|
three theories of pitch perception |
place theory frequency theory volley theory
|
|
|
place theory |
the pitch is determined by which place along the cochelas basilar membrane is most activated
lose high pitches with age |
|
|
frequency theory |
pitch is determined by the frequency with which the basilar membrane vibrates |
|
|
volley theory |
neurons work in groups and alternate firing, thus achieving a combined frequency corresponding to the frequency of the sound wave |

perceptual constancy |
the tendency to percieve pbjects as relatively stable |
|
|
size constancy |
percieve objects as stable in size despite changes in their size of their retinal image when they are viewed from different distances |
|
|
shape constanct |
perviece an object as the same way no matter what angle it is viewed |
|
|
induced movement |
illusion that a stationary object is moving caused by seeing a moving object nearby
ex: looks like your car is moving when its the cars nearby actually moving... :0 |
