what part uses elementary elements of the brain that creates meaning

sensation

perception

transduction

transcription

Answer 1

sensation

Question 2

define perception

Answer 2

that translation of stimuli to create sensory understanding of the world. By translating sensory information to electrochemical language for the brain.

figure and ground

Answer 3

figure and ground

Question 9

what is the retina

Answer 9

thin layer of tissue that has photoreceptors

Question 10

what is the cornea

Answer 10

transparent covering of eye, 80% of focusing on visual image

Question 11

what is the pupil

Answer 11

hole in eye that expands and contracts allowing light to enter

Question 12

in situations where you eyes are in bright light would your pupils dilate (become bigger) or contract (become smaller)

Answer 12

contract

Question 13

what part of the eye is the muscle bands of the pupil attached to?

Answer 13

the iris

Question 14

what is the purpose of the iris

Answer 14

give eye its colour and contracts and restricts

Question 15

your lens is located behind your pupil what is it focusing the light on to

Answer 15

the retina

Question 16

define accomadation

Answer 16

the lens ability to change shape to refract light onto the retina

Question 17

what is myopia

Answer 17

nearsightedness can see object close but not far away.

image forms in front of retina b/c eye is elongated

Question 18

what is hyperopia

Answer 18

far sightedness can see objects far away but not close up

image forms behind retina b/c eye is smaller

Question 19

what are phtotreceptors

Answer 19

photosensitive cells

cones and rods

Question 20

what is the difference between rods and cones

Answer 20

rods are more responsive to low light while cones are responsive to bright light, colour, and acuity

Question 21

the fovea is located at the center of the retina what is there?

only rods

only cons

rods and cons

blind spot

Answer 21

cons only

Question 22

there are 126 million photosensitive cells how many are cones? rods?

26 million cones, 100 million rods

120 million cones, 6 million rods

100 million cones. 26 million rods

6 million cones, 120 million rods

Answer 22

6 million cones, 120 million rods

Question 23

At night which cells are most likely more responsive?

rods or cones

Answer 23

rods

Question 24

What happens if you are outside in bright light but walk into a dark room

Answer 24

cones become sensitive (as sensitive as possible after 8 minutes)

rod increase sensitivity (for another 20 minutes)

Question 25

why would an image of a retinal image be presented upside down?

Answer 25

because during refraction the lens inverts the image but b/c of understanding of world image is presented us as right side up

Question 26

color is the perception of _____ sensory output wavelength rods reds, yellows, and blues

Answer 26

wavelength

Question 27

rank the from lowest to highest wave length greens reds blues

Answer 27

blues (450 nm) greens (530 nm) red (~670 nm)

Question 28

what is the trichromatic theory

Answer 28

color information is identified by comparing activation of different cones in retina

Question 29

which con is activated when seeing the color green? red? blue?

Answer 29

Medium wavelength cones long wavelength cones short wavelength cones

Question 30

photo capture of dogs running one appear to be closer as it blocks the view of the other dorg. what depth cue is this? relative height occlusion medium wavelengths cones

Answer 30

occlusion

Question 31

objects closer to the horizon will appear farther away and the greater the distance between the horizon the closer the object looks. what depth cue is this? Relative size relative height relative horizon

Answer 31

relative height

Question 32

what is relative size?

Answer 32

when two objects are of equal size, the one that is farther away will take up a smaller portion of the retina

Question 33

what is ames room

Answer 33

illusion in which person looks giant in room due to depth of room

Question 34

what is perspective convergenace

Answer 34

As parallel lines move away from us into the distance, they seem to converge or come closer together

Question 35

if we see a photo of a lighthouse in the distance what depth cue can explain why we assume the lighthouse is far and not just tiny

Answer 35

familiar size

Question 36

when does atmospheric perspective occur?

Answer 36

when objects appear hazy with blue tint because of distance (mountains)
