Questions and Answers

What are the criteria proposed by Gibson (1969) for selecting an array of features for uppercase letters?

  • The features should change under different lighting conditions
  • The features should yield a unique pattern for each letter (correct)
  • The features should be randomly chosen to provide diversity
  • The features should not be critical

    • According to Hubel and Wiesel (1962, 1963), what kind of stimuli do cells respond to?

  • Stimuli that change frequently
  • Random stimuli with no specific patterns
  • Only certain kinds of stimuli, such as lines of a certain width and orientation (correct)
  • All kinds of stimuli equally

    • What is perceptual confusion in pattern recognition?

  • The frequency with which two patterns are mistakenly identified as each other (correct)
  • The difficulty in identifying familiar patterns
  • The ability to distinguish between similar patterns
  • The ease with which patterns are recognized
