Consciousness

Question 1

consciousness definition

Answer 1

not a synonym for intelligence (computers/robots are intelligent)

Question 2

The unconscious

Answer 2

sigmund freud

• awareness of face = activation of face processing areas of brain
• awareness of house - activation of place processing areas of brain
  + measure what people are aware of at certain times; what about non-attended stimuli

Question 3

global workplace

Answer 3

activity fluctuates spontaneously in binocular rivalry in response to experience (info competes to be broadcast) … want to be part of unitary ACCESS CONSCIOUSNESS

Question 4

Phenomenological consciousness

Answer 4

reps. that don’t reach access consciousness (not reported but still influence behavior, ie. there’s a dog)

– im[licit priming (“good boy”, “bad boy”)

Question 5

Blindsight

Answer 5

damage to visual cortex - blind spot in corresponding part of visual field, yet still “aware” of object (ie. woman w carbon monoxide poisoning = “blind”)

Question 6

2 visual systems

Answer 6

both process info about structure of objects & spacial locations but use info in diff. ways

VENTRAL STREAM: perceptual representations of enduring characteristics (identification & relationships) - conscious of it

DORSAL STREAM: moment-to-moment info about location & disposition of objects; mediates visual control of skilled actions directed at those objects (NOt conscious of it)

maze running; singing

awaken to name more likely than other sounds (greater activation in mid-temporal gyrus & orbitofrontal cortex)

Question 8

Coma

NULL EFFECTS OF CONSCIOUSNESS

some parts of brain unaffected by our consciousness processes; ie. visual illusions - look at some aspect & cannot not pay attention to it
- consciousness not talking to perceptive machinery

Question 9

phantom limb

Answer 9

illusion of both arms present,during pain in missing limb, open & close hands - hand “permanently clenched” feeling - eliminate pain by means of visual illusion that remaps cortical areas associated w/limb

Question 10
