Transduction
|
Process by which our sensory systems encode stimulus energy as neural messages.
|
|
Pupil
|
small adjustable opening where light enters
|
|
Iris
|
colored muscle surrounding the pupil which controls the size of the pupil opening
|
|
Lens
|
focuses the incoming rays into an image
|
|
accommodation
|
changing lens curvature to focus near or far objects
|
|
Retina
|
eyeball's light sensitive inner surface on which the rays focus is a multilayered tissue
|
|
Hue
|
dimension of color that is determined by the wavelength of light.
|
|
Describe Retina's reaction to light
|
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.
|
|
Optic nerve
|
that carries information to the brain
|
|
Blind spot
|
where the optic nerve leaves the eye there are no receptor cells creating a blind spot
|
|
Feature Detector Neurons
|
respond to specific features such as as edges, lines, angles, and movements.
|
|
parallel processing
|
brain's natural mode of information processing for many functions.Color, motion, form, depth
|
|
three color theory
|
theory that the retina contains three different color receptors. Red, green, blue
|
|
opponent-process theory
|
theory that opposing retinal processes enable color vision.
|
|
color constancy
|
consistent color even if changing illuminations.
|
|
Cochlea
|
coiled fluid filled tube in the inner ear. Sound waves trigger nerve impulses.
|
|
sensory interaction
|
says that one sense may influence another, as when the smell of food influences its taste
