Q

driver fatigue

spring vs fall time change? contribution % in US?

A

contributes to 20% of all driver-related accidents in the US

  • spring time change -> more accidents
  • fall time change -> less accidents

Q

frauds wish-fulfillment theory

involves? purposes?

A

(erotic wishes)
manifest content: remembered storyline of dream
latent content: underlying meaning
ideas and thoughts are hidden in our unconscious (id)
dreams are key to understanding our inner conflicts

Q

information-processing theory

A

dreams act to sort out & understand the memories that you experience that day (new info take from pile of knowledge and store for long term)
REM sleep does increases after stressful events
ex: Rats in a maze (trained maze, 1 w/ full sleep remembered maze, other woken during REM did not)

Q

Physiological function theories

-Activation-Synthesis Theory

A
  • during night our brainstem releases random neural activity, dreams may be a way to make sense of that activity
  • more limbic system and less frontal lobe… Freud would be happy (has to do w/ id)

Q

Sleep apnea

A

breathing interruption during sleep
gasp for air, breathing again, fall back asleep
tired during day, don’t wake up completely
air passages blocked-> snoring, nasal mask steady flow prevents interruptions
associated w/ snoring and obesity

21
Q

Narcolepsy

A

rare sleep problem where ppl suddenly fall asleep no matter what time or where they are
awake -> REM
genetic disorder of REM sleep functioning
dangerous bc could be doing something important

22
Q

SIDS

A

sudden infant death syndrome
campaign BACK TO SLEEP helped this
known as crib death, death of

23
Q

Insomnia

A

inability to sleep
most common type -difficulty falling asleep
cannot force self to sleep, make worse by trying to sleep
racing minds and worry before bed

24
Q

nightmares

A

products of REM upsetting events can produce these

25
Q

night terrors

A

aka sleep terrors, more severe than nightmares
heart racing, gasp for air, thrash, talk incoherently, sit up
do not wake up, memories usually vague unlike night mares
occur during 3 & 4, first couple sleep cycles, most common in children

26
Q

nightmare vs night terrors

A

nightmare- during REM, toward morning, long story

night terrors- during 3 & 4, vague memory, severe

27
Q

sleepwalking

A

during stages of deep sleep, don’t remember what u did or said
most children go out of it
hereditary, prone to accidentally hurting self

28
Q

3 biological rhythms?

A

annual cycles- seasonal
24 hour cycle-circadian rhythm
90 minute cycle-sleep

29
Q

annual cycles

A
seasonal variations (bears hibernation, seasonal affective disorder)
SAD-during winter, sit infant of mimicking sun
30
Q

24 hour cycle

A

circadian rhythm

  • 5 stages total
    • 1,2,3,4 NREM
    • 5 REM
31
Q

90 min cycle

A

sleep cycles

32
Q

circadian rhythm

def? what changes? how does it change? best to do things when?

A

24 hr biological clock
our body temp and awareness changes throughout the day
-rises as morning approaches
-peaks during day
-dips mid afternoon
best to take a test or study during peaks
(Sunday night insomnia, shift rhythm over lifespan - starts at age 20 earlier for women)

33
Q

lights impact on our circadian rhythm

triggers? where? controls what? released/inhibited? role of caffeine? what happens when we stay awake too long?

A

light triggers light-sensitive retinal proteins
-triggers signal to suprachiasmatic nucleus
-controls the pineal gland
-melatonin released (SLEEP)
-melatonin slows as we wake (ceases to produce)
stay awake… brain produces adenosine (groggy)
-caffeine blocks (inhibitory, antagonist) adenosine (become more dependent) (block it and feel good/awake, crash harder than normally)

34
Q

why do animals wake before humans?

A

animal skulls are thinner, stop producing melatonin when sunlight hits skull-> wake up earlier

35
Q

how many sleep stages are there?

A

5 identified stages of sleep

36
Q

how are sleep stages measured?

A

electroencephalograph

37
Q

how long does it take to pass through 5 stages?

A

90-100 minutes to pass through the 5 stages

38
Q

first four stages of sleep are known as ?

A

NREM sleep

39
Q

fifth stage of sleep is called

A

REM sleep

40
Q

brain waves and stages of sleep

do they stay the same?

A

brain’s waves will change according to stage of sleep you’re in
(dreams occur throughout)

41
Q

stage 1

what happens? waves? how measured? experienced as? what can occur in this stage? called?

A

experienced as falling to sleep and is a transition stage btwn wake and sleep
eyes roll slightly
brief alpha waves, similar to those present while awake (EEG)
HALLUCINATIONS can occur and feeling of falling/floating
-this is called hypnogogic sleep

42
Q

stage 2

A

follows stage 1
baseline of sleep
occupies majority of sleep

43
Q

stage 3 & 4
waves? brain activity? known for (2)?
occurs a lot in?

A

delta sleep, slow wave sleep
brain activity slows down dramatically from theta rhythm of stage 2 to much slow rhythm called delta (rlly slow breathing)
delta- most deepest of sleep (NOT REM) & most restorative
delta sleep is what sleep-deprived person craves
occurs a lot in children “dead asleep” most of night

44
Q

what happens in through stages as sleep goes on?

A

less time in 3/4 & more time in rem

stage 2 occurs most of the time (baseline)

45
Q

stage 5 REM sleep

A

REM: Rapid Eye Movement
very active stage of sleep
breathing, HR, brain wave activity quicken
vivd dreams occur
from rem -> back to stage 2
body is essentially paralyzed during REM, also known as paradox sleep

46
Q

REM disorder example?

A

walking around the room

47
Q

what is used to treat narcolepsy ?

A

amphetamines (stimulants, keep alert)

48
Q

what is used to slow down nervous system, treat insomnia

A

barbiturates (depressant, sleepy)
