module 5.2

Question 1

what is sent from our sensory organs

Answer 1

optic nerves: brightness, colour, forms
auditory nerves: loudness, pitch, timbre

Question 2

what is perception

Answer 2

translate into what we hear and see
object ID/recognition- what is it?
Depth- where is it?
Movement: what is it doing

Question 3

how do we organize information from our sensory system

Answer 3

sensation and perception

Question 4

what is gestatists

Answer 4

1920-30
the whole is more than the sum of its part
-we organize pieces of info into wholes

Question 5

what is form perception

Answer 5

important perceptual habits that allow us to perceive unified forms from stimuli
-figure and ground
- grouping (proximity, similarity, continuity, connectedness, closure)

Question 6

what is motion perceptions?

Answer 6

we can build perception of motion from quickly flashing scenes

Question 7

Depth perception

Answer 7

• Monocular cues
  – Accomodation
  – Motion parallax
  – Pictorial
• Binocular cues
  – Convergence
  – Retinal disparity

Question 8

example of binocular convergence

Answer 8

brings finger closer to face make you cross eyed

Question 9

Binocular: Retinal disparity
example

Answer 9

See a slightly different
view with each eye
* Hold your finger in front
of you
* Close one eye, then the
other

Question 10

monocular accomadtion example

Answer 10

lens is curved for close vision and flat when distance

Question 11

what is motion parallax

Answer 11

Nearby objects seem to move faster than
more distant ones
– Driving, paddling, running

Question 12

what is Pictorial: Interposition (apple pear)

Answer 12

If one object partially blocks
our view of another, we
perceive it as closer.
* Most effective with familiar
objects
* Gestalt closure also
influences this

Question 13

what is Pictorial: Relative size (little human big human)

Answer 13

If we assume two
objects are similar in
size, the one that cases
the smaller retinal
image is perceived as
being more distant

Question 14

Pictorial: Linear perspective

Answer 14

train tracks parallel the more they converge the farther they are percieved

Question 15

Pictorial: Texture

Answer 15

Closer objects have more texture visible than distant
objects.

Question 16

Pictorial: Shading

Answer 16

If the light hits the
bottom of the object, we
perceive it as receding
from us. If it hits the top,
we perceive it as
approaching us.

Question 17

Perceptual organization beyond vision (languag)

Answer 17

Foreign vs. familiar language
– sounds faster
– harder to parse into figure/ground (words)
* True orally and visually
