- Color constancy
- optic nerve
- difference threshold
- a Conversion of one form of energy into another. In sensation, the transforming of stimulus energies into neural impulses.
- b Just Noticeable Difference (JND); the smallest change in stimulation that you can detect 50% of the time; differs from one person to the other (and from moment to moment); tells us the flexibility of sensory systems
- c sense of muscle movement, posture, and strain on muscles/joints; provides information on speed and direction of movement; works with vestibular sense

- e bundle of axons from ganglion cells that carries messages from the eye to the brain
5 Multiple Choice Questions

5 True/False Questions
binocular cues → visual messages/cues that require two eyes (retinal disparity, convergence)
sensory adaptation → the raw data of experience; sensory stimulation; example are eyes only register light energy and ears only register wave energy
habituation → decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner
David Hubel - Torsten Wiesel → discovered feature detector groups of neurons in the visual cortex that respond to different types of visual images
perceptual accommodation → In vision, the ability to adjust to an artificially displaced or even inverted visual field
