Question	Answer
Sensation	is the activation of the sense organs by a source of physical energy
Perception	- is the sorting out, interpretation, analysis, and intergration of stimli carried out by the sense organs and brain.
Stimulus	is any passing source of physical energy that produces a response in a sense organ
Psychophysics	study of the relationship between the physical aspects of stimuli and our physical experience of them
Absolute Threshold	smallest intensity of a stimulus that must be present for it to be detected
Difference Threshold	-smallest level of added (or reduced) stimulation to sense that a change in stimulation has occurred
Weber’s Law	States that a just noticeable difference in a constant proportion of the intensity of an initial stimulus
Adaptation	is an adjustment in sensory capacity after prolonged exposure to unchanging stimuli
Gestalt Laws of Organization	some of the most basic perceptual processes can be described by a series of principles that focus on the ways we organize bits and pieces of information into meaningful wholes
Top-Down Processing	Perception is guided by high-level knowledge, experience, and motivations
Bottom-Up Processing	Consists of the progression of recognizing and processing information from individual components of a stimuli and moving to the perception of the whole
Depth Perception	Ability to view the world in 3-d and to perceive distance
