Week 3 cont..

Question 1

Cat/Ct scan

Answer 1

Computerized axial tomography

Question 2

PET

Answer 2

Position Emission Tomography

Question 2

MRI

Answer 2

Magnetic Resonance imaging
- picture/ spacial resolution

Question 3

FMRI

Answer 3

Functional MRI
- video
- temporal resolution

Question 4

spacial resolution

Answer 4

how clear us the image
- high = very clear
poor= blurry

Question 5

Temporal resolution

Answer 5

capturing brain activity while its happening
- timing

Question 6

Psychological measures

Answer 6

EEG ( Electroencephalogram)
- many electros attached to skull to measure electric activity
- gives great temporal information
- non ivasive

Question 7

ERP

Answer 7

(Event related potential)
timed with specific stimulu i.e reaction when light flashes

Question 8

FFA ( Fusiform Face Area)

Answer 8

cluster of neurons that process faces on underside of temporal lobe

Question 9

prosopagnosia

Answer 9

Brain damage where you cant process faces

Question 10

Distributed processing

Answer 10

sees a picture - visual stimuli- memory use - recognition- figuring name

Question 11

neural network: perception of photo

Answer 11

eg. one photo some see smile others see a letter
- visual processing is the same, pattern of recognition changes perception
- experience changes outcome

Question 12

Perception / saccade

Answer 12

interpretation of sensation (transition from sensation to perception)
Saccade: small fast eye movements

Question 13

visual sensory register

Answer 13

stores sensory information ( storage unit for memory)
-accuracy
large capacity
short duration

Question 14

Sensory trace

Answer 14

how we perceive things as continuous

Question 15

visual sensory register- Accuracy

Answer 15

if accurate then purely sensory, pre-categorical
- category should interfere

Question 16

pattern recognition

Answer 16

process where meaning is derived by perception
- inherit ability to detect patterns
- music pattern of sounds

Question 17

Bottom up processing

Answer 17

data driven
- recognition of object based on only object itself

Question 18

top down processing

Answer 18

conceptually driven
- expectations, memories, context, surroundings can help recognition

Question 19

Agnosia

Answer 19

Trouble recognizing objects
A = without
Gnosia = knowledge

Question 20

Apperceptive agnosia

Answer 20

trouble putting object together
- cant name it since they have not seen it

Question 21

Associative agnosia

Answer 21

know it but cant name it
- dont know what is associated with the object

Question 22

PR theories template

Answer 22

• compares stimulus to template: takes too long to go through all templates
• have to keep searching memory ( pre-processing)
