Paper Abstract:	The purpose of this study is to probe the difference of cognitive processes in different mental rotation ability (MRA) levels during mental rotation tasks. The study group is consisted of 10 undergraduate students from Psychological Counseling and Guidance Department at Hacettepe University. Firstly, participants’ mental rotation ability levels were determined. Secondly, participants were put in groups in terms of their mental rotation test scores. Then they were given two digital tangram problems with different difficulty levels. During their interaction with Tangram problems their eye movements were recorded. Mann Whitney U test was conducted to evaluate differences in eye movements of different mental rotation ability level groups. As a result, it was found that while there were significant differences in eye movement between different mental rotation ability levels for easy tangram problem, there were no significant difference in eye movements for difficult tangram problem. In addition, examining completion time showed that while easy tangram problem completion time was significantly shorter for people with higher score in mental rotation test, there were no significant differences between completion times of different level mental rotation ability groups for difficult tangram problem. Since spatial ability is an important predictor of task performance and completion time, it can be suggested that adaptive learning environments should be designed to compensate for low MRA level learners.
