5. Please make your selection Accommodation is • Is a binocular depth cue • Is possible because our eyes are 6 to 7cm apart • Enables an image to be sharply focused onto the retina • Enables our eyes to turn inwards to focus on an object

6. Please make your selection Imagine that you are in a museum. A statue is in the middle of the room. You walk around it and examine it from many places in the room. The retinal image of the statue changes, but you do not perceive the statue as changing. This is known as • Convergence • Motion parallax • Interpositioning • Perceptual constancy

7. Please make your selection Three types of perceptual constancy are: • size, texture and form • Form, shape and texture • Size, shape and brightness • Brightness, texture and form

8. Please make your selection Visual perception processes begin when _____ energy is changed into _____ energy. • chemical; electromagnetic • Electromagnetic; electrochemical • Electromagnetic; chemical • Electrochemical; electromagnetic

9. Please make your selection In the visual perception process, which of the following occurs first? • Selection • Reception • Transmission • Feature detection

10. Please make your selection In visual perception, the process of transduction takes place in • Lens • Pupil • Occipital lobe • photoreceptors

11. Please make your selection If you move an object closer to the viewer • It has little or no effect on the viewer’s perception of the object’s size • It causes the viewer to perceive the object as getting bigger • It changes the viewer’s perception of the object’s shape • It decreases the size of the retinal image of the object

12. Please make your selection The pattern on solider’s uniforms is designed to assist camouflage in a jungle. The camouflage occurs because • The principle of figure-ground is applied • The principle of proximity is applied • The principle of figure-ground is not applied • The principle of proximity is not applied

13. Please make your selection Jemima has had an operation on one eye and has to wear a protective patch. She will probably have some difficulty perceiving the distance of objects because she cannot use • Retinal disparity • Accommodation • Gestalt principles • Pictorial cues

14. Please make your selection A number of depth cues are used when perceiving the Ames room illusion. Which of the following is a depth cue that is NOT used? • figure-ground • Convergence • Accommodation • Linear perspective

15. Please make your selection Visual acuity is greatest • In the fovea where there are only rods • In the fovea where there are only cones • In the area of the retina where there are equal numbers of rods and cones • In the area of the retina where the optic nerve attaches

16. Please make your selection The process of converting one kind of energy to another by cells in the eye is called • Feature detection • Perceptual organisation • Transmission • Transduction

17. Please make your selection The adjustment of the shape of the lens to focus on a near object is known as • Convergence • Retinal disparity • Accommodation • Transduction

18. Please make your selection An open drawer is perceived as having the same shape when seen from the front, the side, or from above. This is an example of • Perceptual constancy • Perceptual set • Similarity • Visual illusion

19. Please make your selection Visual reception involves the • Delivery of the visual information to the appropriate lobe for interpretation • Detection of light by the photoreceptors on the retina • Transmission of a visual image to the brain • Interpretation of the visual information in the brain

20. Please make your selection Luisa woke at night in her darkened room. At first she could not see anything, but after a few minutes, due to the _____ in her eyes, she could see the shape of her dressing gown hanging on the door. When she turned on the light she could see the colour of the dressing gown, due to the action of her _______. • Cones; rods • Rods; cones • Rods; rods • Cones; cones

21. Please make your selection A person with an eye patch over one eye for a long period of time could still perceive depth and distance by using the cues of • Interposition and relative size • Texture gradient and retinal disparity • Convergence and retinal disparity • Linear perspective and convergence

22. Please make your selection Mark is hanging his red shirt, blue shirt and white shirt outside in the sun. Suddenly the sun is covered by a large, dark cloud. The statement that best describes the effect on Mark’s visual perception is • The white shirt appears dimmer than the blue and red shirts • The red and blue shirts appear dimmer than the white shirt • The red and white shirts appear brighter than the blue shirt • All three shirts appear as bright as they did previously

23. Please make your selection When an object is identified as a figure separate from its background, the object is more likely to • Have a distinct shape • Be placed behind another object • Be just as noticeable as its background • Be less dominant than its background

24. Please make your selection Accommodation • Enables our eyes to turn inwards to focus on the object • Is a binocular depth cue • Enables a sharp or focused image to be produced on the retina • Is possible because our eyes are 6 to 7cm apart

25. Please make your selection During accommodation the _____ changes shape and ______ when focusing on a far object • pupil; contracts • Pupil; dilates • Lens; bulges • Lens; elongates
