The Visual Sense: Sight

Question 1

Retina

Answer 1

A specialized sheet of nerve cells in the back of the eye containing the sensory receptors for vision

Question 2

Transduction

Answer 2

the process that involves converting stimulus energy into neural impulses that be interpreted in the brain

Question 3

rods

Answer 3

(more rods than cones) rods are responsible for detecting light and dark

Question 4

cones

Answer 4

(there are fewer cones than rods) cones are for detecting colours

Question 5

Photoreceptors

Answer 5

sensory receptor cells located in the retina (cones and rods)

Question 6

Optic Nerve

Answer 6

Carries visual information

Question 7

blind spot

Answer 7

completely lacking in rods and cones

Question 8

Light enters the __
Light passes through the __
Lightwave pass-through the __
The light waves are projected into the __

Answer 8

cornea
pupil
lens
retina

Question 9

Young_ Helmoltz Trichromatic Theory (trio)

Answer 9

The cones in the retina carry three different sensors for colour; red, green, blue

Question 10

Opponent Process theory

Answer 10

colours work together to inhibit one another (you cannot see yellowish-blue or red-green)

Question 11

Myopia

Answer 11

you can see near objects but cannot see far objects as clear

Question 12

hyperopia

Answer 12

you can see far objects but cannot see near objects as clear

Question 13

monochromatic

Answer 13

unable to see any colours

Question 14

strabismus

Answer 14

when eyes are not aligned and two different images are sent to the brain

Question 15

amblyopia

Answer 15

when the weaker eye becomes blind

Question 16

“what” pathways

Answer 16

Identifies objects- the what pathway travels from the occipital cortex to the temporal cortex

Question 17

“where” pathways

Answer 17

Identifies location- the where pathway travels from the occipital cortex to the parietal cortex

Question 18

Visual agnosia

Answer 18

damage to the “what” pathway; cannot identify objects

Question 19

Hemi-neglect

Answer 19

damage to the “where” pathway; people neglect one side of their vision (e.g. eat food from one side of the plate)

Question 20

Gestalt psychology

Answer 20

believe that perception helps us add meaning to visual information by attempting to organize information into groups (the whole is more than the sum of its parts)

Question 21

retinal disparity

Answer 21

the left eye sees the object on the left and the right eye sees the flat surface

Question 22

vestibular system

Answer 22

the sensory system that tells us where we are in space

Question 23

kinesthetic system

Answer 23

knowing the position of the various parts of our body and the receptors are located in the muscles and joints

Question 24

prosopagnosia

Answer 24

sees faces but do not remember them very well
