  4. David Hubel and Torsten Wiesel • Discovered that groups of neurons in the visual cortex respond to different types of visual images. • Visual cortex has feature detectors for vertical lines, curves, motion, and many other features of images.

  5. Ernest Weber • Psychophysics who computed Weber’s Law • For people to perceive a difference, the stimulus must differ by a constant proportion not a constant amount. • Weber’s Law- related to the just noticeable difference, which is the minimum difference in stimulation that a person can detect 50% of the time.

  6. Gustav Fechner • Contributor to Weber’s Law • Some textbooks refer to this law as the Weber-Fechner Law

  7. Eleanor Gibson • Researcher who used the visual cliff experiment to determine when human infants can perceive depth. • Found that an infant old enough to crawl would not crawl over the glass top table inferring they have developed depth perception.
