the detection of physical energy by sense organs, which then send information to the brain
the brain's interpertation of raw sensory inputs.
the process of converting an external energy or substance into neural activity
the lowest level of a stimulus needed for the nervous system to detect a change 50% of the time
when we first encounter something it activates.
the processing of sensory information that occurs below the level of conscious awareness. only aspects of it research supports.
process by which we perceive stimuli consistently across varied conditions.
ex. Shape- door whether its open or closed its still a rectangle, Size- near and far.
the process of selecting one sensory channel and ignoring or minimizing others. (broadbent filter theory)
perception of events outside the known channels of sensation.
no replication with multiple endpoints.
part of eye containing transparent cells the focus light on the retina
part of the eye that changes curvature to keep images in focus.
membrane at the back of the eye responsible for converting light into neural activity
receptor cells in the retina allowing us to see in low levels of light
trasmits impluses from the retina to the rest of the brain
ability to judge distance and 3-dimensional relations
stimuli that enables us to judge depth using only one eye.
a table with checkered cloth that drops to the floor which has the same cloth, a clear glass surface extends from the table out over the floor. infants hesitate to go past the table b/c of depth perception
bony spiral-shaped sense organ used for hearing
the presentation of dissimilar sounds to the two ears.
