Psychology Chapter 5&6

Front 1

Transduction

Back 1

Process by which our sensory systems encode stimulus energy as neural messages.

Front 2

Pupil

Back 2

small adjustable opening where light enters

Front 3

Iris

Back 3

colored muscle surrounding the pupil which controls the size of the pupil opening

Front 4

Lens

Back 4

focuses the incoming rays into an image

Front 5

accommodation

Back 5

changing lens curvature to focus near or far objects

Front 6

Retina

Back 6

eyeball's light sensitive inner surface on which the rays focus is a multilayered tissue

Front 7

Hue

Back 7

dimension of color that is determined by the wavelength of light.

Front 8

Describe Retina's reaction to light

Back 8

light strikes cones and rods which produces chemical energy that generate neural signals. Then these signals active the neat bipolar cells, which then activate ganglion cells.

Front 9

Optic nerve

Back 9

that carries information to the brain

Front 10

Blind spot

Back 10

where the optic nerve leaves the eye there are no receptor cells creating a blind spot

Front 11

Feature Detector Neurons

Back 11

respond to specific features such as as edges, lines, angles, and movements.

Front 12

parallel processing

Back 12

brain's natural mode of information processing for many functions.Color, motion, form, depth

Front 13

three color theory

Back 13

theory that the retina contains three different color receptors. Red, green, blue

Front 14

opponent-process theory

Back 14

theory that opposing retinal processes enable color vision.

Front 15

color constancy

Back 15

consistent color even if changing illuminations.

Front 16

Cochlea

Back 16

coiled fluid filled tube in the inner ear. Sound waves trigger nerve impulses.

Front 17

sensory interaction

Back 17

says that one sense may influence another, as when the smell of food influences its taste
