Questions and Answers

Template models assume that:

  • We store a variety of items in visual memory
  • Category membership is determined by randomness
  • Intolerance to deviations is not a concern in template models
  • We store a prototypical item in visual memory (correct)

    • What is a significant concern related to template models according to the text?

  • Tolerance to deviations
  • Inability to cope with context effects
  • Low processing speed
  • Huge memory requirements (correct)

    • In template models, how is category membership determined?

  • By comparing sensory information to a prototype (correct)
  • By eliminating all deviations
  • By ignoring sensory information
  • By randomly assigning category membership

    • What is one of the limitations of template models mentioned in the text?
