The Basics

  • Read only the perception sections of Chapter 2

The Buzz

  • Explain the difference between sensation and perception.
  • Explain how bottom-up and top-down processing are involved in perception.
  • Discuss the perceptual organization processes. For each, explain how your perception of the world would be different if that process did not work properly.
  • Explain what synesthesia is and how it is related to non-synesthetes’ everyday experience.
