Sensation

5. a coiled, bony fluid-filled tube in the inner ear through which sound waves trigger nerve impulses
6. the system for sensing the position and movement of individual body parts
9. point on the cochlea where sound is moved from the ossicles to the cochlea
10. theory that absolute threshold is influenced by our experience and education
15. color is created by a combination of three colors, red, blue and green
16. translate smells for the brain
19. 25% of the population that has an abundance of taste receptors
21. muscle that controls the amount of light that enters the pupil
22. using the sensory receptors to detect the lines, angles, and colors that form an image
24. theory that the spinal cord contains a neurological "gate" that blocks pain signals or allows them to pass on to the brain; the spinal cord nerve fibers conduct most of the pain signals
27. cells that convert information to neural impulses for the brain
29. focusing on one stimulus to the exclusion of other things
31. clear film that protects the eye

1. a process where we detect physical energy from the environment and encode it as neural signals
2. the ability to block or tune out a constant stimulus
3. the number of complete wavelengths that pass a point in a given time
4. the sense of body movement and position, including the sense of balance
7. detect black, white or gray
8. the point in the eye where there are no rods and cones because of the attachment to the optic nerve
9. color is processed by opponent pairs; one color processing blocks the processing of another
11. the minimum difference a person can detect between any two stimuli half the time
12. to process information by constructing perceptions drawing on our experience and expectations
13. three bones in the middle ear that transfer sound waves to the cochlea
14. transfers information from the air to the ossicles
17. lies on the back of the eye and translates information for the optic nerve
18. structure that changes shape to focus images on the retina
20. the minimum stimulation necessary to detect a particular light, sound, pressure, taste, or ordor 50% of the time
23. a tone's experienced highness or lowness {depends on frequency}
25. detect well-lit light or daylight conditions
26. carries information to the brain. Its made up of axons
28. the retina's area of focus, where the cones cluster
30. 25% of the population that has a small number of taste receptors
