Front 1

Sensation

Back 1

the process by which our sense organs receive information from the environment

Front 2

Perception

Back 2

Front 3

stimuli

Back 3

energy that produces a response in a sense organ

Front 4

psychophysics

Back 4

the study of the relationship between the physical aspects of stimuli and our psychological experience of them.

Front 5

absolute threshold

Back 5

the smallest of intensity of a stimulus that must be present for the stimulus to be detected

Front 6

difference threshold

Back 6

the smallest level of stimulation required to sense that a change in stimulation has occured

Front 7

Weber's Law

Back 7

one of the basic laws of psychophysics, that a noticeable difference is in proportion to the intensity of the stimulus

Front 8

Adaption

Back 8

an adjustment in sensory capacity following prolonged exposure to stimuli

Front 9

Feature detection

Back 9

the activation of neurons in the cortex by visual stimuli of specific shapes or patterns

Front 10

Back 10

the theory that the three different cones in the retina responds to it's own things

Front 17

Top-Down processing

Back 17

perception that is guided by higher level knowledge and experience

Front 18

Bottom-Up processing

Back 18

perception that consists of processing information about the components of the stimuli

Front 19

Visual- Illusions

Back 19

physical stimuli that produce errors in perception
