- Why is object perception a difficult problem? Explain the inverse projection problem, occlusion, and viewpoint invariance
- Think of examples of how heuristics and knowledge influence object perception.
- Draw or recognize picture(s) demonstrating the Gestalt laws of perceptual organization.
- Give an example of the Gestalt idea of transposable.
- What are properties that separate a figure from its background?
- Can infants perceive objects by grouping principles? What is evidence for this?
- What are the two stages of processing in the feature integration theory?
- Distinguish between displays that would recruit the first or second stage. How does reaction time demonstrate the difference?
- Describe examples of inattentional blindness and change blindness. What does this tell us about the relationship between attention and perception?
- What are three dimensions of color?
- What is the difference between additive and subtractive color mixing?
- How does the wavelength spectrum correspond to perceived hue?
- What are spectral vs. non-spectral colors?
- What is the main claim of the trichromatic theory of color vision? Describe the sensitivity functions of the three cone receptors.
- What is a metamer?
- How does the opponent process theory of color explain afterimages?
- Describe the perceptual experience of a dichromat. In terms of the neurophysiology of the retina, explain the cause of dichromatism.
- Describe how the ratio principle explains our experience of lightness constancy.
- What is the difference between a reflectance edge and an illumination edge?
- How do accommodation and convergence help in perception of depth?
- What is binocular disparity and stereopsis?
- What are random dot stereograms?
- Describe the difference between corresponding and noncorresponding points when talking about binocular disparity.
- How can you use eye-height to judge size?
- How does height in the field give a cue to distance?
- Give examples and explain the secondary depth cues talked about in class.
- What is the relationship between the size of an object on your retina and distance from you? How does this relationship explain illusory effects (such as Ponzo illusion)?
- How is low vision defined? What are some examples?
- Why is visual accessibility an important problem?
- How does spatial learning change with low vision?
