UNIT 1: INTRODUCTION TO
PSYCHOLOGY
AREA OF STUDY 1: WHAT IS PSYCHOLOGY?
SENSATION vs.
PERCEPTION
SENSATION
The process by which our sensory organs and
receptors detect and respond to sensory information
that stimulates them
What are some examples????
SENSATION vs.

PERCEPTION
The process by which we give meaning to sensory
information, resulting in our personal interpretation of
that information

SENSATION vs.
PERCEPTION
AMBIGUOUS FIGURES
THE VISUAL PERCEPTION
SYSTEM
The complete network of
physiological structures
involved in vision. This
includes all the parts of
the eyes, the nervous
system pathways that
connect the eyes and the
brain, and the areas of
the brain that process
visual information

WALKTHROUGH OF THE

ACTIVITY
STRUCTURES IN THE EYE
CORNEA
PUPIL
IRIS
Light enters through this structure which is
a transparent, convex-shaped covering
that focuses the light rays onto the retina
The opening in the iris that helps to control
the amount of light entering the eye
A ring of muscles that expand or contract
to change the size of the pupil
STRUCTURES IN THE EYE
LENS
RETINA
Focuses light onto the retina. Adjusts its
shape according to the distance of the
object being viewed through use of the
ciliary muscles
Receives and absorbs light, and also
processes the images.
STRUCTURES IN THE EYE
AQUEOUS
HUMOUR
VITREOUS
HUMOUR
A watery fluid which helps to maintain the
shape of the eyeball and provides
nutrients and oxygen to the eye, as well as
carry away waste products
A jelly-like substance which helps to
maintain the shape of the eyeball and
also helps focus light
STRUCTURES IN THE EYE
OPTIC NERVE
Connects the retina to the Visual Cortex
for further processing of visual information
