Outline of Section 4 Lecture Topics


Below is an outline of the topics covered in lecture before Exam 4. The outline is not split into different
lectures. It is not a substitute for class lectures, but is intended only to help you organize your notes.

  1. Perception of Depth/Distance
    1. Three Types of Depth/Distance Cues
      1. Oculomotor Cues
      2. Monocular Cues
        1. Pictorial Cues
        2. Movement Cues
      3. Binocular Vision - Stereopsis
        1. Binocular (Retinal) Disparity - Cues to Depth
          1. Crossed vs Uncrossed Disparity
          2. Angle of Disparity
        2. Stereopsis
          1. The correspondence problem
          2. Random-dot stereograms
          3. Binocular cortical neurons - disparity detectors
          4. Development of Stereopsis
            1. Normal development
            2. Deprivation studies
            3. Critical Period
    2. Size Constancy
      1. Size-Distance Scaling / Emmert's Law
      2. The Effect of Perceived Distance on Perception of Size
        Holway & Boring Experiment
      3. Size/Depth Illusions

  2. Perception of Motion
    1. Motion Pathways in the Brain - "Dorsal" pathway, MT and MST
    2. Important Functions of Movement Information in Perception
    3. Defining "Movement" in Vision
    4. Two Movement Systems
      1. Image-Retina System
        1. Complex Cells
        2. Reichardt detectors
        3. Motion aftereffect
        4. MT neurons
        5. Apparent Motion
      2. Eye-Head System
        1. Three Types of Eye Movements
          1. Saccadic
          2. Pursuit
          3. Vestibular
        2. Corollary Discharge Theory
          1. Comparator
          2. Evidence - Neurons in V3, MT
    5. Using Motion Information to Guide Action
      1. Maintaining/Judging Heading
      2. Judging Time of Arrival
