unit 3 Flashcards
a lab device for testing the depth perception of infants
visual cliff
diminished sensitivity as a consequence of constant stimulation
sensory adaptation
conversion of one form of energy into another; changing energy into a neural impulse.
transduction
a coiled, fluid-filled part of the inner ear through which sound waves trigger nerve impulses
cochlea.
receptors in the retina that detect black and white
rods
hearing loss due to the damage of the mechanical system (parts) that sense sound waves
conductive hearing loss
the focusing of conscious awareness on a particular stimulus as in the contain party effect
selective attention
the idea of opposite retinal processes that enable color vision (red-green, blue-yellow etc.)
opponent-process theory
the belief that the retina contains three different color receptors
young-hemholtz thrichromatic theory
hearing loss due to the damage in the cochlea
sensorineural hearing loss
the ability to see objects in three dimensions
depth perception
sense of body movement and position including balance
vestibular sense
analysis that begins with the sense receptors and worksup to the brain’s sensory information.
bottom-up processing
a mental predisposition to perceive one thing or another
perceptual set
the system for sensing the position and movement of individual body parts
kinesthesis.
the central focal point in the retina where cones are heavily concentrated is known as what
the fovea
the opponent-process theory is most useful for explaining
afterimages
which is the correct order of the structures through which light passes after entering the eye
cornea, pupil, lens, retina
the size of the pupil is controlled by the
iris
the brain breaks vision into separte dimensions such as color, depth, movement and form and works on each aspect simultaneously. This is called
parallel processing
The minimum amount of stimulation a person needs to detect a stimulus 50% of the time is called.
absolute threshold
the distance between our right and left eyes function to provide us with a cue for depth perception known as
retinal disparity
grass seen through sunglasses appear equally as green as it does without glasses. This best illustrates what
color constancy
the sequencing flashing Christmas lights appeared to generate the appearance of motion. this best shows.
the Phi Phenomenon
