Order of brain waves are: (5)

A
  • Beta – awake/REM – fast and short
  • Alpha – drowsy
  • Theta – stage 1 – light sleep
  • Sleep spindles – stage 2 – hard to wake up

21
Q

Order of brain waves

A
  • Beta – awake/REM – fast and short
  • Alpha – drowsy
  • Theta – stage 1 – light sleep
  • Sleep spindles – stage 2 – hard to wake up
  • Delta – stages 3 and 4
22
Q

Functions of sleep: (9)

A
  • temperature dips
  • levels of hormone cortisol (responsible for stress) dip at bedtime and increase overnight to allow alertness in the morning
  • improve problem solving and learning
  • memory consolidation/organization so you can find them
  • creativity/problem solving
  • General body recuperation (tissue growth and repair)
  • appears to strengthen immune system
  • washing toxins
  • Memory consolidation
23
Q

Memory consolidation studies suggest that REM and slow-wave sleep contribute to…

A

firming up learning that takes place during the day

24
Q

Not sleeping → leads to… (5)

A
  • Emotional volatility/inhibition
  • impairs attention (ability to focus, not notice)
  • Motor coordination
  • Impairs immunity
  • Cognition impaired (cognition = Memory/Learning/Attention/Problem solving)
25
Q

Sleep deprivation can impair… (4)

A

can impair reaction time, attention, motor coordination, and decision making

26
Q

Selective deprivation is when you are deprived of only… but…

A

deprived of only REM sleep but sufficient amount of non-REM – has little repercussions on daytime functioning

27
Q

Alcohol makes you… in stages ___ & 4

Depressant: Activates inactive parts of you, inhibits new memory formation

A
  • Makes you sleep longer in stages 3 & 4 (NonREM)
  • Decrease REM → REM sleep necessary
  • Hormone inhibition
28
Q
  1. Insomnia is the…

And results from…

A

most common sleep disorder
- refers to chronic problems in getting adequate sleep that results in daytime fatigue and impaired functioning – three different patterns include: trouble falling asleep initially, difficulty maintaining sleep, and persistent early morning awakening

29
Q
  1. Narcolepsy is…

and goes directly from ___ to ___ sleep

A

falling asleep without warning – goes directly from wakefulness to REM sleep

30
Q
  1. Sleep apnea is when…
A

a person briefly and frequently stops breathing during the night – wakes the person up back to stage 1 or 2

31
Q
  1. Night terrors is … and happens toward the ___ of sleep
A

in stage 3 & 4 – don’t remember – common in toddlers and college students – happen more towards the beginning of sleep (when more nonREM sleep occurs)

32
Q
  1. Nightmares is during ___ sleep
A

during REM sleep – remember them – happen closer to the morning (when more REM sleep takes place)

33
Q
  1. Sleepwalking is during ___ sleep
A

during deep sleep (nonREM) – do not remember

34
Q

Dreaming (3 Theories)

A
  1. Wish fulfillment → (Freud)
  2. Problem Solving → (Cartwright)
  3. Activation synthesis model → (Hobson & Mccarley)
35
Q
  1. Wish fulfillment → (Freud)
A
  • The days residue shapes dreams to satisfy unconscious desires
  • believed that the purpose of dreams was wish fulfillment – people fulfill unmet or suppressed needs from waking moments (food you wanted to eat, people you want to have sex with, etc.)
36
Q
  1. Problem Solving → (Cartwright)
A
  • Think about major problems in our lives
  • believed that dreams help us work through problems we were not able to solve during the day – named the problem solving/mood regulation view – dreams allow people to engage in creative thinking about problems because dreams are not restrained by logic or realism – contributes to improvement in mood – think about major problems in our life
37
Q
  1. Activation synthesis model → (Hobson & Mccarley)
A
  • “Cerebral cortex synthesis” Neurons firing randomly, Brain has ambiguity so it makes randomness into story
  • dreams are side effects of the neural activation that produces beta brain waves during REM sleep that are associated with wakefulness – brain fires random signals so a dream is merely the brain trying to make sense of the signals (does not like randomness)
38
Q

Hypnosis → requires…

And is a…

A

requires invitation, teamwork, emotion
Altered state of consciousness brought on by spatial techniques; procedures responsiveness to suggestions for changes un experience behaviors

39
Q

Effects on people that are susceptible to hypnosis: (7)

A
  • Anesthesia
  • Sensory distortions and hallucinations
  • Disinhibition
  • Posthypnotic suggestions and amnesia

  • Aid memory:
40
Q

Theories of hypnosis: (3)

A
  • Role playing:
  • Altered state of consciousness:
  • Dissociation
41
Q

Psychoactive drugs are… that modify… (3)

A

42
Q

Physical dependence with drugs exists when…

A

a person must continue to take a drug to avoid withdrawal illness– body needs it to feel normal

43
Q

Psychological dependence with drugs exists when…

A

a person must continue to take a drug to satisfy intense mental and emotional cravings– feel like you need to have it or something is wrong

44
Q

Reward pathway is the… associated with…

A

dopamine addiction associated with habits/drugs

45
Q

Direct effects of the Reward pathway: (1)

A

damage tissue directly
– ex. snorting cocaine can damage nasal tissue directly and known to be associated with a number of respiratory problems and alcohol is related to risk of liver diseases and cancer

46
Q

Indirect effects of the Reward pathway: (1)

A

impact of behavior

    • often people using sedatives do not eat or sleep properly
    • alcohol contributes to about 40% of motor vehicle deaths
