e.g., Bulgarian, Japanese, Turkish).…

Aspectual and mood morphology are vulnerable domains in adult heritage speakers. This paper investigates the root of such vulnerability within the domain of Turkish evidentiality system by comparing 20 second-generation adult and 20 school-age child Turkish heritage speakers to 20 first-generation immigrants (main input providers for child…

Previous work has shown that heritage grammars are often simplified compared to their monolingual counterparts, especially in domains in which the societally-dominant language makes fewer distinctions than the heritage language. We investigated whether linguistic simplification extended to the anaphoric system of Turkish heritage speakers living…

In this study, verb placement with respect to negation is investigated in elicited production and elicited sentence imitation data collected with child second language (L2) learners of German. These data are compared to published data from adult L2 learners, which were collected with the same elicitation materials and were re-analysed for the…

Determining how and why adult outcomes of heritage speaker (HS) bilingualism differ from monolinguals is difficult because it requires the reconstruction of developmental paths from end-state data. In an effort to address this issue, we examine HSs of Turkish in Germany at an early age of development (10-15 years old, n = 22), as well as…

This study investigates the effects of early second-language (L2) acquisition on introduction of characters in narrative discourse by comparing 5- and 7-year-old monolingual (first-language [L1] = Turkish) and bilingual (L1 = Turkish, L2 = English) children. Turkish does not have a grammaticalized article system like English which enables to…

How languages are acquired and what stages learners go through has been the focus in language teaching area, and this cross-sectional study investigated the use of English adverbs by elementary, pre-intermediate and intermediate level Turkish EFL students at Anadolu University School of Foreign Languages by analyzing it from acquisitional…

The present study is a follow-up study of Çakir (2016b) which focused on the wh-adverbial & which NP constructions asymmetry within island structures in Turkish. The characteristics of wh-adverbial nasil "how" is compared with the which-NP constructions "hangisekilde" "in what way" and "hangihalde"…

To what extent can second language (L2) speakers acquire a syntactic representation for an L2 structure absent in the first language (L1)? Findings from L2 structural priming studies are in conflict inasmuch as evidence for and against continuity between L1 and L2 sentence production has been shown. Furthermore, previous investigations have not…

A significant body of theoretically motivated research has addressed the role of Universal Grammar (UG) in the nonnative acquisition of morphosyntax and properties of the syntax-semantics interface, but very little research has addressed the role of phonological principles of UG in nonnative language acquisition. Turkish has a regular and…

Is there an ideal time window for language acquisition after which nativelike representation and processing are unattainable? Although this question has been heavily debated, no consensus has been reached. Here, we present evidence for a sensitive period in language development and show that it is specific to grammar. We conducted a masked priming…

The debate whether the second language or foreign language learners' mother tongue should be included in L2 settings is among the crucial issues of second language acquisition and language teacher training (Atkinson, 1987; Brooks-Lewis, 2009). Moving with this debate, this study focuses on the uses and functions of Turkish in the collaborative…

This article presents the results of experimental data on language production and comprehension. These show that adult learners of Dutch as an additional language, with different language backgrounds, and a L2 proficiency below level A2 (Waystage) of the Common European Framework of Reference for Languages (CEFR; Council of Europe, 2001), use…

The purpose of this article is twofold: to describe a prototype for a computer-assisted task-based language instruction (CATBI) tool designed and developed for Turkish as a Foreign Language, and to report on the effectiveness of the CATBI tool. More specifically, this work discusses an experimental study that examined the role of teaching approach…

Odlin (2003) observes that there is no consensus among researchers regarding the importance of L1 transfer in second-language acquisition (henceforth SLA). To test whether L1 transfer is a significant factor in SLA of English relative clauses (RCs), an English-language acceptability judgment task (AJT) with a four-point rating scale was…
