Researchers at State University conducted some carefully controlled sleep restriction studies. Their results are likely to demonstrate that:
A) research participants will easily adapt to the four-hour-per-night sleep schedule by the end of the first week and will show no cognitive or physical impairments over the course of the experiments.
B) there will be some beneficial effects in terms of memory consolidation, reaction time, and immune system functioning in the majority of participants.
C) immune system functioning, concentration, vigilance, reaction time, memory skills, and ability to gauge risk will be diminished in most participants.
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

The carefully controlled sleep restriction studies are likely to demonstrate that participants will experience negative effects on immune system functioning, concentration, vigilance, reaction time, memory skills, and ability to gauge risk due to the sleep deprivation. This is based on previous research that shows the negative impacts of sleep deprivation on cognitive and physical functioning. Option A is unlikely since research shows that sleep deprivation negatively impacts cognitive and physical functioning, while option B is unlikely to be the majority experience. Option D is also incorrect as there is evidence to support the notion of REM and NREM rebound effects.
