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

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

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

SENSATION vs. PERCEPTION GRIVAS – pg.95 FERAL COLLINGWOOD SUPPORTERS

SENSATION vs. PERCEPTION AMBIGUOUS FIGURES What do you see in the following pictures?

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 GRIVAS – pg.95

CLASSROOM WALKTHROUGH OF THE EYE ACTIVITY THE ROLES OF THE EYE CLASSROOM WALKTHROUGH OF THE EYE ACTIVITY GRIVAS – pg.96-101

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

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

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

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

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

CHARACTERISTICS OF THE VISUAL PERCEPTION SYSTEM RECEPTION TRANSDUCTION TRANSMISSION ORGANISATION INTERPRETATION (see handout and text book for explanation) GRIVAS – pg.98-100
