Abstract

Background and Objective: This study aimed to determine the effect of synchronization of brain waves in alpha, beta, and theta bands by the Binaural beats on visuospatial working memory. Materials and Methods: The present quasi-experimental study was conducted based on a pretest-posttest control group design. In this regard, 60 students were selected by the available sampling method and randomly divided into three experimental groups and one control group (n=15 each). All subjects were assessed in the pre-test and post-test stages by the Corsi blocks tapping test. Participants in the experimental groups received 15, 9, 5, and 6 Hz binaural beats for 12 min. The collected data were analyzed using a one-way analysis of covariance. Results: The findings showed that 15 Hz binaural beats (beta bands) significantly improved the subject's visuospatial working memory (P<0.05). Conclusions: Given that working memory is the basis of numerous cognitive functions, using 15 Hz binaural beats could improve the visuospatial working memory in these people

双耳节拍在Alpha、Beta和Theta波段的脑电波同步对视觉空间工作记忆的影响

背景和目的：本研究旨在确定双耳节拍同步α、β和θ波段的脑电波对视觉空间工作记忆的影响。材料和方法：本准实验研究基于前测后测对照组设计进行。在这方面，通过现有的抽样方法选择了60名学生，并将其随机分为三个实验组和一个对照组（每组n=15）。所有受试者在测试前和测试后阶段均通过Corsi块敲击测试进行评估。实验组的参与者接受15、9、5和6 Hz的双耳搏动，持续12分钟。使用协方差的单向分析来分析收集的数据。结果：15Hz双耳搏动（β带）显著改善了受试者的视觉空间工作记忆（P<0.05）
