DefinitionTermFirst Letters
the process of receiving stimulus energies from the environmentS
the process of transforming psysical energy into electrochemical energyT
the brain's process of organizing and interpreting sensory information to give it meaningP
processing that begins with sensory receptors registering environmental information and sending it to the brain for analysis and interpretationB-U P
processing of perceptual information that starts out with cognitive processing at the higher levels of the brainT-D P
specialized cells that detect stimulus information and transmit it to sensory (afferent) nerves and the brainS R
the field that studies specialized links between the physical properties of stimuli and a person's experience of themP
the minimum amount of stimulus energy that a person can detectA T
irrevelant and competing stimuliN
the detection of information below the level of conscious awarenessS P
the smallest difference in stimulation required to discriminate one stimulus from another 50 percent of the tme; also called just noticeable differenceD T
the principle that two stimuli must differ by a constant minimum percentage (rather than a constant amount) to be perceived as differentW L
the theory about perception that focuses on decision making about stimuli in the presence of uncertainty; detection depends on a variety of factors besides the physical intensity oS D T
focusing on a specific aspect of experience while ignoring othersS A
a predisposition, or readiness, to perceive something in a particular wayP S
a change in the responsiveness of the sensory system based on the average level of surrounding informationS A
the light-sensitive surface in the back of the eye that records what we see and converts it to neural impulses for processing in the brainR
the receptors in the retina that are sensitive to light but are not very useful for color visionR
the receptors in the retina that process information about colorC
neurons in the brain's visual system that respond to particular features of a stimulusF D
the simultaneous distribution of information across different neural pathwaysP P
the bringing together and integration of what is processed through different pathways or cellsB
theory stating that color perception is produced by three types of receptors (cone cells in the retina) that are particularly sensitive to different, but overlapping, ranges of wavT T
theory stating that cells in the visual system respond to red-green and blue-yellow colors; a given cell might be excited by red and inhibited by green, whereas another might be exO-P T
DefinitionTermFirst Letters
principle by which individuals organize the perceptual field into stimuli that stand out (figure) and those that are left over (background, or ground)F-G R
school of psychology emphasizing that people naturally organize their perceptions according to certain patternsG P
the ability to perceive objects three-dimensionallyD P
depth cues that are based on the combination of the images on the left and right eyes and the way the two eyes work togetherB C
depth cues that are available from the image in either eyeM C
the perception that a stationary object is movingA M
recognition that objects are constant and unchanging, even though sensory input about them is changingP C
a discrepancy between reality and the perceptual representation of it.V I
consists of pinna and external auditory canalO E
consists of the eardrum, hammer, anvil, and stirrupM E
consists of the oval window, cochlea, and basilar membraneI E
the theory of hearing that states that each frequency produces vibrations at a particular spot on the basilar membraneP T
theory stating that perception of a sound's frequency depends on how often the auditory nerve firesF T
modification of frequency theory stating that a cluster of nerve cells can fire neural impulses in rapid succession, producing a volley of impulsesV P
nerve that carries neural impulses to the brain's auditory areasA N
sensory receptors, located under the skin, that respond to changes in temperature at or near the skin and provide input to keep the body's temperature at 98.6 degrees FahrenheitT
the sensation that warns us that damage to our bodies is occuringP
theory stating that the spinal column contains a neural gate that can be opened (allowing the perception of pain) or closed (blocking the perception of pain)G-C T o P
bumps on the tongue that contain taste buds, the receptors for tasteP
a sheet of receptor cells for smell that lines the roof of the nasal cavityO E
senses that provide information about movement, posture, and orientationK S
senses that provide information about balance and movementV S
structure in the inner ear containing the sensory receptors that detect head motionS C
