Introduction: Recently, the human dimensions of vulnerability to health, performance and cognitive ability due to sleep deprivation (SD) have received significant attention in psychology, health science, sleep research, cognition and so on. Sleep as a circadian behaviour has profound effect on body restitution, facilitation of motor function, memory, learning and other cognitive domains. A good number of studies have evidenced the effect of sleep deprivation (SD) on psychomotor skills (PMS), a vital cognitive domain. SD impairs psychomotor skills (PMS) considerably, shown by the studies conducted in western cultural context. Yet, pose a concern for not knowing how SD adversely affects PMS amongst the peoples of other cultural context since cultural differences are at play on cognition. Objectives: Our objective of the present study was to investigate the effect of Total Sleep Deprivation (TSD) on Psychomotor Skills (PMS) in Bangladeshi cultural context. Methods: Two randomized group design was followed to collect the data where experimental group (33 adults) was kept totally sleep deprived for 24-hour a day and the control group (36 adults) was kept in normal setting. Crawford Small Parts Dexterity Test (CSPDT) was used to measure the PMS. Results: Results revealed a significant decline in PMS of experimental group who were kept sleep deprived (t = - 2.36, p < 0.05). Results echoes with previous findings in that PMS are the human capability of combination of cognitive and motor processes, skills that are vital for humans at work. Conclusion: The discussion on perception and cultural issues on sleep-cognition issue is important since perception on SD and its effect on cognitive performances has variability in respect of cultural diversity. Human perception is always biased by cultures. The concept of culture and cultural influence on sleep-cognition link is crucial. Human psyche is better understood in the particular cultural setting where the individual lives. The concept of culture is treated as particular society, its specific cultural norms, its people's habit, attitude, perception and learning, and this disconnects the practices, ideas and perceptions prevail in other peoples of different cultural settings. So, the findings of the present study show the viability of studying sleep-cognition link in other cultural context, thus allowing investigators to significantly increase cultural validity over stereotyped data dependency.
