The aim of this study was to examine how native speakers (L1) of Turkish, a morphologically rich language, process a second language (L2) which is morphologically less productive such as English. Critically, the study examined morphological priming effects together with a transposed-letter (TL) methodology using the same target word and compared the processing of derived word forms in L1 English speakers to that of L1 Turkish speakers of L2 English. Two masked primed lexical decision experiments were conducted in which the same target (e.g., BRAVE) was preceded by a morphological prime (braveness), a TL-within prime (braevness), an SL-within prime (braocness), a TL-across prime (bravneess), an SL-across prime (bravruess) or an Unrelated prime (directness). Furthermore, to clarify the conflicting empirical evidence in L1 and L2 morphological processing, the potential impact of individual differences in the reading networks of individuals was explored. The average group data yielded robust morphological priming in both L1 and L2 speakers, while significant TL priming for within-morpheme transpositions was obtained only in L1 speakers. Nevertheless, the findings of exploratory analyses into the potential effects of individual variability suggested individual differences might indeed moderate the size and the magnitude of group-level priming in L1 and L2 speakers, leading to the emergence of TL priming effects for particular groups in L2 speakers. These results provided some resolution to the earlier inconsistent empirical evidence, highlighting the importance of considering individual differences while testing L1 and L2 populations.

The L2 production of English comparative structures More support for L2 developmental changes Kırkıcı, Bilal (2012-01-01) This study presents the results of an elicited production task on English comparative adjectives conducted with L1 Turkish learners of L2 English. The obtained results indicated processing differences both between the L2 participants and the L1 controls and between the higher and lower proficiency L2 participants. It is claimed that these results provide further support for the view that L2 learners tend to rely more on lexical storage and less on computational processes in the processing of morphologically...
Intercultural Sensitivity of EFL Learners at a State University Gedik Bal, Nur (2020-06-01) The purpose of this explanatory sequential mixed method study was to identify the level of English as a foreign language (EFL) learners’ intercultural sensitivity (IS) and reveal underlying factors that might have impact on learners’ IS. Participants were 113 EFL learners studying in the preparatory school of a state university. IS scale created by Chen and Starosta (2000) was implemented. Interviews were also conducted with nine volunteer students. Quantitative data were analyzed via SPSS whereas qualitat...
Syntactic priming of relative clause attachment in monolingual Turkish speakers and Turkish learners of English Başer, Zeynep; Hohenberger, Annette Edeltraud; Zeyrek Bozşahin, Deniz; Department of Cognitive Sciences (2018) The purpose of this study is to investigate the syntactic priming of relative clause attachment in monolingual Turkish speakers and Turkish learners of English with different levels of proficiency in English. Turkish and English belong to typologically different groups of languages. Within the scope of this study, we investigate syntactic priming of relative clause attachments, which enables us to examine and compare the strategies employed for ambiguity resolution both in Turkish and English. The data was ...
An investigation of the citation transformation types in MA and PhD theses Dogan, Fatma Seyma; YAĞIZ, Oktay; Kaçar, Işıl Günseli (2018-11-03) This study investigates the types of citation transformation preferred by both English L1 (native language) writers and Turkish writers who use English as a foreign language (L2). The corpus consists of 34 theses, 17 of which are Turkish writers' theses in English language including 10M.A. and 7 PhD theses and 17 English L1 writers' theses comprised of 10M.A. and 7 PhD theses. Based on the relevant literature, a rubric was prepared by the researchers in order to analyse the theses by means of qualitative co...
Investigations of the mind and brain: assessing behavioral and neural priming in L2 morphology Demir, Orhan; Kırkıcı, Bilal; Department of English Language Teaching (2020-10-15) The main goal of this thesis was to investigate the temporal and spatial properties of early morphological processing in a second language (L2). For this purpose, a computer-based masked-priming lexical decision task was implemented, which was followed by a functional magnetic resonance imaging (fMRI) experiment with minimal differences in the data collection procedure. The first experiment was completed by 122 L2 learners of English (L1: Turkish) and the participants of the fMRI study were a subgroup...
