Q

Fixation

A
  1. When we get stuck on certain problems
  2. Occurs due to:
    2a. Mental set: unnecessary constraint that is imposed on problem solving due to attempting to solve problems based on strategies that were employed in the past and worked
    3b. Functional fixedness: tendency to only consider objects in terms of their usual functions

Q

Insight vs incubation

A
  1. Insight: When we keep trying to solve a problem and the solution finally clicks
  2. Insight can occur due to incubation: When we stop working on a problem but our brains work on them subconsciously

Q

States of consciousness

A
  1. Alertness: awake (beta waves on EEG)
  2. Daydreaming: mind wanders, more relaxed (alpha waves)
  3. Drowsiness: just before sleep/after waking up (theta waves)
  4. Sleep
    4a. Light sleep (1, 2): theta waves
    4b. Seep sleep (3,4): delta
19
Q

4 stages of sleep

A
  1. N1/Stage 1: both alpha and theta waves, people experience hypnagogic hallucinations, hypnic jerks
  2. N1/Stage 2: more theta waves, K complexes, sleep spindles
  3. N3/Stage 3: Slow wave sleep (SWS), delta waves, sleepwalk/talk occurs here
  4. REM: dreaming occurs here, mix of alpha and beta here
    4a. Important for memory consolidation
20
Q

Circadian rhythm

A
  1. Loosely tied to s 24 hour cycle
  2. Hormones
    2a. Melatonin from pineal gland: sleep
    2b. Cortisol from adrenal cortex: awake
21
Q

Sigmund Freuds theory of dreams

A
  1. Dreams result from our unsonscious thoughts, desires
    1a. Manifest: what actually occurs in dream
    1b. Latent: hidden meaning in dream
22
Q

Jungs theory of dreams

A
  1. Content is related to persons unconscious thoughts/desires but it focuses on early memories and professional interpretation
23
Q

Activation synthesis theory

A
  1. dreams from brain stem and synthesized from cortex
24
Q

Threat stimulation theory

A
  1. Dreams are evolutionary advantageous as they stimulate stressful interactions
25
Q

Sleep disorders

A
  1. Dyssomnia
    1a. Insomnia: can’t sleep
    1b. Narcolepsy: can’t stay awake
    1c. Sleep apnea: can’t breath in sleep where obstructive (OSA) is caused by soft tissue in airway constricting airway & central (CSA) is when its a mindset: both are treated using a CPAP
    1d. Hypoventilation syndrome: treated with CPAP and its when a person loses the ability to get rid of co2 in the blood
  2. Parasomnia
    2a. Sleepwalking /sleeptalking which both occur during N3
26
Q

Induced states of consciousness

A
  1. Hypnosis: relaxed, more susceptible to suggestions
    1a. Social influence theory: hypnotism doesn’t induce altered state of consciousness but describes people conforming to behaviour thats expected by them
    1b. Dissociation theory: says hypnosis is an altered state of consciousness that should be separated from normal conscious experience
  2. Meditation: training mind in attention and awareness
27
Q

    1a. alcohol: bind GABA receptors in CNS, allow Cl- , inhibits

    1c. barbiturates: bind GABA receptors in CNS, allow Cl- , inhibits
28
Q
