These<br />subjects were allowed for 60 minutes retention interval. Later the subjects in daytime nap group were put to bed in a sound attenuated sleep<br />chambers to enable napping while control group was kept awake. Performance of declarative memory was evaluated both pre and post intervention<br />for all subjects by three tests namely, unrelated paired associates, maze learning, and the Rey–Osterrieth complex figure.<br />Results: Statistical analysis revealed that independent t-value was significant between napping and awake group on memory task performance<br />conducted before and after 60 minutes retention interval (p<0.001). Sleep parameters analysis in napping group show sleep onset latency time<br />of 10.6 minutes, which was dominated by Stage I sleep with sleep efficiency of 56.35%. Total sleep time was 51.46 minutes in napping group.<br />Improvement in memory task was statistically significant as the results of unrelated word pair’s associates the performance of nap group was 97.2%<br />when compared with the control group with 90% performance. Rey–Osterrieth complex figure test results show the average time taken by nap group<br />was 45 seconds, and that of awake group was 63 seconds. In the case of maze learning task, the time taken by nap group was 27.33 seconds and by<br />awake group was 38.2 seconds (p<0.001).<br />Conclusion: From the results it is evident that non declarative memory is well enhanced by daytime napping shown by improved performance tests.<br />This might be brought about by memory consolidation process triggered during sleep onset latency.<br />Keywords: Daytime nap, Non-rapid eye movement sleep, Memory consolidation, Declarative memory task.</p>}, number={1}, journal={Asian Journal of Pharmaceutical and Clinical Research}, author={A, CHRISTY and m, DIVYA and A, SARAVANAN and S, VADIVEL and K, Jaiganesh}, year={2015}, month={Jan.}, pages={161–163} }
