Abstract

Daytime napping is a frequent habit of many individuals. Research findings suggest beneficial effect of nap on declarative memory consolidation in humans (Gujar et.al. 2010). The present study aims to investigate the role played by nap in object specific recognition memory. The objective of the present study is to evaluate the role played by nap in object specific retrieval of declarative memory. Ten healthy participants (22.5 years) divided into nap and control group volunteered for the study. On experimental day the participants arrive at laboratory at 12.00 h performed encoding (learning phase) of behavioral task followed by hnap/wakefulness retention interval of 60 minutes & subsequent retrieval phase. Repeated measure ANOVA [2 (condition nap, wake x 2 (stimuli: face, scene) revealed significant main effect for nap [F (1, 9) = 8.687, p = 0.018, μ2 = 0.52] and object [F (1, 9) = 8.51, p = 0.019, μ2 = 0.51]. sleep analysis of nap subjects reported 62.56% sleep efficiency with stage 2 and REM stage domination. Correlations between REM stage & memory accuracy (ρ =.65 scene and ρ =-.28 face) were reported. The findings suggest that recognition memory accuracy is enhanced by napping and scene as compared to face shown better performance.
