What was the aim of Dement and kleitman experiment?
Aim. Dement and Kleitman’s research aimed to find objective methods to demonstrate a relationship between dream content and physiological indicators of dreaming. Specifically, they wanted to investigate: Does dream recall differ between REM and nREM stages of sleep.
What is the psychology being investigated in the Dement and kleitman study?
The Psychology Being Investigated: – This study investigates the sleep stage and the dreams that occur. – The duration of a dream during REM stage. – The patterns of eye movement during REM. – The direction of movement and the correlated content of the dream.
What did Dement and Wolpert discover during their experiment?
The following year, Dement and Wolpert19 first showed that episodes of this sleep stage increase in duration during the night and that there is a relationship between body movements and the changing of dream content. These sleep periods did not last for more than 10 minutes.
IT has been suggested that patterns of physiological activity during rapid eye movement (REM) sleep are directly related to concurrent dream experiences1–4. Thus visually “active” dreams are associated with more REM activity than are “passive” dreams involving little visual activity2,5.
What happens during NREM?
During the deep stages of NREM sleep, the body repairs and regrows tissues, builds bone and muscle, and strengthens the immune system. As you get older, you sleep more lightly and get less deep sleep.
Why is REM sleep also known as paradoxical sleep?
The REM phase is also known as paradoxical sleep (PS) and sometimes desynchronized sleep, because of physiological similarities to waking states including rapid, low-voltage desynchronized brain waves.
What technique is used to measure brain activity in Dement and Kleitman?
From the study by Dement and Kleitman (sleep and dreams): Name the technique used to measure brain activity. The technique used to measure brain activity was an EOG. You just studied 13 terms!
How does the body physiologically respond to REM sleep?
As you cycle into REM sleep, the eyes move rapidly behind closed lids, and brain waves are similar to those during wakefulness. Breath rate increases and the body becomes temporarily paralyzed as we dream.
How do the eyes move in REM?
Also known as paradoxical sleep, REM sleep causes the eyes and brain to act in a way similar to a waking state. During non-REM sleep, the eyes may move in the opposite direction from one another. During REM sleep, the eyes tend to “look” at the same area, just like they would in a fully awake state.
What is the purpose of sleep spindles?
Sleep spindles are an electroencephalographic (EEG) hallmark of non-rapid eye movement (NREM) sleep and are believed to mediate many sleep-related functions, from memory consolidation to cortical development.
What does NREM stand for?
Non-REM (NREM) sleep Non–rapid eye movement (NREM) sleep has 3 stages: Stage N1 occurs right after you fall asleep and is very short (usually less than 10 minutes). It involves light sleep from which you can be awakened easily.
