Visual Perception
Objectives
|
After completing this chapter you should be able to:
- Explain why vision is such a formidable task; focusing on the indeterminacies the visual system has to overcome.
- Understand how neuropsychological and neuroanatomical findings relate to the behavioral processes of visual perception. How can behavior and physiology successful interact with each other?
- Discuss how the visual system resolves ambiguities by making different types of assumptions and describe the assumptions.
- Describe the inverse optics problem and give an example.
- Compare and contrast the evidence for and against the hypothesis that a part of the human brain is specialized for recognizing faces.
- Explain the roles of luminance, shadows, and local contrast in the perception of brightness.
- List and define factors in distance perception, then classify them as to whether they are monocular or binocular.
- Outline the construction of random dot stereograms and explain why our ability to see them is so amazing.
- Contrast the roles of top-down vs. bottom-up processes in visual perception.
- Distinguish between the computational and ecological approaches to the study of vision.
- Discuss the two main goals of vision and review the evidence for separate visual systems that serve these goals.
- Contrast viewer-centered representations with object-centered representations and briefly review the experimental evidence for each.
- Compare and contrast the what/where and what/how hypotheses of object location.
