Complete deprivation of sleep has a significant adverse effect on daily human functions
.
It is well known that it affects a range of cognitive functions, including alertness, sustained attention, memory, reaction inhibition, and decision-making
Complete deprivation of sleep has a significant adverse effect on daily human functions
Julie Grèzes et al.
When individuals with anger or fear unrelated to the task existed, subjects (n=34) spontaneously made approach/avoidance decisions during rest or complete sleep deprivation (27 consecutive hours of awakeness)
.
The positive affect scale, negative affect scale, and psychomotor alertness task were used to evaluate sleep-related changes in mood and sustained attention
When individuals with anger or fear unrelated to the task existed, subjects (n=34) spontaneously made approach/avoidance decisions during rest or complete sleep deprivation (27 consecutive hours of awakeness)
Changes in PANAS positive (left) and negative (right) scores under sleep rest and complete sleep deprivation conditions, respectively
.
.
The rested participants avoided fear and angry individuals, and angry individuals avoided stronger, consistent with the previous results
.
In contrast, participants who were completely sleep deprived neither liked approaching nor avoiding fearful people, while they still avoided angry people relatively
The rested participants avoided fear and angry individuals, and angry individuals avoided stronger, consistent with the previous results
The relationship between PANAS positive score and behavior
The relationship between PANAS positive score and behaviorMediation analysis: PVTrt is used as the mediation factor (dPV) to evaluate the relationship between the change in PANAS positive score (dPA) and the change in the fear stimulus away response ratio (dfC)
.
The numbers on each path are the standardized regression coefficients between the variables
Mediation analysis: PVTrt is used as the mediation factor (dPV) to evaluate the relationship between the change in PANAS positive score (dPA) and the change in the fear stimulus away response ratio (dfC)
Overall, the study strongly suggests that individuals who are regularly exposed to total sleep deprivation, such as nurses, doctors, police, and military personnel, may continue to respond adaptively to direct and clear social threats
