Disfluency in second language: a study of Turkish speaker of English

Vural, Erkan
The purpose of this study is to investigate disfluency and gesture in the second language under specific conditions such as familiarity vs. non-familiarity, concrete topic type vs. abstract topic type and speaking with native speaker vs. speaker with non-native speaker. The sample of this study was sixteen students from the Department of Basic English in Middle East Technical University (DBE), three instructors from DBE and one instructor from Modern Language Department in Middle East Technical University. Two of the instructors are native and the rest of them are non-native speakers of English. With an assigned instructor each student spoke on the following topics: making spaghetti, giving directions, spring festival and clashing midterms, and effects of religion on our life. The conversations on each topic were recorded audio-visually. Then the audio-visual data was annotated in terms of linguistic and gestural elements. In order to explore the relation among disfluency, gesture and controlled variables, quantitative data analysis methods were used. Levelt’s speech production and Krauss’s gesture production model were used as a basic framework. Dual Coding theory and Metalinguistic Awareness Theory was used to explain intricate results of the present study. As a result of the study, it was found that in the concrete topic condition, learners speak more fluently because of time and topic effects. Similarly, in the condition of familiar addressee and native speaker, learners speak more fluently than they do when speaking with a non-familiar or a non- native speaker.


Intonation structure and intonation in Svo and Ovs sentences in spoken Russian
Ghinda, Elena; Zeyrek Bozşahin, Deniz; Department of Cognitive Sciences (2010)
The purpose of this thesis is to examine the difference between SVO and OVS sentences in spoken Russian, which is a language with flexible word order although the basic order is SVO. Two experiments were conducted to understand the nature of intonation. Experiment 1 shows that the Subject appears as kontrast in OVS sentences, and as background in SVO sentences. The F0 curve rises in the Object position when the Subject is kontrast in OVS sentences. The analysis of the results of Experiment 2 shows that the ...
Connective position, argument order and ınformation structure of discourse connectives in written turkish texts
Demirşahin, Işın; Bozşahin, Hüseyin Cem; Department of Cognitive Sciences (2008)
A text is a linguistic structure that is more than a random collection of sentences. A text is cohesive (Halliday & Hasan, 1976) and coherent (Mann & Thompson, 1987, 1988). Mainly ignored in the field of linguistics until recently, the text and the discourse structure have been inquired from various points of view (Asher, 1993; Asher & Lascarides, 1998; Grosz & Sidner, 1986; Mann & Thompson, 1987, 1988; Webber, 2004). D-LTAG is a discourse grammar work that extends a lexicalized sentence level grammar LTAG ...
Language production in a typological perspective: a corpus study of Turkish slips of the tongue
Erişen, İbrahim Özgür; Hohenberger, Annette Edeltraud; Department of Cognitive Sciences (2010)
The main purpose of this study is to establish a Turkish slips of the tongue (SOT) corpus and make typological comparisons with English, French and German corpora. In the first part of the study, a slips of the tongue corpus has been created. 85 podcast recordings were analyzed and 53 SOT errors were found. SOT errors were extracted from the podcasts and these audio clips were combined with their spectrograms in a flash video. Classification of SOT errors were carried out with respect to linguistic units in...
Computatıonal aspects of discourse annotation
Aktaş, Berfin; Bozşahin, Hüseyin Cem; Department of Cognitive Sciences (2008)
In this thesis, we aim to analyze the computational aspects of discourse annotation. Discourse is not only a concatenation of sentences; in fact the totality of discourse is more than the sum total of the sentences that constitute it. The property that differentiates discourse from a set of arbitrary sentences is defined as coherence. Coherence is established by the relations between the parts of discourse. We have a lexicalized approach to discourse, therefore in this study, discourse relations are conside...
Cognitive development of turkish children on the relation of evidentiality and theory of mind
Özoran, Dinçer; Hohenberger, Annette Edeltraud; Department of Cognitive Sciences (2009)
For the first time a representative Theory of Mind (ToM) scale (Wellman & Liu, 2004) has been cast into three different linguistic forms in order to show the impact of evidential markers on ToM understanding. With Turkish children, we studied (i) a control form without explicit evidential markers, as conducted by Bayramoğlu & Hohenberger (2007), (ii) a verbal form with –DI (marking factuality in the past ) and (iii) a verbal form with –MIS (marking hearsay in the past). To predict ToM performance of childre...
