Sleep restriction studies have shown that:
A)research participants adapted to the four-hour-per-night sleep schedule by the end of the first week and showed no cognitive or physical impairments over the course of the experiments.
B)there were some beneficial effects in terms of memory consolidation, reaction time, and immune system functioning.
C)immune system functioning, concentration, vigilance, reaction time, memory skills, and ability to gauge risk were all diminished.
D)there is no evidence to support the notion that REM and NREM sleep deprivation result in REM and NREM rebound effects.

Question

Quizplus · Accepted Answer

Sleep restriction studies have consistently shown that restricting sleep to 4-6 hours per night over several nights results in decreased immune system functioning, reduced concentration and vigilance, slowed reaction time, impaired memory consolidation, and reduced ability to gauge risk. These effects typically accumulate over time, rather than adapt or disappear as the study progresses. While there may be some short-term benefits in terms of increased alertness or reaction time, these effects are typically overshadowed by the negative consequences of sleep restriction. Additionally, there is evidence to suggest that both REM and NREM sleep deprivation result in rebound effects, where the individual experiences increased REM and NREM sleep in subsequent nights to make up for lost sleep.
