Q

Broadbent filter

A

a model of model of selective attention

  • prevents information overload
  • a selective filter is applied based on physical properties of the sound
  • does not take into account the cocktail party effect

Q

Alan Baddeley’s model

A

working memory consists of 4 components

  1. phonological loop
  2. visuospatial sketchpad
  3. episodic buffer
  4. central executive

phonological - we repeat verbal information to aid memory
visuospatial - mental images
episodic buffer - integrate verbal/imagery with a sense of time, interface with long-term memory, into coherent episodes. seeing a station wagon your father used to drive
central executive - shifting and dividing attention

Q

Jean Piaget’s 4 stages of development

A
  1. sensorimotor (0-2): they sense the world through senses and movement. learn object permanence - existence of objects out of sight
  2. preoperational (2-7): symbols like words and images, pretend play, development of language, but lack logical reasoning, also: egocentric (do not understand other people have perspectives)
  3. concrete operational (7-11): logical thinking about concrete events. principle of conservation (water and shape). mathematical concepts
  4. formal operational (12-adult): abstract reasoning (hypothesizing) and moral reasoning

Q

recall versus recognition

A

recognition is retrieving information from memory with clues

elderly have worse recall, slower reaction times and speech, and harder time with time-based tasks

Q

role of culture/language

A

culture = social processes -> affects how we internalize information

Q

overconfidence

A

over-reliance on heuristics and over-estimation of the accuracy of our knowledge and judgements

26
Q

information framing

A

ex. 75% lean versus 25% fat

ex. free for credit card, versus discount for cash

27
Q

consciousness

A

required for complex and novel tasks

28
Q

subconscious cues

A

influence out impressions without coming into consciousness

29
Q

alertness/arousal

A

our ability to remain attention to what’s going on; controlled by brainstem and reticular formation (RAS)

30
Q

PSG

A

polysomnography - multimodal technique to measure processes during sleep

EEG - electrical impulses in brain
EMG - muscle
EOG - oculogram

31
Q

alpha waves

A

small amplitude, high frequency; as somebody prepares for sleep

HIGH consciousness

32
Q

sleep stages

A

alpha waves (drowsy) -> non-REM sleep (Stage 1) -> K-complexes and sleep spindles (Stage 2) -> Stage 3/4 (delta waves - slow wave), lowest level of consciousness -> REM sleep

33
Q

Stage 1 sleep

A

theta waves (low to moderate intensity, intermediate frequency 3-7 hertz) - slow rolling eye movements and moderate muscular activity

has fleeting thoughts and less responsive to stimuli

LIGHT consciousness

34
Q

Stage 2 (sleep)

A

K-complexes and sleep spindles

K-complex (0.5 second, large and slow), a single wave amongst theta waves

sleep spindles - bursts of waves 12-14 Hz moderately intense (last 0.5-1.5 seconds)

NO eye movement, moderate muscular activity

Increased relaxation

INTERMEDIATE consciousness

35
Q

Stage 3/4 (sleep)

A

transition into slow wave sleep

delta waves (high amplitude, low frequency)

No eye movement, moderate muscle activity

Heart rate slows, digestion slows, growth hormones are secreted

36
Q

REM sleep

A

paradoxical sleep

bursts of eye movements

similar to beta waves (similar to awake) - low intensity, more jagged than beta waves

Low (almost no) skeletal movement - bursts and twitches

Dreaming occurs here.

High level of consciousness

37
Q

sleep overview

A

babies need more sleep (16 hours)

deep sleep (stage 3/4) are longest early in the night

sleep cycle is 90 minutes (includes periods of non-REM and REM sleep)

REM periods increase as night goes on

38
Q

sleep regulation

A

nerve from retina to suprachiasmatic nucleus (SCN) in the hypothalamus, which signals other parts of the brain, regulating body temperature and lease of hormones

SCN is the internal clock - cortisol is released in the morning

39
Q

Melatonin

A

produced in the pineal gland. controlled by SCN, controls sleepiness

light causes drop in Melatonin

40
Q

body temperature…

A

drops toward the end of the day and during sleep

41
Q

REM rebound

A

increase in REM sleep if it is missed

42
Q

manifest content

A

plotline of dream, Freud, filled with unconscious drives and wishes that are difficult to express

inner conflict

43
Q

sleeping benefits

A

improve learning and problem-solving

e.g. rats dreaming of solving a maze, which helped performance

44
Q

purpose of dreams

A

byproduct of brain activation during REM sleep

provide a template for consciousness, to practice consciousness-development

45
Q

narcolepsy

A

bursts of sleepiness lasting less than 5 minutes, related to a lack of OREXIN (hypocretin)

46
Q

dyssomnia

A

insomnia, narcolepsy, sleep apnea

47
Q

parasomnia

A

abnormal behaviors during sleep

  • somnambulism (sleepwalking) occurs during SLOW WAVE sleep, first third of night
  • genetics for somnambulism
  • night terrors: stage 3
48
Q

hypnotism

A

focus on what is being said by the hypnotist, relax

recall memories versus constructing false memories through imagination

cannot force people to do extreme things

useful for pain relief; headaches, asthma, and stress-related skin disorders

Dissociation theory: extreme form of divided consciousness; the subject is on autopilot and hypnotist takes over executive control

Social Influence theory: people adopt a role

49
Q

meditation

A

training of attention

manage pain, stress, and anxiety

mindfulness-based stress reduction (MBSR) - medically reduce stress - increased alpha and theta waves

50
Q

three classes of psychoactive drugs

A
  1. depressants, 2. stimulants, 3. hallucinogens
51
Q

depressants

A

alcohol, barbiturates (tranquilizers), opiates

slow neural activity

alcohol suppresses REM sleep, reduced short-term memory and less restful sleep

alcohol overdose depresses the respiratory control centers in medulla to the point breathing stops

52
Q

alcohol effects

A

stimulates GABA (anxiety-reduction) and dopamine (minor euphoria)

prolonged alcohol intake reduces the brain

depress the sympathetic NS

53
Q

barbiturates

A

depress the sympathetic NS

sleep aid

dangerous in combination with alcohol, prone to overdose

opiates mimic neurotransmitters endorphin

54
Q

stimulants

A

caffeine, nicotine, cocaine, amphetamines

increase release of NT, reducing reuptake of NT, both

increased energy, respiratory rate, heart rate, pupil dilation

cocaine releases dopamine, serotonin, and norepineprhine

55
Q

MDMA

A

serotonin and dopamine, mild hallucinogen, causes a reduction serotonin level that may cause depressed mood

56
Q

LSD

A

vivid colors and imagery; separation from one’s body; euphoria to panic

57
Q

THC

A

stimulates cannabinoid receptors in the brain; relaxes and disinhibits like alcohol. amplifies sensory perceptions like colors, sounds, tastes, and smells

impairs motor skills, reaction time, judgement

Can help with nausea and pain

58
Q

psychological dependence

A

using a drug in response to painful situation, depression, anxiety, or trauma

i.e. using alcohol at a party

59
Q

physical dependence

A

evidenced by withdrawal. a physical and painful experience alleviated only by the drug

caffeine addiction has withdrawals

60
Q

addiction

A

biologically-based. nucleus accumbens “pleasure center”
