Questions and Answers

According to template theory, what do template theorists argue exists in our mind?

  • Infinite storage of sensory experiences
  • Abstract concepts unrelated to perception
  • Unlimited capacity for new recognition
  • Templates or object representations of things we have perceived before (correct)
  • What is a drawback of the template theory from a Biological Plausibility standpoint?

  • The brain lacks the capacity to store templates
  • Storing trillions of templates is not efficient for object recognition (correct)
  • Templates cannot be updated with new information
  • Templates are not flexible enough for varied experiences
  • What real-life application is provided as an example related to the template theory?

  • Digital image processing
  • Barcodes representing the same thing (correct)
  • Augmented reality experiences
  • Virtual reality simulations
  • What is the main challenge that the template theory suffers from?

    Study Notes

    Theories of Object Recognition and Brain Processing

    • Captcha is a bot prevention program using distorted letters to prevent template recognition by bots
    • Top-Down processing theory suggests that we recognize objects as a whole and switched to words to aid perception
    • Feature Analysis Theory argues that we recognize objects by identifying a combination of features
    • The RBC model by Biederman suggests that we recognize objects by 3D components called geons
    • The model explains that adding color and texture makes it easier to distinguish objects
    • Limitations of the RBC model include difficulty in recognizing objects with unique features
    • The ongoing debate is whether we recognize objects as parts or as a whole
    • Repetition Suppression (RS) phenomenon suggests that brain activation lessens with repeated exposure to an object
    • Perspective of objects matters in perceiving them, as shown by RS experiments
    • Left hemisphere of the brain is view invariant, while the right hemisphere is view dependent
    • Dorsal and Ventral Streams are two parallel processing pathways for perceiving information
    • The Ventral Stream helps identify objects and link them to memory, while the Dorsal Stream helps understand object location and usage
