Cognitive Dissonance

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

The Stanford Prison Experiment

The Stanford Prison Experiment

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

Naturalistic Observations

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Nightmares and Night Terrors

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.
Nightmares often...

Understanding Sleep

Understanding Sleep

Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Stages of Sleep

Stages of Sleep

Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...

Summary

This summary is machine-generated.

Soldiers in Basic Combat Training (BCT) report poor sleep quality and duration due to noise, stress, and duties. This sleep disruption negatively impacts performance and mood, especially for less fit individuals.

Area of Science:

Military Medicine
Sleep Science
Psychological Health

Background:

Basic Combat Training (BCT) is known to cause sleep impairment.
This sleep disruption may affect soldier health, attrition, and training effectiveness.
Empirical research on sleep during BCT is limited.

Purpose of the Study:

To qualitatively assess soldiers' perceptions of sleep during BCT.
To understand the perceived consequences of sleep disruption in this environment.

Main Methods:

Focus group discussions were conducted with male and female soldiers (n=66) who had completed at least 4 weeks of BCT.
Sessions lasted 45–60 minutes and took place in November/December 2010 at Fort Jackson, SC.

Main Results:

Soldiers reported decreased sleep duration and quality.
Attributed causes include noise, nighttime duties, stress, and hunger.
Negative effects on performance, mood, and BCT components were perceived, particularly in lower-fit soldiers.

Conclusions:

Sleep disturbances are a significant concern during Basic Combat Training.
Perceived negative impacts on soldier performance and well-being are evident.
Further investigation is needed to determine if BCT sleep environments require modification.
