Objective: The objective of this study was to find out the effect of mental fatigue on memory (Immediate and 24 hours memory) and retention. Material and method: 60 subjects were recruited. They were divided in two groups i.e. group A (30 subjects) and group B (30 subjects). Group A was administered with three tests (trail making test, 2n-back test, tower of London task). 5 exercises were taught immediately after the completion of these tasks. Subjects were asked to repeat the taught exercises after 1 hour with a video recording done. 2nd reading was taken after 24 hours. On the other end in group B a documentary was shown to the subjects in subgroup of 5-10. Same exercises were demonstrated and readings were taken after 1 hour and 24 hours. Data analysis and results: In the present study Unrelated t-test was used to compare the scores between experimental and control group. Related t-test was used to compare the scores within the groups. From data analysis and results it was revealed that mental fatigue reduces memory and retention. Conclusion: Fatigue results in greater loss of memory (immediate and 24 hours memory) and retention
