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 question asks about the likely results of a sleep restriction study, and option C presents a comprehensive list of likely negative outcomes such as impaired immune system functioning, reduced concentration, vigilance, reaction time, memory skills, and the ability to gauge risk. As sleep deprivation has been linked to such adverse effects, C is the most appropriate choice. A, on the other hand, is not likely because sleep restriction is generally known to cause cognitive and physical impairments. B is only partially correct because some benefits such as memory consolidation have been reported, but the majority of the effects are likely to be negative. D is incorrect because REM and NREM rebound effects have been observed in sleep-deprived individuals, so the option contradicts research evidence.
