Exploring hand movement dynamics during the Simon task: a mouse tracking study.

İkizoğlu, Hatice Buke
Understanding how the cognitive system processes information in real-time is one of the key concerns for researchers in experimental psychology and cognitive science. Several measures and software tools have been proposed to explore different aspects of cognitive processing phenomena. One of these methods, mouse-tracking, allows researchers to collect data about the dynamic unfolding of motor responses by recording the participants’ mouse movements during cognitive tasks. In the present study, we replicated the Simon effect, which is known as the “stimulus-response compatibility effect” in a Mouse tracking paradigm. We investigated the impact of design factors on Mouse-tracking data by placing the response alternatives at the bottom corners rather than at the top. We also performed an additional experiment, including the reverse Simon Effect. Consistent with previous studies, the mouse tracker experiments conducted in this thesis showed a significant stimulus-response compatibility effect while the response directions towards the left and right corners are not entirely symmetric in the conflict cases. On the other hand, switching the response mapping to top-to-bottom has increased the asymmetry between left and right cases during conflict trials. Lastly, the reversal effect was observed vividly in the case of y-flips, which seemed to be the best indicator for the process of adjusting to the new color-response pairing.


A philosophical analysis of computational modeling in cognitive science
Ürgen, Burcu Ayşen; Bağçe, Samet; Department of Cognitive Sciences (2007)
This study analyses the methodology of computational cognitive modeling as one of the ways of conducting research in cognitive science. The aim of the study is to provide an understanding of the place of computational cognitive models in understanding human cognition. Considering the vast number of computational cognitive models which have been just given to account for some cognitive phenomenon by solely simulating some experimental study and fitting to empirical data, a practice-oriented approach is adopt...
Evaluating working memory capacity and cognitive load in learning from goal based scenario centered 3D multimedia
Kilic, Eylem; Yıldırım, Zahide (2010-02-08)
The purpose of this study is to investigate working memory capacity and cognitive load in learning from Goal Based Scenario centered 3D multimedia learning environment (GBSc3DM) designed based on Cognitive Load Theory (CLT). GBSc3DM was developed in two versions. In the designed of the first version (+CLT) cognitive load principles were applied. In the second version (-CLT), however, the principles were violated. 47 11(th) grade high school students were selected based on their working memory capacity (WMC)...
Learning transferability of cognitive tasks by graph generation for brain decoding
Coşkun, Bilgin; Yarman Vural, Fatoş Tunay; Department of Computer Engineering (2021-12-10)
Brain decoding involves analyzing the cognitive states of human brain by using some statistical techniques in order to understand the relations among the cognitive states, based on neuroimaging data. A very powerful tool to acquire the brain data is functional magnetic resonance images (fMRI), which generates three-dimensional brain volume at each time instant, while a subject performs a cognitive task involving social activities, emotion processing, game playing, memory etc. However, it is very difficult a...
Tracing users' behaviors in a multimodal instructional material: An eye-tracking study
Yecan, Esra; Sumuer, Evren; Baran, Bahar; Çağıltay, Kürşat (2007-07-27)
This study aims to explore user behaviors in instructional environments combining multimodal presentation of information. Cognitive load theory and dual coding theory were taken as the theoretical perspectives for the analyses. For this purpose, user behaviors were analyzed by recording participants' eye movements while they were using an instructional material with synchronized video and PowerPoint slides. 15 participants' eye fixation counts and durations for specific parts of the material were collected....

This study was conducted to examine students' perceptions of collaboration, socialization and task complexity in an online collaborative learning environment. Implementation of the collaborative learning was performed via Google Docs. The study group consists of 43 fourth grade university students who take "Research Methods" course. The students were divided into 11 groups. The students were expected to prepare a research proposal in line with the problem statement which was determined by themselves as part...
