Sensation & Perception

1. a theory that retinas contain RGB color receptors
3. process of our eye lens changing shape to focus objects on the retina
7. a theory linking the pitch we hear w/ the place where the cochlea membrane is stimulated
8. process of converting one form of energy into one usable by your brain
9. a theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone
14. a kind of hearing loss caused by damage to the cochlea's receptor cells or auditory nerves
15. system for sensing the position & movement of body parts
16. below one's absolute threshold for conscious awareness
17. activation of associations that predispose one's perception, memory, or response

2. a way of constructing perception guided by expectations & experience
4. theory that opposing retinal processes enable color vision
5. perceived color determined by the wavelength of light
6. a kind of hearing loss caused by damage to the mechanical system conducting soundwaves to the cochlea
10. an organized whole
11. a type of phenomenon in which illusory movement is perceived when at least 2 adjacent lights blink on & off
12. a theory that the spinal cord has a neurological "gate" for pain signals
