The Study of VisionPsychology Unit 1 Assessment

The Orbital Cavity The orbital cavity is the

part of the skull that holds the eyeball and feeds the optic nerve into the brain.

Inside the Eye The cornea controls the

light coming from the outside and focuses it onto the pupil.

The pupil is where the light enters and is processed onto the retina.

The retina is where the actual processing of the light occurs and is translated by rods and cones.

The Optic Nerve The optic nerve is where

everything we see travels to the brain. This is where the light signals are perceived and transduction has already occurred.

The brain then recognizes this as light entering the eye in the visual cortex.

Sensation Sensation

occurs when we initially intake any energy into our body.

Like in this case when light first makes contact with the eye.

Transduction Transduction occurs when the

light enters into the eye and is sensed by the rods and cones in the eye.

These rods and cones are what determine what color of the spectrum the light is and finally it translates the light.

Perception After the light is

translated by the rods and cones in the retina it is already converted into an electrochemical signal and makes its way from the optic nerve to the visual cortex.
