en Cognition پژوهشي Research Article <strong>Background and Objective: </strong>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. <pre> <strong>Materials and Methods:</strong> 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.</pre> <pre> <strong>Results:</strong> The findings showed that 15 Hz binaural beats (beta bands) significantly improved the subject&#39;s <a name="_Hlk50373683">visuospatial</a> working memory (P<0.05).</pre> <strong>Conclusions:</strong> 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 working memory, brain waves, cognitive functions 186 191 http://ajnpp.umsha.ac.ir/browse.php?a_code=A-10-370-1&slc_lang=en&sid=1 Ezzatollah Ahmadi amiraliahmadi91@yahoo.com 10031947532846005217 10031947532846005217 Yes Associate Professor, Department of Psychology, Azarbaijan Shahid Madani University, Tabriz, Iran Hassan Bafandeh Gharamaleki h_bafandeh@yahoo.com 10031947532846005218 10031947532846005218 No Associate Professor, Department of Psychology, Azarbaijan Shahid Madani University, Tabriz, Iran Siamak Dadashi siamakdadashi94@gmail.com 10031947532846005219 10031947532846005219 No PhD student of Cognitive Neuroscience, Division of Cognitive Neuroscience, University of Tabriz Habibollah Rasouli rasouli_habib@yahoo.com 10031947532846005220 10031947532846005220 No MSc in Cognitive Science, Department of Psychology, Azarbaijan Shahid Madani University, Tabriz, Iran
