Gestalt- as a whole "form"

Figure groud- organized info into a figure against a grounds

2. Proximity- group nearby figures together (Muller- Lyer illusion)

3.similaryity- group similar figures together

4. Continuity- See smooth, continuous pattern
5. Connectedness- when linked, we see spots, lines or areas as a single unit
6.depth perception- 2 dimensions fall on retina; perceive as 3D we estimate distance -visual cliff- eleanor gibson and richard walk
(6 months understand depth)
7.Visual constancy- perceiving objects as unchanging despite changes in retinal images (color,shape,size,location, brightness)
Color constancy- Perception of familiar objects as having consistent colors, even if changing illumination (apple color)
Size constancy- Despite distance, object doesnt change size (general idea of size)
shape constanct- see same shape angle its at
Brightness and color
Monocular- (1 eye)
-Interposition- 1 object blocks view of another so often referred to superpostition
Relative size- assumption that 2 objects are similar size 1 closer has larger retinal image
Relative clarity-/ Aerial perspective- perception that hazy objects are farthe3r away that sharp objects
Texture Gradient- coarse, distinct texture is closer than finer, insidtinct texture
Relative height- objects higher in field of vision appear farther away (vertical dimensions appear longer than horizontal dimenstions
Relative motion/ motion parallex- 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 (people overestimate train's distance)
Light and shadow/ shadowing- Nearby objects reflect more light into eyes ( dimmer objects appear farther away)
Binocular cues - 2 eyes
Retinal disparity- difference between sights/ views of 2 eyes 
Convergence- cue for perceiving depth; eyes converge inward towards objects
Stereoscopic vision- combo ]]> 2016-10-17 15:17:55 UTC https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131178323 ashleymur5145 https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131178966 2016-10-17 15:19:26 UTC https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131178966 ashleymur5145 https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131179003 2016-10-17 15:19:30 UTC https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131179003 ashleymur5145 https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131179075 2016-10-17 15:19:40 UTC https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131179075 ashleymur5145 https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131179535 2016-10-17 15:20:48 UTC https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131179535 ashleymur5145 https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131179819 2016-10-17 15:21:23 UTC https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131179819 ashleymur5145 https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131507324 Conductive deafness
-problems of conducting sound wave to cochlea
-ear drum puncture/ bones cant vibrate 
-can be repaired with hearing aids
Hearing problems
Sensorineural hearing loss
-nerve deafness (hair cells)
-cause-loud noises age or genetics
-cochlea implants may be helpful 
Mc Gurk effect- same sound different view or video
Tritone paradox- different preference of hearing  (high low or low high)
Shepard tone illusion- brain doesnt notice drop and it sounds like its getting higher but its the same repetative sound
Hairs causes culclia in the baslar membrane 
Place theory- Origionally suggested by helmholts by georg von  
-Ability to hear different pitches; higher frequency
Frequency theory - vibratiobn triggers neural impulses to brain at same rate as sound wave (Brain reads pitch from frequency)
Lower frequency- fewer neural impulses
Higher frequency- Larger amount of neural impulses  explains low 
Volley principle- Neural cells can alternate firing and thereby acheive combines frequency for very average pitch]]> 2016-10-18 15:13:49 UTC https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/131507324 ashleymur5145 https://padlet.com/ashleymur5145/3fwpppqjfpcl/wish/132729826 I can understand other senses

The chemical senses (olfactory)

Receptor cells- olfactory/ mucous membrane (epithlium)
Top of nasal cavity
 
Olfactory- Receptors are clogged if you are sick and cant smell
Receptor cellls sends info to olfactory bulb to limlib system ) amygdala then to hippocampus)
 olfactory strongly correlated with memory  due to connection with limbic system

Gustation(taste)- different from flavor- sensory  interaction 
smell+ taste/ texture 
taste buds- papillae receptors cells for taste characteristic pattern to taste  (5 types - sour sweet bitter ...)

Skin- cutaneous sensations -pressure temp and pain

Some spots are especially sensitive to certain stimuli (not specific) pressure only receptors brain is most sensitive to unexpecte stimulation
-certian areas of body have more concentrated tactile nerve endings than others

Kinesthesis- sense of body parts and positions with pns 
Vestibular sacs- what make you dizzy
monitor head position and movement 
Semicircular calals -connects cannals with cochlea fluid (spin=dizzy)
Pain - No one specific receptor or stimulus individual differences.. ---athletes more tolerant mindset can effect reactions
-cultures
-cognition
-physiological - female stronger tollerance 

Gate control theory- Neurological gate in the spinal cord controls the transmission of pain to the brain 
Small nf open (pain) / large nf close (other senses close of pain)
neurotransmitter- with endocrine 

How people respond to pain (daniel kahneman) Phantom limb- misinterpretation -demonstration= candle technique vs. walking over the coals 

Touch- when touch warm and cold feel hot Skin sensations- pressure only skin sensation with identifiable receptors- warmth,cold, pain
