Title

The effectiveness of mindfulness meditation on the time perception and brain waves using a temporal bisection task in the student population

Pages

  33-47

Abstract

 Introduction: Time perception is a category stimulating intelligent human curiosity for scientific manipulation and cognition. The present study aimed to investigate the effects of Mindfulness on the Time perception and Brain waves using the temporal bio-section task. Methods: This research was carried out using a randomized controlled clinical trial, which was lasted from autumn 2018 to 2020. One hundred forty-three students of the Science and Research Branch of Islamic Azad University participated voluntarily in the experiments. In a structured clinical interview for the DSM-5 (SCID-5-CV) psychiatric disorder, thirty-one undergraduate students were assessed for mental health and brain disease. Their Mindfulness ability was moderate based on the Freiburg questionnaire, and they were assigned randomly into experimental and control groups, containing sixteen and fifteen participants, respectively. The experimental and control groups were played a 13-minute Mindfulness audio file and a neutral file. 19-channel EEG signals during the temporal bio-section task were recorded from participants, while the power of Brain waves in different frequency bands in channels C3, C4, Cz, F3, F4, Fz, and Pz was calculated before and after presenting the independent variable in two groups. Results: The results showed an increase in beta, delta, and theta power in different channels. Alpha power changes were obtained inconsistently. The gamma power and theta to beta ratio were significantly reduced in the experimental group. Behavioral findings showed an increase in the number of long responses (Percentage long response) and a decrease in the bio section point (Bisection point). Conclusion: The results revealed that the variable of Mindfulness is influential in the process of cognitive processing of Time perception and causes overestimation in Time perception by changing the above electrophysiological measures, which indicate a decrease in arousal, increased internal concentration, increased motor inhibition, and increased physical awareness and emotional regulation.
