Objective: This study aims to investigate the effects of memory training and recitation as cognitive activity on episodic memory performance. We chose memorization of the Koran as a model. Methodology: two groups of 50 participants, matched by age, school level, and gender were compared. The experimental group memorized the entire Koran and recited it regularly. Subjects with a history of psychiatric or neurological disorders, as well as those with hearing, visual, or language impairment were excluded from the study. To assess episodic memory in both groups, we administered the Reduced Memory Efficiency Battery 84. Results: Statistical data showed that participants who memorized and recited the Koran obtained better performance in episodic memory compared to the control group. Conclusion: This study demonstrates the beneficial effect of memorizing the Koran as a cognitive training activity characterized by repetition and retention on episodic memory performance. Further research is necessary to explore the impact of such memorization activities on various aspects of cognitive functioning and their underlying mechanisms.
