Perception

Question 1

what is perception

Answer 1

conscious experience that results from stimulation of the senses
combines outside world(visual stimuli) and inner world (prior knowledge)
recognize, organize, interpret info

Question 2

what is an example of perception

Answer 2

reading, seeing the letters, using info of shapes and combination of letters to make words, then sentences

Question 3

what is form/shape perception

Answer 3

sensory processes transform, organize info provided by sensory receptors
stimuli compared w/ other info in memory
we gr into categories (properties, features, context)

Question 4

Bottom-up processing (data driven)

Answer 4

info from stimulus reaches sensory receptors, triggers pattern recognition process
combination of simple features allows global recognition
two lines = t, brain puts info together

Question 5

top-down processing (concept driven)

Answer 5

prior knowledge of how the world is organized helps identify forms
expectations = recognize shapes more easily (draw from what we know to interpret new info)
stroop effect: reading vs saying colour of the ink
hike: saw car, noise of branches cracking could be them walking down

Question 6

what are the 5 principles of pattern recognition

Answer 6

1. recognize quickly and accurately
2. recognize and classify unfamiliar objects
3. recognize shapes from different angles
4. accurately identify shapes when partly hidden
5. recognize with ease and automaticity

Question 7

what are the pattern recognition theories

Answer 7

1. template matching
2. prototype
3. recognition by components
4. Feature detection

Question 8

what is the face recognition task of gender identification

Answer 8

male vs female faces
participants can guess gender w/ gender cues 96%
21% errors when upside down

Question 9

what was the face recognition task with the house and its conclusions

Answer 9

Present face, then house, then parts of both and need to guess which they have seen before
recognize faces globally (relationship btw the features is most imp in face recognition)
can recognize house more isolated parts

Question 10

what is face blindness

Answer 10

ppl lose the ability to recognize faces
can identify male/female, young/old but not familiarity

Question 11

what is the perception pathway

Answer 11

the what pathway
from visual cortex to temporal lobe

Question 12

what is the action pathway

Answer 12

the where/how pathway
from visual cortex to parietal lobe

Question 13

what 2 pathways are needed to take action like lifting a coffee cup

Answer 13

perception and action pathway

Question 14

how are illusions used to alter perceptions

Answer 14

curved lines on dresses: silhouette
curtains to the ceiling: taller room
contour makeup: bone structure
mirror in small areas

Question 15

how is human perception superior to machine intelligence

Answer 15

faster
have ability to judge more about the context, environment
can induce/infer more and easily
accumulate SO MUCH info since we are born
perceive obj when it is hidden
recognize contours when blurred
can move around objects to perceive different angles

Question 16

how can prior knowledge help us view the world accurately sometimes, and inaccurately at others

Answer 16

• steam = hot
• clear = nothing, but it was a glass door
