5 True/False Questions
convergence → The innermost part of the ear, containing the cochlea, semicircular canals, and vestibular sacs.
opponent-process theory → The theory that opposing retinal processes (red-green Christmas, yellow-blue Michigan, white-black) enable color vision.
subliminal perception → Ability to see objects in three dimension although the image that strike the retina are two-dimensional; allows us to judge distance
Young-Helmholtz trichromatic theory → The spinal cord contains a "gate" that blocks pain signals or allows them to pass on to the brain. It's opened by the activity of pain signals traveling up small nerve fibers and is closed by activity in large fibers or information coming from the brain.
Color constancy → The number of complete wavelengths that pass a point in a given time (for example, per second).
