Questions and Answers

What is the Retinal movement system?

  • A system that detects movement across the cornea
  • A system that detects movement across the retina (correct)
  • A system that detects movement across the occipital lobe
  • A system that detects movement across the frontal lobe
  • What activates V9?

  • colour
  • motion
  • gradient
  • eye movements (correct)
  • Grandmother cells are highly specific cells.

    True

    6 month old babies can tell 2 monkeys a part. This ability stays with them for the rest of their lives.

    What can we conclude from Thatcher illusions?

    <p>The face is made of various features in which faces are recognised holistically.</p> Signup and view all the answers

    Tanake & Farah presented cartoon faces. The participants had to learn them then were presented with a single feature from those cartoon faces (e.g.nose). The participants had to figure out which face the single feature belonged to. Results were :

    <p>Participants found it difficult to identify which face the feature belonged to especially when the faces were not present.</p> Signup and view all the answers

    Negative images (where light areas appear dark and vice versa) makes it difficult to identify faces.

    Study Notes

    Retinal Movement System

    • No information provided about the Retinal movement system

    Visual Perception

    • 6-month-old babies can distinguish between two monkeys, and this ability remains throughout their lives

    Face Perception

    • Grandmother cells are highly specific cells
    • Tanake & Farah's study: participants learned cartoon faces and then identified single features (e.g. nose) to recognize the corresponding face
    • Results: negative images (light areas appear dark and vice versa) make face identification difficult

    Motor Control

    • The PMd (premotor dorsal area) is responsible for external-generated actions
    • The Supplementary Motor Area has unknown functions (question did not specify which function is NOT part of it)

    Neuroplasticity

    • Long-term potentiation (LTP) has unknown principles (question did not specify which principle is NOT part of LTP)

    Visual Illusions

    • Thatcher illusions: no specific conclusion mentioned

    Activation

    • V9 is activated by unknown stimuli (question did not specify what activates V9)
