Cards

Term
kinesthesis
Definition
the system for sensing the position and movement of individual body parts
Term
sensation
Definition
process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment
Term
perception
Definition
process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
Term
bottom-up processing
Definition
analysis that beings with the sensory receptors and works up to the brain's integration of sensory information
Term
top-down processing
Definition
information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations
Term
absolute threshold
Definition
the minimum stimulation needed to detect a particular stimulus 50% of the time
Term
(subliminal) priming
Definition
the activation (often unconsciously) of certain associations, thus predisposing one;s perception, memory, or response
Term
difference threshold
Definition
the minimum difference between two stimuli required for detection 50% of the time
Term
sensory adaptation
Definition
diminished sensitivity as a consequence of constant stimulation
Term
transduction
Definition
conversion of one form of energy into another
Term
accommodation
Definition
process by which the eye's lens change shape to focus near of far objects on the retina
Term
retina
Definition
light sensitive inner surface of the eye, containing receptor rods and cones plus layers of neurons that begin the processing of visual info
Term
rods
Definition
retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision when cones don't respond
Term
cones
Definition
retinal receptors concentrated near the center of the retina; that function in daylight or well-lit conditions; detect fine detail and give rise to color sensation
Term
fovea
Definition
the central focal point in the retina, around which the eye's cones cluster
Term
blind spot
Definition
point at which the optic nerve leaves the eye, creating a "blind spot" b/c no receptor cells are located there
