Across
- 1. the system for sensing body orientation and balance, which is located in the semicircular canals of the inner ear
- 3. the point at which the optic nerve travels through the retina to exit the eye; the lack of rods and cones at this point creates a small blind spot
- 4. the receptor cells for hearing; these are located in the cochlea and are responsible for changing sound vibrations into neural impulses
- 5. Specialized cells in every sensory system of the body that can turn other kinds of energy into action potentials (neural impulses) that the brain can process.
- 8. a sound's highness or lowness, which depends on the frequency of the sound wave
- 9. the system for sensing the position and movement of individual body parts
- 10. the process of organizing and interpreting incoming sensory information
- 14. The major organ of hearing; a snail-shaped, bony, fluid-filled structure in the inner ear where sound waves are changed to neural impulses
- 16. threshold (just noticeable difference) the minimum amount of difference needed to detect that two stimuli are not the same
- 19. diminished sensitivity to constant and unchanging stimulation
- 20. a ring of muscle tissue that forms the colored portion of the eye and regulates the size of the pupil
- 21. threshold the minimum amount of stimulation needed to detect a particular stimulus
- 22. processing information processing that draws on expectations and experiences to interpret incoming sensory information
- 23. The light-sensitive surface at the back of the eyeball
- 25. nerve the nerve that carries visual information from the eye to the occipital lobes of the brain
- 26. focusing conscious awareness on a particular stimulus to the exclusion of others
Down
- 2. a theory that predicts how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise)
- 6. the adjustable opening in the center of the iris, which controls the amount of light entering the eye
- 7. A theory of color vision that says color is processed by cones organized in opponent pairs (red-green, yellow-blue, and black-white); light that stimulates one half of the pair inhibits the other half.
- 11. A theory of color vision that says cones are sensitive to red, green, or blue light- the three colors that combine to create millions of color combinations
- 12. visual receptor cells located in the retina that can detect only black, white, and gray
- 13. the transparent structure behind the pupil that changes shape to help focus images on the retina
- 14. the clear, curved bulge on the front of the eye that bends light rays to begin focusing them
- 15. information processing that analyzes the raw stimuli entering through the many sensory systems
- 17. visual receptor cells located in the retina that can detect sharp details and color
- 18. the process by which our sensory systems (eyes, ears, and other sensory organs) and the nervous system receive stimuli from our environment
- 24. erve the nerve that carries sound information from the ears to the temporal lobes of the brain
