perception

psychological process of giving meaning to what was sensed
sensation is
physical experience of seeing, hearing, or sensing in some other way
absolute threshold
weakest level of sensory stimulation necessary for sensation to occur
difference threshold
just noticeable difference
the smallest difference between two stimuli that is detectable
sensory adaptation
weakened magnitude of a sensation when we have prolonged expossure to stimuli
selective attention
affects which stimuli we notice
psychophysics
specialty area of psych that studies sensory limits, adaptation, and related topics. They try to quantify just noticeable differences.

*****big picture down to tiny detail
visual illusion
visual stimuli in which the clues used in visual percpetion create a false or incorrect perception
pitch
how high or low a sound is based upon the frequency of the sound waves
