Q

A
  1. intentionality: quality of being directed towards an object
  2. unity: resistance to division/ ability to integrate info from all of the body’s senses into one coherent whole
  3. selectivity: capacity to include some objects but not others/brain makes decisions about what info to include or exclude

Q

What are the different levels of consciousness?

A
  • minimal: low-level kind of sensory awareness & responsiveness that occurs when mind inputs sensations may output behavior
  • full: you know and are able to report your mental state

Q

What is ironic processes of mental control?

Q

What are dual-process theories?

A

suggest that we have 2 different systems in our brains for processing info:
1. dedicated to fast, automatic and unconscious processing (System 1); helps efficiently navigate your daily life
2. dedicated to slow, effortful and conscious processing (System 2); uses info and inputs from S1 to help guide future behavior

26
Q

What is the naturally occurring 24-hour cycle?

A

circadian rhythm

27
Q

What changes in electrical activity occur in the brain during the circadian cycle?

A
  • during waking: alternating between high frequency activity (beta waves) during alertness and lower-frequency activity (alpha waves) during relaxation
28
Q

When do the largest changes in EEG occur?

A
  • during sleep there are 5 stages
29
Q

What are the 5 sleep stages?

A

Stage 1: Theta waves
Stage 2: sleep spindles and K complexes (short bursts of activity)
Stage 3 & 4: delta waves
Stage 5: sawtooth waves

30
Q

What is the 5th stage of sleep called?

A

REM: stage of sleep characterized by rapid eye movements and high level of brain activity

31
Q

What is the glymphatic system?

A
  • system in the brain that eliminates potentially neurotoxic waste products and distributes necessary compounds through brain such as glucose, lipids and amino acids
  • operates mainly during sleep
32
Q

What is insomnia?

A
  • difficulty in falling asleep or staying asleep
  • self induced insomnia: lifestyle choices
  • secondary insomnia: response to depression, anxiety, other conditions
  • primary insomnia: no obvious causal factors
33
Q

What’s sleep apnea?

A
  • disorder in which the person stops breathing for brief period while asleep
  • involuntary obstruction of breathing passage
34
Q

What is somnambulism/sleep walking?

A
  • occurs when a person arises and walks around while asleep
  • usually during slow wave sleep
35
Q

What is narcolepsy?

A
  • disorder in which sudden sleep attacks occur in middle of waking activities
  • intrusion of sleep into wakefulness & accompanied by unrelenting excessive sleepiness and uncontrollable sleep attacks (30 sec-30min)
  • genetic basis
36
Q

What is sleep paralysis?

A
  • the experience of waking up unable to move
  • occurs when waking from REM sleep but before you have regained motor control
37
Q

38
Q

What are the 5 characteristics of dream consciousness?

A
  1. We intensely feel emotion
  2. Dream thought is illogical: continuities don’t apply
  3. Sensation is fully formed and meaningful
  4. Dreaming occurs with uncritical acceptance: as if events are normal
  5. We have difficulty remembering the dream after it’s over
39
Q

What is Freud’s theory of dreams?

A
  • dreams are confusing and obscure because the dynamic unconscious creates them precisely to be confusing

40
Q

What is Freud’s manifest content of a dream?

A

A dream’s apparent topic or superficial meaning is a smoke screen for its latent content > dream’s true underlying meaning

41
Q

What is the action synthesis model? (Hobson, McCarley)

A

theory that dreams are produced when the brain attempts to make sense of random neural activity that occurs during sleep

42
Q

What is the difference between Freud’s theory and activation synthesis theory?

A

Freud: dreams begin with meaning
AST: dreams begin randomly, but meaning can be added as the mind lends interpretations in process of dreaming

A

Activated: motor cortex, visual association areas, amygdala, brainstem
Deactivated: prefrontal cortex

46
Q

What are psychoactive drugs?

A
  • chemicals that influence consciousness or behavior by altering the brain’s chemical message system
  • agonists: increase activity of a neurotransmitter
  • antagonists: decreasing activity of a NT
47
Q

What is drug use initially motivated by?

A

positive reinforcement: increase in the likelihood of a behavior following the presentation of a reward

48
Q

Q

What are 2 theories explaining the variable effects of alcohol on people?

A

  2. alcohol myopia: condition that results when alcohol hampers attention, leading people to respond in simple ways to complex situations
52
Q

What is a balanced placebo design?

A

study design in which design in which behavior is observed following the presence/ absence of an actual stimulus and also following the presence/absence of a placebo stimulus

53
Q

What are stimulants?

A
  • substances that excite the central nervous system, heightening arousal and activity levels

54
Q

What are narcotics/opiates?

A
  • highly addictive drugs derived from opium that relieve pain
