Introduction: In the digital landscape, creativity—considered a higher-order cognitive function—plays a vital role in knowledge application and problem-solving. This study aimed to compare the effectiveness of binaural beat stimulation based on alpha and gamma waves combined versus separate alpha and gamma stimulation in enhancing creativity, working memory, and information processing speed among individuals aged 25 to 40.
Methods: This quasi-experimental study involved 48 students, selected through convenience sampling and randomly assigned to three groups: Gamma wave, alpha wave, and combined alpha-gamma stimulation. Data collection instruments included the Torrance Test of Creative Thinking, the N-Back working memory test, and the Symbol Digit Modalities Test (SDMT) for assessing information processing speed. The data were analyzed using mixed-design analysis of variance (Mixed ANOVA).
Results: The findings revealed that in all groups, the mean scores for working memory and information processing speed significantly increased during the post-test and follow-up phases compared to the pre-test (P≤0.05). However, no significant differences were found among the groups for any of the measured variables (P≥0.05).
Conclusion: The present study suggests that binaural beat-based interventions may enhance cognitive functions, including working memory and information processing speed. However, combined alpha-gamma stimulation did not show a significant advantage over the individual frequency conditions. These findings may inform the development of innovative educational and cognitive rehabilitation strategies.
