1. UNIT 1: INTRODUCTION TO PSYCHOLOGY
AREA OF STUDY 1: WHAT IS PSYCHOLOGY?

2. SENSATION vs. PERCEPTION
The process by which our sensory organs and receptors detect and respond to sensory information that stimulates them
What are some examples????
GRIVAS – pg.95

3. SENSATION vs. PERCEPTION
The process by which we give meaning to sensory information, resulting in our personal interpretation of that information
GRIVAS – pg.95

7. 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
GRIVAS – pg.95

8. CLASSROOM WALKTHROUGH OF THE EYE ACTIVITY
THE ROLES OF THE EYE
CLASSROOM WALKTHROUGH OF THE EYE ACTIVITY
GRIVAS – pg

9. 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
GRIVAS – pg.96-97

10. 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.
GRIVAS – pg.96-97

11. 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
GRIVAS – pg.96-97

12. STRUCTURES IN THE EYE
OPTIC NERVE
Connects the retina to the Visual Cortex for further processing of visual information
GRIVAS – pg.96-97

14. RODS AND CONES RODS CONES Respond to low levels of light
Responsible for night vision
Poor at detecting fine detail and are not involved in colour vision
Respond to high levels of light
Responsible primarily for day vision
Good at detecting fine detail and colour
GRIVAS – pg.99
