A

Subjective awareness of internal and external stimuli

2
Q

External Stimuli

A

What’s happening around you (senses)

3
Q

Attention

A

Process if seeking out stimuli an focusing on them

Different from simply being aware if internal or external stimuli

4
Q

Allocation of mental resources

A

Selective about information that is processed, we pick and choose what’s important and what we process

5

Dichotic Listentng

A

Hearing two messages at the same time

6

Cocktail Party Effect

A

Shifting attention when you hear something personally meaningful ex. Your name at a party

7
Q

Change Blindless

A

Failure to detect changes in a scene when the alteration coincides with a brief visual destruction.
Occurs even when instructed to look for change
Monty Python video

8
Q

Inattentional Blindness

A

Inability to notice a new event while attending to another event
Gorilla video
Driving so focused you can’t see the pedestrian

9
Q

Dual Task Interference

A

Stroop Task: your reading ability interferes your ability to just see the color
Ability to perform one skill interferes with your ability to complete another task

10
Q

Electroencephalogram (EEG)

A

Measures changes in brains activity over time

11
Q

Electromyogram (EMG)

A

Measures muscle time and gives I formation about the muscles

12
Q

Electrooculogram (EOG)

A

Measures eye movements and shows where you’re looking

13
Q

Awake: Beta Waves

A

Alert
Small amplitude
Desychrinized pattern

14
Q

Awake: Alpha Waves

A

Relaxed or eyes closed
Bigger amplitude
Pattern is more synchronized

15
Q

Sleep: Stage 1

A

Transition between sleep and wakefulness
Theta activity
Lasts about ten minutes
Theta waves

16
Q

Sleep: Stage 2

A

Theta activity
Sleep spindles
K Complexes: large waves (1 per min)
Lasts about 15 minutes

17
Q

Sleep: Stage 3 and 4

A
Delta activity (large amplitude, low frequency) 
Stage 3: 20%-50% delta
Stage 4: >50% delta
Hard to wake people, groggy
Thoughts, images; some dreaming 

Stages 1-4 last about 90 minutes

18
Q

B
A
T
D

A

B- beta, being awake and alert
A- alpha, relaxed eyes closed
T- stage 1, stage 2, (+ K complexes, spindles)
D- delta, stages 3&4
B A T D
Short for bad, K and D stand for dark knight, but the K is next to the bat

19
Q

Rapid Eye Movement (REM) sleep

A

EEG resembles alertness (dream sleep)
Muscle paralysis
Genital activity

20
Q

Sleep Patterns: first half of the night

A

More slow wave sleep

21
Q

Sleep Patterns: second half of night

A

More REM sleep

22
Q

REM Rebound

A

You spend more time in REM sleep after a period if deprivation

23
Q

Freud Wish Fulfilment

A

Manifest content vs latent content (latent is dream meaning/message)

24
Q

Activation-Synthesis Hypothesis

A

Beta waves show your brain is really active in this stage

Synthesis: your brain is trying to make sense of this randomness and create a story

25
Q

Memory Hypothesis

A

Consolidation (more complex tasks)

26
Q

Functions of Slow-Wave sleep (deep sleep)

A
Repair body (protein synthesis)
Recovery from intense mental activity
Memory consolidation (simpler tasks)
27
Q

Sleeping Disorder: Bruxism

A

Clenching or grinding of teeth during sleep

28
Q

Sleeping Disorders: Sleep Apnea

A

Cessation of breathing during sleep
CO2 levels in bloodstream increase
Medulla detects the rise of CO2 and wakes you up
Cause: there’s a construction in the airway preventing breathing
Treatment: diet, exercise, special pillows or pjs, pressured air, surgery

29
Q

Narcolepsy: Sleep Attack

A

Irresistible urge to fall asleep then wake up refreshed

30
Q

Narcolepsy: Cataplexy

A

People lose muscle time when they get excited or caught by surprise and they lose muscle control

31
Q

Narcolepsy: Sleep Paralysis

A

Become paralyzed as you’re falling asleep or waking up, symptoms of REM occur at inappropriate times

Can be accompanied by hypnagogic(falling asleep) or hypnopomic(waking up). Hallucinations so when you wake up you broke paralysed and see your dream

32
Q

REM without Atonia

A

Lack if paralysis in REM sleep

Act out dream

33
Q

Slow-Wave Sleep Disorders: Somnambulism

A

Sleep walking

34
Q

Slow-Wave Sleep Disorders: Night Terrors

A

More common in Children
NightMARES occur during REM
Terrors children wake up screaming and by the time their parents come they can’t remember why
