- a created by Edward Hering; alternative theory used to explain after images; suggest that the retina contains three pairs color receptors or cones-yellow-blue, red-green, black-white; pairs work in opposition (thalamus)
- b the light-sensitive inner lining of the back of the eyeball; contains receptor cells (rods/cones)
- c The distance from the peak of one light or sound wave to the peak of the next. Electromagnetic wavelengths vary from longer/red, shorter/blue
- d a device for converting sounds into electrical signals and stimulating the auditory nerve by electrodes threaded into the cochlea
- e The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs.
5 Multiple choice questions
- Diminished sensitivity as a consequence of constant stimulation.
- visual receptor cell; located in retina; respond to varying degrees of light and dark; responsible for night vision and peripheral vision
- Ernst Weber; the principle that accounts for how one notices the difference threshold for any change must be proportional
- snail-shaped structure in the inner ear; contains fluid that vibrate; attach the oval window and basilar membrane
- in perception, the ability to adjust to an idea or mind set
5 True/False questions
Depth perception → the mental process of sorting, identifying, and arranging raw sensory data into meaningful patterns
signal detection theory → In hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch.
middle ear → snail-shaped structure in the inner ear; contains fluid that vibrate; attach the oval window and basilar membrane
basilar membrane → a device for converting sounds into electrical signals and stimulating the auditory nerve by electrodes threaded into the cochlea
transparent part of the eye behind the iris; focuses light on the retina (accommodation); change shape to focus on objects;-if object is closed, muscles attach to the land contract to make lens around,-if object is far away, the muscles pull to flatten the lens
