Purpose: Binaural beats are a therapy method that uses the difference in frequencies between the left and right ears to maximize brain waves. There are five types of brain waves: delta, theta, beta, gamma, and alpha, with alpha representing a relaxed state of consciousness and serving as the focus of this research. This research aimed to determine whether binaural beats on alpha brain waves affect the working memory of students from the Faculty of Psychology, Padjadjaran University, class 2023.
Methodology/approach: This quantitative research used an experimental research design in the form of a one-group pretest-posttest design using a sampling technique in the form of stratified random sampling. This research uses the Brown Peterson Task measurement tool, which was conducted in November 2023, involving 50 respondents from the Faculty of Psychology Unpad students’ class of 2023 using the Wilcoxon test statistical analysis.
Results: After conducting statistical tests on the pre-test and post-test data with the same participants, the researcher found that the average post-test score (total = 50; M = 4.38; SD = 1.50) was higher than the average pre-test score (total = 50; M = 4.00; SD = 1.47). Based on Wilcoxon testing, the post-test scores for the Brown-Peterson task were higher than the pre-test scores for the Brown-Peterson task.
Limitations: This study has several limitations. The use of a pre-test and post-test strategy in the Brown-Peterson Task may yield results influenced by participants' familiarity with the instructions and questions in the pre-test. Therefore, it is recommended that future research should introduce more variation in the post-test to control for the obtained results. The population and sample size of this study are limited, and subsequent research is expected to broaden the population scope and increase the sample size to support the generalization of the results.
Contribution: This study contributes to students by considering techniques for improving their working memory abilities.
