Psychology Unit 1 Assessment

2. The Orbital Cavity
 The orbital cavity is the part of
the skull that holds the eyeball
and feeds the optic nerve into
the brain.

3. 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.

4. 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.

5. Sensation
 Sensation occurs
when we initially
intake any energy
into our body.
 Like in this case
when light first
makes contact
with the eye.

6. 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.

7. 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.
