sensation is bottom up
top down processing changes how features are perceived because it changes the way you see a picture etc. 
sensory adaptation- when senses get use to something so you no longer hear/see/feel it anymore
intentional blindness-cant perceive something when attention isn't there
change blindness-magicians do this, environment changes 
precentage change - difference threshold weber's law JND
absolute threshold - what you need to be able to precieve something 50% of the time smallest amount 
difference thrshold - is the difference between that
weather - top down processes

brighter the color the more brighter it has to get to be able to notice the difference
absolute threshold-finding the faintest amout of something
sub-threshold-learning something without knowing
difference threshold-telling the difference between things]]> 2016-10-12 12:32:00 UTC https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/130096750 October 13 kaitlynnsta5797 https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/130403768 I can understand the parts and the path of vision]]> 2016-10-13 12:30:01 UTC https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/130403768 path kaitlynnsta5797 https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/130403914 corena - protects eye, where light enters
pupil- ajustible opening controls how much light is let in
iris- color part of eye protects from damage and muscle contracts to let light in.
lens - transparent part of eye inside the pupil that focuses light onto retina (upside down) by changing curvature
Accommodation lens shape changes according o distance (round close, flat far
retina inner lining on the back of the eyeball that contains receptor cells sensitive to light
blind spot- point whee the optic nerve leaves the eye; no vision receptors here 
Fovea- line of centrl focus hold only cones
Optic Nerve- carries visual info to the occupital lobe but 1st goes to the thalamus
optic chiasm- spot whee nerves cross each other left to tight tight to left
Later geniculate nucleus- area in thalamus that interprets images where it is flipped right side up

afterimages you see opposite color]]> 2016-10-14 12:32:10 UTC https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/130708975 kaitlynnsta5797 https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/130710524 partialor totla inalbilty to perceive hues 
monochromats black and white
dichromats red green or yellow blue
trichromats norma color vision 
helmhotz theory doesnt explain color blindess inbolves 2 colors pairs not 1 single cone. he said should be you vant see green or yellow red
2 opponent process theory hering
three kinds of cones that work in pairs red and green blue and yellow black and white
paired with opposites if one is stimulated the is inhibited 
both theories are correct

relative size- assumption that 2 objects are similar size 1 closer has larger retinal image 
relative clarity- aka aerial perspective perception tha Hazy objects are farthr away than sharp objects
Texture gradient- coarse distinct texture is closer than finer indistinct texture
relative height- objects higher in field of vision appear father away (vertical dimensions appear longer than horizontal dimensions
relative motion- movement of self cause stable item to appear to move nearest object appears to move faster
linear perspective- parallel lines appear to converge in distance people over estimate trains distance
light and shadow aka shadowing- nearby objects reflect more light into eyes simmer objects appear farther away]]> 2016-10-17 12:53:17 UTC https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/131110202 monocular cue kaitlynnsta5797 https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/131110234 2016-10-17 12:53:23 UTC https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/131110234 binocular cue kaitlynnsta5797 https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/131114730 cues that require both eyes

Place Theory- suggested by helmhotz, able to hear diffrent pitches of sounds based on the placement of the neural activity on the basilar membrane in the cochela
2. Frequency Theory- vibrations trigger neural impulses to the brain at the same rate as a sound wave, lower frequency=fewer neual impulses, higher frequencies= larger amount of neural impulses
3.Volley principle- neural cells can alternate firing and there by acheive combined fequency for very adverage pitch]]> 2016-10-18 12:44:07 UTC https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/131437312 October  kaitlynnsta5797 https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/133287538 Prepare for the FRQ and multiple choice test]]> 2016-10-26 12:28:06 UTC https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/133287538 October 26 kaitlynnsta5797 https://padlet.com/kaitlynnsta5797/2ea0pw0gxf1/wish/133288764 What are arguments for and against receiving a cochlear implant?
for: help her hear  and speak live a normal possibly more happy life
against: has to drill very far into skull, loosing culture
