Akış, kişilerin zorlayıcıyken aynı zamanda eğlenceli olan ototelik aktiviteleri gerçekleştirmesi sırasında ortaya çıkar. Akış ile ilgili çalışmalar genellikle kalitatif yöntemlere yoğunlaşırken, akışın psikofizyolojik temelleri üzerine çok az çalışma yapılmıştır. Bu çalışma akışın nöral temellerini araştırmayı amaçlamaktadır. Çalışma kapsamında 20 katılımcı Akış Kısa Ölçeği Türkçe Versiyonu tamamladıktan sonra, EEG kaydı süresince yavaş (sıkıcı) ve hızlı (akış) olmak üzere iki farklı seviyede ping-pong oyunu oynamışlardır. Sonuçlarına göre akış koşulunda akış olmayan koşula göre, teta gücü tüm bölgelerde daha yüksek ve delta gücü ise santral ve parietal bölgelerde daha yüksektir. Koherans için koşullar arasında anlamlı bir farkında bulunamamıştır. Teta ve delta bantları ile Akış Kısa Ölçeği alt ölçekleri arasında pozitif korelasyon saptanmıştır. Teta ve delta bandındaki artış akış durumunun önemli göstergeleri olabilir. Sonuçlar farklı paradigmalar ve hasta gruplarında tekrarlandığı durumda, akış durumunun elektrofizyolojik temelleri performansı ve iyi oluş halini arttırmak için kullanılabilir.
EEG findings during flow state
Flow state emerges when a person engages in autotelic activities, which are both enjoyable and challenging. While studies generally focused on qualitative data of flow state, a few were conducted on psychophysiological basis of it. Present study aimed to investigate EEG correlates of flow. Twenty participants preliminarily filled out Flow Short Scale Turkish Version and completed a ping-pong game at two levels (slow boring and fast-flow) during EEG recording. The results revealed that theta power was significantly greater for all regions during flow condition compared to non-flow condition and delta power was significantly greater during flow on central and parietal regions. There is no difference between flow/non-flow conditions for coherence. A positive correlation was found between delta and theta powers and subscales scores of Flow Short Scale. The increases in these theta and delta frequency bands could be important indicators of flow state. The coherence results revealed that interhemispheric synchronization was not modified by flow. If confirmed with multiple tasks and in clinical groups, EEG correlates of flow state could be useful increase performance and well-being.
