Eye Can See Clearly Now
A hole in the retina which contains no photoreceptors.
What is the blind spot?
The five basic tastes.
What are sweet, sour, salty, bitter, and umami?
Something that arouses activity in something else.
What is a stimulus?
The sense of hearing.
What is audition?
The process by which the brain interprets sensory information, turning it into meaningful representations of the external world.
What is perception?
People with normal color vision who can discern all colors of the visible spectrum
What are trichromats?
Smell and taste are this type of sense.
The absolute smallest amount of a given stimulus a person can sense.
What is absolute threshold?
A form of deafness usually involving damage to the middle ear, in which there is a loss of conduction of sound vibrations through the ear.
A process whereby the brain assembles specific features of shapes to form patterns that we can compare with stored images we have seen before.
What is bottom-up processing?
Photoreceptors that are sensitive only to the intensity of light, and photoreceptors that are sensitive only to color.
What are rods and cones?
It carries impulses from olfactory receptors in the nose to the brain.
What is the olfactory nerve.
What is sensory adaptation?
_______ bend in response to vibrations of the basilar membrane, triggering neural impulses that travel through the auditory nerve to the brain.
What are hair-cell receptors?
A collection of perceptual rules people use to group objects according to certain organizational principles.
What are Gestalt laws of grouping?
Specialized neurons in the visual cortex that respond only to particular features of visual stimuli, such as horizontal or vertical lines.
What are feature detectors?
The awareness of the position and movement of parts of the body, AND a sense in the inner ear which monitors the posture and movement of the body in space.
What are kinesthesia and the vestibular sense?
An explanation for the conditions under which a stimulus will be detected, involving the intensity of the stimulus, the level of background stimulation, and biological and psychological characteristics of the perceiver.
What is signal detection theory?
The maximum displacement of air molecules, leading to pressure fluctuations, AND the rate of movement of molecules set into motion by a vibrating object (also Hz).
What are amplitude and frequency?
An explanation for the Muller-Lyer illusion, which proposes that it is more prevalent in carpentered, right-angled cultural settings.
What is the carpentered-world hypothesis?
A theory of color vision which explains how colors are processed after they leave the retina, and due to opposing processes involving red-green and blue-yellow color receptors and black-white brightness receptors.
What is opponent-process theory?
A theory which proposes that we perceive pain because a neural gate in the spinal cord opens to allow pain messages to reach the brain and closes to shut them out.
What is the gate-control theory of pain?
The principle that the amount of change in a stimulus needed to detect a difference is given by a constant of the original stimulus
What is Weber's law?
A theory which suggests that our perception of pitch depends on the frequency of vibration of the basilar membrane and the volley of neural impulses transmitted to the brain via the auditory nerve.
What is frequency theory?
Relative size, interposition, relative clarity, texture gradient, linear perspective, and shadowing.
What are monocular cues?
