-
Circadian Rhythm
The biological clock; regular body rhythms that occur on a 24-hour cycle
-
REM Sleep
Rapid eye movement sleep; a recurring sleep stage that during which vivid dreams commonly occur
-
Who found out about REM Sleep?
Eugene on his 8 year old son Armond Aserinsky with an EEG.
-
What else is REM sleep known as and why?
Paradoxical Sleep because the muscles are relaxed (except for minor twitches) but other body systems are active.
-
Alpha Waves
Relatively slow brain waves of a relaxed, awake state.
-
Sleep
Periodic, natural loss of consciousness
-
Describe William Dement's experiment
- Dement made a sleep deprived young man lie down with his eyelids taped back.
- He told him to press a button everytime a strobe light flashed in his eyes.
- After a few minutes the man missed one and said it was because there was no flash.
- There was a flash, he had just missed it because he fell asleep for 2 seconds.
-
Hallucinations
- False sensory experiences
- Such as seeing something in the absence of an external visual stimulus
-
Delta Waves
Large, slow brain waves associated with deep sleep
-
NREM Sleep
- Non-rapid eye movement sleep
- Encompasses all sleep stages except for REM sleep
-
SCN
- Suprachiasmatic Nucelus
- Pair of cell clusters in the hypothalamus that controls circadian rhythm
- Light intensity causes the SCN to cause the pineal gland to adjust melatonin production, thus modifying our feelings of sleepiness
-
In what stage of sleep are likely to experience hypnagogic sensations of falling?
NREM-1
-
Insomnia
- Persistent problems in falling or stay asleep
- Is not a disorder, it is a symptom for a deeper underlying disorder
-
Narcolepsy
- Sleep disorder with uncontrollable sleep attacks
- The sufferer may lapse directly into REM sleep
-
Sleep Apnea
Sleep disorder with unaware temporary cessations of breathing during sleep and repeated momentary awakenings
-
Night Terrors
- Sleep disorder with high arousal and an appearance of being terrified
- They are seldom remembered
- Targets mostly children
-
How are Night Terrors different from Nightmares?
They occur during NREM-3 sleep, within two or 3 hours of falling asleep and are seldom remembered
-
Dream
Sequence of images, emotions, and thoughts passing through a sleeping person's mind
-
Why do we dream?
(5)
- To satisfy our own wishes
- To file away memories
- To develop and preserve neural pathways
- To make sense of neural static
- To reflect cognitive development
-
Why do we need sleep and what kind of psychologist would say this?
(5)
- To protect us-Evolutionist
- To help us recuperate-Biological
- To help us restore and rebuild our fading memories of the day's experiences-Cognitive
- To feed our creative thinking-Cognitive
- To support our growth-Biological
-
Manifest Content
Remembered storyline of our dreams according to Freud
-
Latent Content
The underlying meaning of a dream according to Freud
-
REM Rebound
The tendency for REM sleep to increase following REM sleep deprivation
-
Consciousness
Awareness we have about ourselves and within our enviroment
-
Being able to process only one conscious thought at a time
Selective Attention
-
Why is daydreaming good?
(2)
- It is healthy and necessary
- We are filing away new memories
-
Most vital portion of sleep
REM sleep
-
When light activates the Penial gland after you just woke up from dreaming what happens?
You won't remember your dream
-
The 5 Stages of sleep is also known as...
The 90 minute cycle
-
Seasonal depression
Seasonal Affective Disorder
-
What is the treatment for Seasonal Affective Disorder?
Phototherapy or light therapy
-
What does the 25th hour have to do with?
Unnatural lighting
-
What makes us finally sleep?
- Light Intensity
- Pineal Gland
- Melatonin
-
How does Light Intensity affect us?
- Light intensity causes us to either increase or decrease melatonin production.
- If it's dark outside melatonin is increased.
- If it's bright outside melatonin is decreased.
-
Why do we fall asleep gradually?
Because Melatonin passes through the bloodstream
-
Stage 1
(5)
- Alpha Waves
- Slowing of breathing
- Increased brain activity
- Lasts about 10 minutes
- Very relaxed state
- Minor Hallucinations
-
Stage 2
(3)
- Beta Waves
- Sleep Spindles-twitches
- Last about 10-15 minutes
-
Stage 3
(2)
- Some say it does not exist because it's so short
- Less than 5 minutes
-
Stage 4
(4)
- Delta Waves
- Deep sleep
- Can occur with eyes open
- Longest stage (lasts about 30-35 minutes)
-
What type of things can happen during Stage 4?
- Sleepwalking
- Bedwetting
- Night Terrors
-
Adult Bed Wetting
Enurisis
-
Hyposomnia
Wants to sleep a lot
-
How to cure Insomnia
(3)
- Exercise
- Eat healthy
- Try to go to bed on the same schedule regularly
-
Theory of Narcolepsy?
It is linked to the lack of the neurotransmitter called Hypocretin.
-
Sleep Apnea treatments?
(3)
- Oxygen Mask
- Removal of Tonsils and Uvula
- Weight loss
-
Night Terror treatments?
None, the child will grow out of it
-
What is the problem with Freudian Dream Theory?
(3)
- He interpreted everyone's dreams differently
- Very unscientific/too vague
- Too much introspection
-
Wish-fulfillment
Dreams provide a psychic safety valve to discharge unacceptable feelings
-
Information-processing
Dreams help us sort out the day's events and consolidate our memories
-
Physiological Function
Regular brain stimulation from REM sleep may help develop and preserve neural pathways
-
Neural Activation
REM sleep triggers neural activity that evokes random visual memories which our sleeping brain weaves into stories
-
Cognitive Development
Dream content reflects dreamers' cognitive development - their knowledge and understanding
