1

The stimulation of sense organs

Sensation

2

The selection, organization, and interpretation of sensory input

Perception

3

The minimum stimulus intensity an organism can detect; its probability of detection is 50%

Absolute Threshold

4

Proposes that stimulus detection involves decision processes as well as sensory processes, both which are influenced by a variety of factors besides stimulus intensity

Signal-Detection Theory

5

Registration of sensory input without conscious awareness

Subliminal ("Below the threshold")

6

Gradual decline in sensitivity to prolonged stimulation

Sensory adaptation (ex. garbage doesn't smell after awhile)

7

(In vision) Determines the color you see

Wavelength

8

(In vision) Determines brightness (affects the color you see)

Amplitude

9

wavelengths humans can see

Regulates light in the eye

Pupil

13

Where light enters the eye

Cornea

14

Receives light in the eye

Putting more light in a mixture than exists

Additive Color mixing

28

Removing wavelengths of light in a mixture

Subtractive Color mixing

29

says that the human eye has 3 types of receptors sensitive to specific wavelengths associated with red, green, and blue

Trichromatic theory
