Abstract

In cognitive ergonomics, study on sleep deprivation has received considerable attention in the literature. Researchers studied length and timing of sleep and its relationship with several variables. Present study aimed to examine student’s stress level, sleep debt, and vigilance in doing Master study at university. Life stress questionnaire, sleep diary, NASA task load index and psychomotor vigilance test were used to measure the variables. A 10-day observation shows that duration of sleep did not have significant linier correlation with vigilant attention. However, the postgraduate learning task was perceived to be stressful and ‘mental demand’ contributed to be the most weight factor in NASA workload index. Moreover, it was also perceived as a ‘temporal demand’ in the workload rate rating. Critical review, limitations, suggestion and reflection were also discussed in the present study.
Keywords: Stress, Sleep Deprivation, Psychomotor vigilance test, NASA task load index.
