vision

Question 1

mperception

Answer 1

interpreting the information through five senses

info sent to the brain through sensation

results in interpreting

psychological significance - experiences and ideologies

Question 2

sensation

Answer 2

process of receiving info

stimuli obtained from sensory organs

results in perception

biological procedure

Question 3

Electromagnetic spectrum -EMS

Answer 3

there is a tiny part put of all this that is visible to the human eye

Question 4

wavelenght

Answer 4

shorter - more energy
longer - less energy

nano meters

Question 5

visible spectrum

Answer 5

what the human eye sees from the EMS

350-750 NANO meters

we see colors

Question 6

umwelt

Answer 6

unique way that each animal experiences the world around!!!!!!

Question 7

transduction

Answer 7

converts one form of energy to another form

eyes - lights in the eye and then turned to action potential

Question 8

what captures the light

Answer 8

the eye

Question 9

the eye

Answer 9

sclera - white part
cornea - actual lens

the focusing power is by cornea

iris - the color part of the eye
pupil - is the small darker circle
lens - behind pupil
retina - part of the CNS,
fovea
optic nerve -

Question 10

pupil

Answer 10

is the small darker circle

narrows when bright light, small focus

wide for more light when there are dim lights

Question 11

lens

Answer 11

thickens when we have to focus on nearby objects

focus on distance objects it flattens

as we get older, we need glasses cuz lens works less

Question 12

Retina

Answer 12

part of the CNS at the development stage then it gets pushed out

transduction takes place - converts light into electro signals

last stop the light goes through then it goes to the thalamus through the optic nerve

Question 13

photo receptors (nerve cell)

Answer 13

cones - detect color and details

rods - sensitive to light but not color

signals are collected in the ganglia cells and they form the optic nerve

Question 14

colour perception

Answer 14

color - the brain interpreting the wavelength that we see

Question 15

trichromatic theroty

Answer 15

the eye has three types of receptor and each is responsible to a specific part of the spectrum

L - RED long wave
s - blue short wave
n - green medium wave

Question 16

how do we see million colors with only three cones

Answer 16

mixing colors to make others,

for example - white light goes through all three cones

Question 17

opponent process theory

Answer 17

looking at a color for too long, the red cones becoming fatigue and so we see green after staring at red

Question 18

myopia

Answer 18

myopia
distant ones are blurry
near they see clearly

when the eyeball is too long
or the cornea is bending light too strongly

image resting before retina rather on it

Question 19

hyperopia

Answer 19

distant is clear while near ones are blurry

eyeball is too short
or the cornea does not refract enough

image focus behind retina rather on it

Question 20

lazy eye

Answer 20

eyes going diff directions

treatable at childhood

Question 21

retinal disorder - color blind

Answer 21

red - green deficiency
effects 8% of men

blue yellow deficiency

Question 22

retinal - glaucoma

Answer 22

increase pressure around the eye and damage to the optic nerve

lose peripheral then central

significant deficiency in vision

transmission issue

Question 23

retinal - macular degeneration

Answer 23

lose central vision then peripheral

Question 24

cortical - abnosia

Answer 24

see an object but cannot recognize what it is,

know it but cant name it
