Abstract
BACKGROUND: To provide evidence for better understanding stressful situations, the present study was designed to investigate the specific physiological and psychological responses under stressful situations like social isolation and sleep deprivation. METHODS:Twelve healthy male adults (age: 18-30years old) who participated in our study were randomized to the 72hours of social isolation and 72hours of sleep deprivation experimental conditions. Performances (event-related potentials and physiological activities) on the Go/Nogo task which reflected the executive functions were accessed at baseline (pretest) and after 72-hour of the experiment (posttest). RESULTS: The results showed that compared to the social isolation, the participants got strengthened heart rate (HR), weakened HR variability and smaller amplitude of the P300 under the sleep deprivation condition; moreover, they had lower positive emotion and higher negative mood in the posttest. CONCLUSIONS: The present study indicated that sleep deprivation specifically influenced the intensity of task-relevant information processing, mood and vagal tone.
