Eye movements can provide insight into the cognitive processes behind them. To study group cognition through investigating eye movements, we have developed a software tool (GETapp) to collect eye movement data from groups of participants performing a task on a set of computers in the scope of the Group Eye Tracking (GET) paradigm. Like many real-world systems, the data from group eye tracking experiments are non-linear. We have developed a software tool, a package for the R programming language, called the generalRQA package for analyzing these non-linear data. The methods used in this package are based on recurrences of time-series and implement a part of the theory of Recurrence Quantification Analysis (RQA). In this thesis we describe both the software tools and apply them to propose measures that differentiate between different group formation patterns in a group eye tracking search task.

Eye tracking in multimodal comprehension of graphs Acartürk, Cengiz (2012-07-31) Eye tracking methodology has been a major empirical research approach for the study of online comprehension processes in reading and scene viewing. The use of eye tracking methodology for the study of diagrammatic representations, however, has been relatively limited so far. The investigation of specific types of diagrammatic representations, such as statistical graphs is even scarce. In this study, we propose eye tracking as an empirical research approach for a systematic analysis of multimodal comprehensi...
Secondary-Task Effects on Learning With Multimedia: An Investigation Through Eye-Movement Analysis Acartürk, Cengiz (2017-01-01) This study investigates secondary-task interference on eye movements through learning with multimedia. We focus on the relationship between the influence of the secondary task on the eye movements of learners, and the learning outcomes as measured by retention, matching, and transfer. Half of the participants performed a spatial tapping task while studying the instructional materials, whereas the other half studied the materials, without spatial tapping. The results revealed suboptimal learning outcomes und...
Short-term consolidation of information for episodic memory Özçelik, Erol; Tekman, Hasan Gürkan; Department of Cognitive Sciences (2008) Several lines of evidence from rapid serial visual presentation, attentional blink, and dual-task interference phenomena propose that human beings have a significant limitation on the short-term consolidation process. Short-term consolidation is transferring early representations to more durable forms of memory. Although previous research has shown that masks presented after targets interrupt the consolidation process of information, there is not enough evidence for the role of attention in consolidation fo...
Object detection through search with a foveated visual system Akbaş, Emre (2017-10-01) Humans and many other species sense visual information with varying spatial resolution across the visual field (foveated vision) and deploy eye movements to actively sample regions of interests in scenes. The advantage of such varying resolution architecture is a reduced computational, hence metabolic cost. But what are the performance costs of such processing strategy relative to a scheme that processes the visual field at high spatial resolution? Here we first focus on visual search and combine object det...
Modeling consciousness: a comparison of computational models Gök, Selvi Elif; Sayan, Erdinç; Department of Cognitive Sciences (2009) There has been a recent flurry of activity in consciousness research. Although an operational definition of consciousness has not yet been developed, philosophy has come to identify a set of features and aspects that are thought to be associated with the various elements of consciousness. On the other hand, there have been several recent attempts to develop computational models of consciousness that are claimed to capture or illustrate one or more aspects of consciousness. As a plausible substitute to evalu...
