45 Cards in this Set

  • Front
  • Back
the experience of semsory stimulation
the process of creating meaningful patterns from raw sensory information
the least amount of energy that can be detected as a stimulation
absolute sensory threshold
an adjustment of the senses to the level of stimulation a person is receiving
the smallest change in stimulation that can be detected
the visual system
the transparent protective coating over the front part of the eye
a small opening in the iris thru which light enters the eye
the colored part of the eye
the transparent part of th eye inside the pupil that focusses light on the retina
the lining of the eye containing receptor cells that are sensitive to light
...are sensitive only to a fraction of the electromagnetic energy spectrum
receptor cells
receptor cells in the retina responsible for night vision and perception of brightness
receptor cells in the retina responible for color vision
neurons that have only one axon and one dendrite; in the eye, these neurons connect the receptor ont the retina to the ganglion cells
bipolar cells
the ability to distinguish fine details visually
visual acuity
the bundle of axons of ganglion cells that carry neural messages from each eye to the brain
optic nerve
the place on the retina where the axons of all the ganglion cells leave the eye and where there are no receptors
blind spot
theory that pitch is determined by the location of greatest vibration on the basiliar membrane
place theory
theory that pitch is determined by the frequency with which hair cells in the cochlea fire
frequency theory
refinement of the frequency theory; suggests that receptors in the ear fire in sequence with group responding one after another so that the complete pattern of foring corresponds to the frequency of the sound waves
volley principle
small bumps on the tongue that contain taste buds
structures on the tongue that contain the receptor cells for taste
taste buds
senses of muscle movement, posture, and strain on muscles and joints
kinesthetic senses
receptors that sense muscle stretch and contraction
stretch receptors
receptors that sense the movement of the tendons, which connect the muscle to the bone
golgi tendon organs
the senses of equilibrium and body position in space
vestibular senses
entity percieved to stand apart from the background
backgound against which a figure appears
a tendency to perceive objects as stable and unchanging despite changes in sensory stimulation
perceptual constancies
observer characteristics are...
perception of distance and depth includes...
-monocular cues
-binocular cues
perception of movement includes...
-autokinetic illusion
-stroboscopic motion
-phi phenomenon
visual illusions include...
-physical illusions
-perceptual illusions
the aspect of color that corresponds to names such as red, green and blue
the vividness or richness of a hue
the nearness of a color to white as opposed to black
the process of mixing light of different wavelengths to create new hues
additive color mixing
the process of mixing apigments, each of which absorbs some wavelengths and reflects others
subtractive color mixing
the theory of color vision that holds that all color perception derives from three different color receptors in the retina
trichromatic color theory
partial or total inability to perceive hues
theory of color vsion that holds that three sets of color receptors(yellow-blue, red-green, and black-white) respond to determine the color your experience
opponent-process theory
the theory that a "neurological gate" in the spinal cord controls the transmission of pain messages to the brain
gate control theory
neurons that connect the bipolar cells in the eyes to the brain
ganglion cells
the point near the base of the brain where some fibers in the optic nerve from each eye cross to the other side of the brain
optic chaism
