cue that relies on the use of both eyes

slightly different view of the world that each eye receives

point where we cannot respond to visual information in that portion of the visual field

system in which perceptions are built from sensory input

organizing our perceptions into complete objects rather than as a series of parts

fluid-filled, snail-shaped structure that contains the sensory receptor cells of the auditory system

electronic device that consists of a microphone, a speech processor, and an electrode array to directly stimulate the auditory nerve to transmit information to the brain

failure in the vibration of the eardrum and/or movement of the ossicles

specialized photoreceptor that works best in bright light conditions and detects color

deafness from birth

genetic disorder that results in the inability to experience pain

transparent covering over the eye

partial or complete inability to hear

logarithmic unit of sound intensity

ability to perceive depth

all the electromagnetic radiation that occurs in our environment

segmenting our visual world into figure and ground

small indentation in the retina that contains cones

number of waves that pass a given point in a given time period

field of psychology based on the idea that the whole is different from the sum of its parts

(also, continuity) we are more likely to perceive continuous, smooth flowing lines

auditory receptor cell of the inner ear

cycles per second; measure of frequency

failure to notice something that is completely visible because of a lack of attention

middle ear ossicle; also known as the anvil

signal that some type of tissue damage has occurred

sound coming from one side of the body is more intense at the closest ear because of the attenuation of the sound wave as it passes through the head

small difference in the time at which a given sound wave arrives at each ear

colored portion of the eye

difference in stimuli required to detect a difference between the stimuli

perception of the body’s movement through space

curved, transparent structure that provides additional focus for light entering the eye

perceive depth in an image when two parallel lines seem to converge

middle ear ossicle; also known as the hammer

touch receptor that responds to pressure and lower frequency vibrations

touch receptor that responds to light touch

one-eared cue to localize sound

cue that requires only one eye

results in a degeneration of inner ear structures that can lead to hearing loss, tinnitus, vertigo, and an increase in pressure within the inner ear

pain from damage to neurons of either the peripheral or central nervous system

sensory signal indicating potential harm and maybe pain

bulb-like structure at the tip of the frontal lobe, where the olfactory nerves begin

sensory cell for the olfactory system

color is coded in opponent pairs: black-white, yellow-blue, and red-green

X-shaped structure that sits just below the brain’s ventral surface; represents the merging of the optic nerves from the two eyes and the separation of information from the two sides of the visual field to the opposite side of the brain

carries visual information from the retina to the brain

touch receptor that detects transient pressure and higher frequency vibrations
