Evolutionary theory, also known as the adaptive theory of sleep, suggests that periods of activity and inactivity evolved as a means of conserving energy. According to this theory, all species have adapted to sleep during periods of time when wakefulness would be the most hazardous.
Consequently, what is the relationship between memory consolidation and sleep quizlet?
What is the relationship between memory consolidation and sleep? During sleep, consolidation occurs with repeated hippocampal activation of cortical areas. During sleep, fewer than 50 genes are needed to increase their activity for consolidation to occur.
Regarding this, what mental state involves focusing your attention on yourself as an object?
Self-awareness involves being aware of different aspects of the self including traits, behaviors, and feelings. Essentially, it is a psychological state in which oneself becomes the focus of attention.
What mental state is described in the textbook as being a distinct level of consciousness in which a person’s attention is drawn to the self as an object?
What mental state is described in the textbook as being “a distinct level of consciousness in which [a] person’s attention is drawn to the self as an object”? William James’s description of consciousness as a stream illustrates the property of: unity. transience.
What role does sleep play in memory during sleep memories are consolidated for storage?
Research suggests that sleep helps learning and memory in two distinct ways. First, a sleep-deprived person cannot focus attention optimally and therefore cannot learn efficiently. Second, sleep itself has a role in the consolidation of memory, which is essential for learning new information.
What role does sleep play in memory quizlet?
Sleep supports memory consolidation. During deep sleep the hippocampus processes memories for later retrieval. Working on a study then sleep then study schedule improves memory function.
What role does sleep play in memory?
“During a night of sleep, some memories are strengthened.” Research has shown that memories of certain procedures, like playing a melody on a piano, can actually improve while you sleep. Memories seem to become more stable in the brain during the deep stages of sleep.
Which method is used to monitor and record eye movements during sleep?
Polysomnography, also called a sleep study, is a comprehensive test used to diagnose sleep disorders. Polysomnography records your brain waves, the oxygen level in your blood, heart rate and breathing, as well as eye and leg movements during the study.
Which of the following is a characteristic of REM sleep quizlet?
REM brain waves have fast frequency and low amplitude and look very similar to beta waves, which occur when you are wide-awake. During this stage your body is physiologically aroused, but your voluntary muscles are paralyzed. REM sleep stage is highly associated with dreaming.
Which theory of sleep suggests that sleep is a by product of evolution and protects the sleeper from harm and also explains when we sleep?
One of the earliest theories of sleep, sometimes called the adaptive or evolutionary theory, suggests that inactivity at night is an adaptation that served a survival function by keeping organisms out of harm’s way at times when they would be particularly vulnerable.
Which theory suggests that we sleep to rest our bodies and minds and rejuvenate ourselves for the next day?
The restorative theory states that sleep allows for the body to repair and replete cellular components necessary for biological functions that become depleted throughout an awake day.
