Psych - Sensory Perception

Question 1

Answer 1

Iris

Question 2

Visual cues allow us to perceptually organize by:

Answer 2

• Depth
• Form
• Motion
• Constancy

Question 3

Binocular cues are most important for perceiving ___

Answer 3

Depth

Question 4

What are the two types of binocular cues?

Answer 4

• Retinal disparity
• Convergence

Question 5

Retinal disparity, a type of ___, is responsible for ___

Answer 5

binocular cue, perceiving distance

Question 6

Convergence, a type of ___, is responsible for perceiving ___, which is determined by ___

Answer 6

binocular cue, depth, how much the eyes turn inward

Question 7

What is the purpose of monocular cues?

Answer 7

gives a sense of shape/form and distance of an object

Question 8

What are 4 characteristics of form provided by monocular cues?

Answer 8

• Relative Size
• Interposition (Overlap)
• Relative Height
• Shading and Contour

Question 9

Monocular cues give a sense of

Answer 9

• Form
• Motion
• Constancy

Question 10

Relative size

Answer 10

• Monocular cue (form)
• Bigger objects are perceived to be closer to the viewer

Question 11

Interposition

Answer 11

• Monocular cue (form)
• If one object blocks view of another, it is perceived as being closer to the viewer

Question 12

Relative Height

Answer 12

• Monocular cue (form)
• If an object is higher than another, it is perceived as being further away from the viewer

Question 13

Shading/Contour

Answer 13

• Monocular cue (form)
• Uses light and shading to perceive form, depth, and contours (ex. closer objects seem closer because they reflect more light)

Question 14

Motion Parallax

Answer 14

• Monocular cue (motion)
• Closer objects appear to move faster than those further away

Question 15

Constancy

Answer 15

• Monocular cue
• Image of an object does not change even if the image on the retina does

Question 16

Size Constancy

Answer 16

• Monocular cue (constancy)
• an object that is closer appears bigger than one further away even though they are known to be the same size

Question 17

Shape Constancy

Answer 17

• Monocular cue (constancy)
• awareness that an object is not necessarily changing shape even though it appears to be changing shape/the shape of the image on the retina changes (ex. opening a door)

Question 18

Color Constancy

Answer 18

• Monocular cue (constancy)
• Perception of color as the same despite changes in lighting that make colors appear different

Question 19

The ___ contracts during hearing adaptation in response to ____, but requires ___

Answer 19

inner ear, higher noise levels, time (ex. occurs during a prolonged concert but not a gunshot, since the gunshot is instantaneous)

Question 20

Name the four lobes of the brain

Answer 20

• Frontal
• Parietal
• Temporal
• Occipital

Question 21

Where in the brain does sensory processing occur?

Answer 21

Projection areas

Question 22

What is the clear, watery fluid that fills the space between the cornea and lens?

Answer 22

Aqueous humor

Question 23

What is the function of the aqueous humor?

Answer 23

Provides pressure to maintain the shape of the eyeball

Question 24

What produces the aqueous humor?

Answer 24

The ciliary body

Question 25

What is the purpose of the canal of Schlemm?

Answer 25

Canal through which the aqueous humor drains

Question 26

What would likely result from a defect in the ciliary body?

Answer 26

• issues with production of the aqueous humor
• no aqueous humor production = issues with pressure necessary to maintain shape of eyeball

Question 27

What is the eye’s outermost layer?

Answer 27

Cornea
