Abstract

Introduction: Alpha frequency band in the range of 8-12 Hz is associated with cognitive functions, such as creativity. The aim of this s tudy was to examine the activity of the alpha frequency band in two divergent and convergent Thinking positions. Materials and Methods: In accordance to the available sampling and voluntary participation, thirty-eight pos tgraduate s tudents of the Ferdowsi University of Mashhad (19 males and 19 female) were chosen. Two subjects were excluded from the analysis due to artifacts in their Brain waves. This s tudy was a quasi-experimental research with repeated measures. The EEG was recorded during the performance of four tasks (alternative uses tes t, counting the snakes, counting numbers tes t, and Missionaries and Cannibals task) in two divergent and convergent Thinking. Results: The findings revealed that there is no significant difference between the activity of alpha waves in the left and right hemispheres in divergent Thinking as well as in convergent Thinking. In addition, the results of the analysis of variance of repeated measures indicated that in divergent Thinking activity of alpha waves in the temporal, central and frontal areas were synchronized, while in the convergent Thinking position de-synchronization of alpha waves was observed. Conclusion: Alpha band power changes in two divergent and convergent Thinking positions represented of different functional mechanisms of alpha waves in these two Thinking positions in different regions of the Brain.
