After studying the chapter, the student should be able to . . .
|
|
|
Contrast allocentric and egocentric direction, including vernier acuity (a hyperacuity) and the effects of inversion of the retinal images. |
|
|
|
Distinguish between absolute and relative distance, and discuss why making this distinction is important for depth perception. |
|
|
|
Specify the oculomotor cues to depth perception (convergence and accommodation), and explain how each one aids in 3-D perception. |
|
|
|
Describe binocular parallax, stereopsis, and stereoscopes. Free fuse (the 5 percent or so of students who are stereoblind will be unable to appreciate stereograms even if they can free fuse). |
|
|
|
Discuss how retinal disparity varies with relative depth across the horoptor. Describe how random-dot stereograms are constructed, how they illustrate difficulties in feature matching between the two eyes' images, and how the feature-matching problem could be solved. |
|
|
|
Describe the neurobiological hardware involved in stereoscopic vision, including the function of disparity-selective cells. |
|
|
|
Discuss the various phenomena and conditions associated with failure of feature matching of the two eyes' images, including binocular rivalry, stereoblindness, strabismus, and amylyopia. Explain convergence insufficiency. |
|
|
|
Explain what is meant by monocular depth cues. |
|
|
|
Specify and explain in detail each of the static cues for monocular depth perception. |
|
|
|
Explain the relations between perceived distance and perceived size, illustrating with the Ames room and the moon illusion. |
|
|
|
Explain motion parallax and how it provides cues for depth perception. |
|
|
|
Discuss how depth cues relate to each other (such as the similarities between motion parallax and stereopsis) and how they are integrated. |
|
|
|
Discuss the depth theory as an explanation for the occurrence of errors in perceived size using well-known size illusions as examples. |
