The aim of this study is to explore the structure of Farsi referring expressions (RE) used during a collaborative Tangram puzzle solving activity, and investigate the role of different visual cue conditions on the types of RE and the degree of gaze coordination. A jigsaw task design was used which required participants to work as a team to solve Tangram puzzles in three conditions where (a) all pieces had the same color (normal condition), (b) all pieces were assigned a distinct color (color condition), and (c) all pieces had the same color but the partner’s gaze information was visualized on the screen (gaze cueing condition). In this respect, two main aspects were under scrutiny: linguistic and dual eye-tacking analysis, while both are assumed to be enriched recourses for modulating joint attention. For this purpose, a corpus of Farsi REs in a situated dialogue environment is constructed to evaluate the frequency of specific RE’s features and their length distribution. Descriptive statistics show that Mosallas (Triangle), Un (That) are the most frequently used RE words in the Farsi corpus. The RE feature distributions are compared with Turkish, Japanese and English RE corpora compiled with the same task to provide a cross-linguistic analysis. Conversational analysis of features of REs revealed the prominent role of color terms in identifying objects and the striking influence of shape and size in gaze cueing condition. Besides, cross-linguistic analysis results demonstrate that Farsi is distant to all languages in this respect. In case of dual eye-tracking analysis, results were not influenced significantly under different status and also along six trials. However, there was a significant interaction effect between conditions and trials especially for the color case.

The Role of modifiers in Turkish discourse bank
Çakmak, Deniz Hande; Zeyrek Bozşahin, Deniz; Department of Cognitive Sciences (2015)
This thesis focuses on the role of modifiers used with discourse connectives and investigates modifiers in terms of affecting the modality of the discourse relations. Modifiers are originally adverbs used for different semantic purposes. The already annotated data in Turkish Discourse Bank, or TDB are used for identifying modifiers and classifying them. In the light of previous studies, the discourse connectives occuring with modifiers are analyzed and classified. The semantic distribution of modifiers is d...
An Experimental investigation of ICT expertise by gaze analysis
Kaya, Erdi; Acartürk, Cengiz; Department of Cognitive Sciences (2019)
The aim of the present study is to contribute to the approaches used for the division of experts and novices according to the approaches and differences in question answering. For this purpose, an experiment was conducted with 41 participants. The subjects were divided into two groups as experts and novices according to their information test scores. Then the participants answered a set of questions based on ICT and their eye movements were recorded. The participants were then divided as high performers and...
An investigation of incidental vocabulary acquisition in relation to learner proficiency level and word frequency
Tekmen, E. Anne Ferrell; Daloğlu, Ayşegül (Wiley, 2006-06-01)
This study examined the relationship between learners' incidental vocabulary acquisition and their level of proficiency, and between acquisition and word frequency in a text. Participants were Turkish learners of English at three proficiency levels. One reading text and four vocabulary tests were administered over a two-week period. Analyses of the data revealed that lexical gains from reading were significant for each group (p < .05). The higher proficiency groups were able to acquire more words than lower...
A Usability Study of WebMaps with Eye Tracking Tool: The Effects of Iconic Representation of Information
Alacam, Özge; Dalci, Mustafa (2009-07-24)
In this study, we aim to conduct usability tests on different WebMap sites with eye movement analysis. Overall task performance, the effects of iconic representation of information, and the efficiency of pop-up usage were evaluated. The eye tracking technology is used for this Study in order to follow the position of the users' eye-gaze. The results show that there are remarkable differences in task performance between WebMaps. Addition, they also differ in the use of iconic representations according to res...
A biophysical network model displaying the role of basal ganglia pathways in action selection
Yucelgen, Cem; Denizdurduran, Berat; Metin, Selin; Elibol, Rahmi; Şengör, Neslihan Serap (2012-10-25)
Basal ganglia circuits are known to have role in a wide range of behaviour spanning from movement initiation to high order cognitive processes as reward related learning. Here, the intention is to have a biophysically realistic model of basal ganglia circuit for voluntary motor action selection. The ultimate aim is to provide a framework for models which could help comprehension of complex processes. To fulfill this aim a model capable of simulating direct, indirect and hyperdirect pathways with modified Ho...
