priming 
-Perceptual set - your environment influencing your mind
-Perception- to figure out what the sense are

2) bottom up processing
3)  top down processing changes our inferences 
1) Sensation: Sandwich word
Perception: Cambridge University reading Test 
In-attentional blindness- what you are concentrated on  
Change blindness- changing the environment 
1) percent change hold= difference threshold

JND- just noticeable difference- the minimum difference a person can detect between any two stimuli  50% of the time aka Weber's law
- Constant fraction/ proportion of original stimulus
Approximate thresholds
- Taste- 1 gram of salt in 500 liters of H20
Subliminal 
Signal detection theory- ]]> 2016-10-12 12:24:43 UTC https://padlet.com/louishar6355/9j4258j2nxv2/wish/130095216 louishar6355 https://padlet.com/louishar6355/9j4258j2nxv2/wish/130402558 I can understand the Parts and the path of vision

Optic Chiasm- spot where nerves cross each other( left to rght/ right to left)
Lateral geniculate Nucleus- area in Thalamus that interprets image

From cornea aqueous pupil lens retina fovea

Receptor cells( rods and cones) receptors cells responsible for vision 20:1 rods out number, Bipolar cells,- specialized neuron connect to rods and cones ganglion cells- axons of these cells made of optifc nerve and sends infor ro thalamus, optic nerve, brain

Two ganglion cells 
magnocellur cells detect motion
Parvocellur cells detect color and what it is 

Acuity- ability to distinguish fine details, sharpness

Intensity- brightness

Wave lengths determine hue or colors

transduction light mass pass through the layers of the retina

virteious humor allows the lens to change shaoe]]> 2016-10-13 12:25:21 UTC https://padlet.com/louishar6355/9j4258j2nxv2/wish/130402558 louishar6355 https://padlet.com/louishar6355/9j4258j2nxv2/wish/130710165 I can learn color theories and visual cues Transduction
Parallel processing
Feature Detectors 
Wave length- the distance from one wave peak to another
High Frequency- Short frequency bluish colors high pitched sounds
Low frequency long wavelength reddish colors and low pitched sounds

RED long BLUE Violet Short
Amplitude- the height of the wave length
Large amplitude tall wavelength, bright colors and loud sounds
Small amplitude short wave lengths dull colors soft sounds
Young- Helmholz Trichromatic theory
Each one is maximally sensitive to one of three colors 
combined stimulation of these cones cause other colors by mixing light waves

Afterimages- when you stare at 1 or 2 colors, cones become saturated, then when you look at a white piece of paper you see the opposite colors due to saturation of cones

color blindness- partial or total inablity to percieve hues
Momochromats black and white
Dichromats r/g y/b
Trichromats normal color vision
color blindness involves 2 colors pairs not single cones. 

Opponent process theory 
three kinds of cones of all work in pairs
r/g
b/y
b/w
Paired with opposites; if one is stimulated the other is inhibited 

surrounding context if an item is viewed with other colors then the color of the object changes

-color constancy- perception of familiar objects as having consistent colors even if changing illumination
-Figure ground- we organize information into a figure seen against a ground
- Proximity- group nearby figures together 
- Similarity- group similar  figures together
- Continuity- see smooth, continuous patterns
-Connectedness- when linked, we see spots, lines or areas as a single unit
-Depth perception- 2 dimensions fall on retina; perceive as 3D
-Visual cliff- test of depth perception, infants and toddlers (by 6 months)
-Visual constancy= perceiving objects as unchanging despite changes in retinal images
color shape size location brightness
- Size constancy- despite distance objects don,t change size
-shape constancy- see same shape despite angle it is at
Monocular cues- interposition= ( 1 object blocks view of another so)
Relative size= assumption that 2 objects are similar size 1 closer has retinal images
Relative Clarity= Perception that hazy objects are farther away than sharp objects
Texture gradient= coarse, distinct texture is closer than finer, indistinct texture
Relative height= objects higher in field of vision appear farther away
Relative motion= movement of self causes stable items to appear to move, nearest object appears to move faster
- linear perspective= parallel lines appear to converge in distance ( (Ponzo illusion)
Light and shadow shadowing- nearby objects reflect more light into eyes
muller lyer illusion the line experiment
Binocular cues- cues that require both eyes
Retinal desparity= difference between sight/ views of 2 eyes
Convergence- cue for perceiving depth; Eyes converge inward towards object

Assumption- closer object gets larger
Stroboscopic movement= motion pictures
Phi Phenomenon= illusion of lights
Autokinetic illusion= perceived motion created by single stationary object
Sound localizations
monaural cue- louder sound means closer sound
Binaural cues= stereophobic- stero: multi directional audio perspective]]> 2016-10-17 13:07:09 UTC https://padlet.com/louishar6355/9j4258j2nxv2/wish/131116865 louishar6355 https://padlet.com/louishar6355/9j4258j2nxv2/wish/131430587 I can listen to the ear video

Pinna- refer the outer ear
Ear canal- our auditory canal which enables us to hear sound through the air
Ear drum- which vibrates to let us hear the sound
Hammer, Anvil, and the stirup are three tiny bones that help vibrate the eardrum which are called the ossicles
The stirrup also vibrates the outer window to allow to open
The outer window transfers air to liquid
Inside the cochlea is the basilar membrane- tiny Little hair cells- these are what vibrate in the liquid form 
Auditory nerve
Vestibular organ is what makes up balance
Eustacian tube- connects ears to your throat
Organ of corti- cochlea to auditory nerve to thalamus then to temporal lobe
Place theory-  Ability to hear different pitches of  sounds to due the location of nueron activity on basilar membrane on the cochlea
Frequency theory- vibration triggers neural impulses to the brain at same rate as sound wave
Lower frequencies=  lower neural impuleses
Volley thoery- neural cells can alternate firing]]> 2016-10-18 12:25:55 UTC https://padlet.com/louishar6355/9j4258j2nxv2/wish/131430587 louishar6355 https://padlet.com/louishar6355/9j4258j2nxv2/wish/132662972 Olfactory- not to thalamus 
Receptor cells sends info to olfactory bulb limbic system 
Gustation- different from flavor= Sensory interaction
smell+taste/ texture
Taste buds- receptors cells for taste 
5 tastes- salty, sour, bitter, umami, 
skin senses- pressure, temperature,
brain is most sensitive to unexpected stimulation 
Kinesthesis- sense of body parts and positions
Vestibular sense- monitors head position and movement(balance)
Semicircular canals (Balance)
vesitbular sacs (Dizzy) connects canals with cochlea ( fluid)
Gate Control theory- neurological gate in the spinal cord controls the transmission of pain to the brain 
Small nf open/ large nf close 
Endorphin associated to pain
Morphine drug helps reduce pain
Phantom limb- misinterpretation
Skin sensation
pressure warmth cold pain ]]> 2016-10-24 12:26:42 UTC https://padlet.com/louishar6355/9j4258j2nxv2/wish/132662972 louishar6355 https://padlet.com/louishar6355/9j4258j2nxv2/wish/132968759 - I can understand other senses

I will study by looking at my padlet 
- They argue because Deaf people have their own culture
- The deaf parents are scared of losing their daughter to the hearing world
- she was progressively able to talk 
- She was able to blend in school and was treated normally, however, she had a hard time keeping up in class 
- Able to try out for volleyball ]]> 2016-10-26 12:25:51 UTC https://padlet.com/louishar6355/9j4258j2nxv2/wish/133286945
