Q

What is the Moore and Egeth study of visual illusions and inattentional blindess?

Q

When do stimuli “capture” attention and why?

A

It’s meaningful: your own name captures your attention

You’re expecting it: if you watch bear/gorilla video again you’ll be more likely to see it

It’s interesting/complex: a happy vs. simple geometric shapes

Q

What are het two phenomena’s about preconscious processing?

A
  1. We sometimes have difficulty raising items from preconscious to conscious. (top of the tongue phenomenon)
  2. Stimuli that we are not aware of can still affect us (effects of subliminal priming and blindsight)

Q

What is blindsight?

A

Blindsight is another way in which stimuli we are not aware of can affect our behavior.

Person cannot consciously see a certain portion of their visual field but still behave in some instances as if they can see it

Being aware of perceiving something is distinguishable from just perceiving something

Q

What is the individual feature processing (Trisman’s feature-integration theory)?

A

It is done in parallel. Simultaneous processing is done on the whole display and if feature is present – we detect it.

Q

What is conjunctive searching (Treisman’s feature-integration theory)

A

Requires attention to the integration or combination of the features. Attention to particular combination of features must be done sequentially to detect presence of a certain combination.

Q

What is an example of conjunctive search?

A

28
Q

What is the prediction of Treisman’s Theory: illusory conjunctions?

A

You can be illusory conjunctions under some conditions. Show red square and green circle and subjects report seeing red circle.

29
Q

What is parallel processing?

A

It is when you are processing multiple aspects of a stimulus or problem simultaneously.

30
Q

What is consciousness?

A

The subjective awareness of ourselves and our environment. All the sensations, perceptions, memories, and feelings you are aware of in any instant.

30
Q

What is sequential processing?

A

Requires focused attention on one thing at a time.

30
Q

What is sequential processing best for?

A

Solving new problems.

31
Q

Consciousness is not an all-or-nothing phenomenon–it exists on a _______

A

continuum

32
Q

What is waking consciousness?

A

Normal, clear, organized, alert awareness. Focused attention

33
Q

What is Altered State of Consciousness (ASC)?

A

Awareness that is distinctly different from waking consciousness like hypnosis, drugs, sensory deprivation, medication, hallucinations, comas, hibernation

34
Q

What is the circadian rhythm?

A

24 hour biological clock - periodic fluctuations in physiological functioning (body temp, blood pressure, alertness wake/sleep, hormone levels, immune system)

35
Q

What is the Suprachiasmatic Nucleus (SCN)?

A

It’s a part of the hypothalamus and is involved in maintaining circadian rhythms.

36
Q

What is the general process of the Suprachiasmatic nucleus (SCN)?

A

Receives direct input from the eyes - monitoring light levels

Large lesions of hypothalamus disrupt circadian cycles of activity in rats.

Lesions specific to SCN disrupt periodicity of sleep/wake cycle

SCN displays circadian cycles of electrical, metabolic, and biochemical activity

37
Q

What are the different brain waves?

A

Beta waves, Alpha Waves, Delta Waves

38
Q

What are Alpha waves?

A

Larger, slower waves associated with relaxation and just before falling asleep

39
Q

What are delta waves?

A

Very large and slow waves associated with a move to deeper sleep and further loss of consciousness

40
Q

What are beta waves?

A

Small fast waves associated with alertness and being awake

41
Q

What kind of waves do we have when we wake up?

A

Alpha (calm, relaxed) or Beta (more focused and active) Waves

42
Q

What is stage 1 of sleep?

A

NREM-1

Smaller, irregular waves produced in light sleep (people may or may not say they were asleep)

43
Q

What is the hypnic jerk?

A

Relax muscle twitch throughout body that may occur in stage 1

44
Q

What is stage 2 of sleep?

A

NREM 2

Deeper sleep; sleep spindles (bursts of distinctive brain-wave activity) appear

45
Q

What is stage 3 of sleep?

A

NREM 3

Deeper sleep; delta waves appear; very large and slow. Then we get deepest level of normal sleep; almost purely delta waves

46
Q

What is stage 4 of sleep?

A

REM. Associated with dreaming; sleep is very light. Body is very still during REM sleep

47
Q

How does REM sleep change with age?

A

Young adults spend more time in deep sleep than older adults

48
Q

What is Freud’s wish-fulfillment?

A

Dreams preserve sleep and provide a “psychic safety valve” –expressing otherwise unacceptable feelings; contain manifest (remembered) content and a deeper layer of latent content (a hidden meaning)

49
Q

What is the information - processing theory?

A

Dreams help us sort out the day’s events and consolidate our memories

50
Q

What is the physiological function dream theory?

A

Regular brain stimulation from REM sleep may help develop and preserve neural pathways

51
Q

What is the neural activation dream theory?

A

REM sleep triggers neural activity that evokes random visual memories, which our sleeping brain weaves into stories

52
Q

What is the cognitive development dream theory?

A

Dream content reflects dreamers’ level of cognitive development –their knowledge and understanding. Dreams stimulate our lives, including worst-case scenarios

53
Q

Biological and psychological explanations of behavior are ______, not _______.

A

partners; competitors

54
Q

What is manifest content (Freud)?

A

Remembered story line

55
Q

What is latent content (Freud)?

A

Underlying meaning

56
Q

What are the general ideas of Freud’s “The Interpretation of Dreams”?

A

Wish fulfillment
Discharge otherwise unacceptable feelings

57
Q

What are the four dream processes (mental filters) that hide true purposes of dreams?

A

Condensation, Displacement, Symbolization, and Secondary Elaboration

58
Q

What is condensation (Freud)?

A

Combining several people, objects, or events into a single dream image

59
Q

What is displacement (freud)?

A

Directing emotions or actions toward safe or unimportant dream images

60
Q

What is symbolization (freud)?

A

Nonliteral expression of dream content

61
Q

What is secondary elaboration (freud)?

A

Making a dream more logical and complete while remembering it

62
Q

What functions have theorists proposed for dreams?

A
  1. To satisfy our own wishes
  2. To file away memories
  3. to develop and preserve neural pathways
  4. to make sense of neural static
  5. to reflect cognitive development
63
Q

What is Perls dream interpretation?

A

Most dreams are a special message about what is missing in our lives, what we avoid doing, or feelings that we need to re-own

64
Q

What are some theories as to why we sleep?

A
  1. Adaptive functions: sleep may have played a protective role in human evolution by keeping people safe during potentially dangerous periods. Also save energy/calories
  2. Restorative and Cognitive Functions.
  3. Restore immune system
  4. Remove toxins - free radicals
  5. Sleep also helps restore and repair damaged neurons
  6. REM and NREM2 sleep help strengthen neural connections that build enduring memories
  7. Sleep promotes creative problem solving the next day
  8. During deep sleep, the pituitary gland secretes a growth hormone necessary for muscle development
