conversion of one form of energy to another in mental processes

(a)  

study of the relationships between physical characteristics of stimuli (ex: intensity), and our experiences of them

(a)  

minimum stimulus energy required to detect stimulus 50% of the time

(a)  

Detecting faint stimuli among other stimuli is determined by someone's experience, motivation, expectations, and alertness

(a)  

below ones absolute threshold for conscious awareness

(a)  

minimum difference between two stimuli to detect 50% of the time (viewed as "just noticeable")

(a)  

the often unconscious associations predisposing perception memory or response

(a)  

to be perceived as different two stimuli must vary by a minimum percentage

(a)  

mental predisposition to perceive one thing and not another

(a)  

the eyes clear outer protective layer covering pupil and iris

(a)  

adjustable opening in the center of the eye

(a)  

controls size of pupil opening and is eye color

(a)  

transparent structure behind pupil that changes shape to focus on images

(a)  

light sensitive inner surface of eye containing rods and cones

(a)  

focusing on objects near or far in retina

(a)  

detect movement and night vision retinal receptors

(a)  

detect color retinal receptors

(a)  

nerve that carries neural impulses from eye to brain

(a)  

central focal point on retina where cones cluster

(a)  

nerve cells in the brain that respond to specific features of a stimulus such as shape or color

(a)  

tendency to integrate info into meaningful wholes

(a)  

the organization of objects to stand out from their surroundings

(a)  

lab device for testing depth perception in babies and young animals

(a)  

depth cue that depends on the use of two eyes

(a)  

depth cue dependable on either eye alone

(a)  

illusion of movement when blinking lights flash in a pattern

(a)  

perceiving objects as having unchanging color size and shape

(a)  

tones experienced highness or lowness

(a)  

chamber of ear that concentrates vibrations on the oval window

(a)  

coiled, bony, fluid filled tube in inner ear that translates sound waves to nerve impulses

(a)  

damage to nerves in ear form of hearing loss

(a)  

damage to mechanical system that conducts sound waves to the cochlea

(a)  

in hearing the theory that relates pitch to where we perceive sounds from

(a)  

the rate of nerve impulses in the auditory nerve matches frequency allowing us to sense pitch

(a)  

the combination of the place and frequency theory (we have to ears to let us hear 3 dimensionally)

(a)  

our movement sense of individual body parts

(a)  

sense of body movement and position

(a)  

the influence of bodily sensations, gestures, and other states on cognitive preferences and judgements
