  • Gregory's (1972) Theory of indirect perception
    • Intro to Constuctivist Approach
      • Percieving - Combining information from the senses with what we already know.
      • Constructivist - Perception must be constructed from this incomplete input.
      • Top-Down processes help 'fill the gaps'
    • Top-Down, Recognition Driven Perception
      • Top Down - The image arriving on the retina is incomplete and needs to be 'worked on' by stored knowledge, past experiences e.t.c.
      • Recognition Driven: The end point of perception is to correctly identify what we are looking at.
    • Key Principles
      • Sense input is insufficient for perception. There is a need for an interaction between sensory input and knowledge
      • Much of the information that reaches one's eye is lost by the time it reaches the brain.
      • Perception involves hypothesis testing to make sense of information from our sense organs
        • Incorrect hypotheses will lead to perceptual errors
    • Hypothesis Testing
      • At first glance, the photo looks like random blobs.
      • If one is told what this image is, the image will resolve itself.
        • The photo has not changed although your knowledge about the image has changed.
        • It allows you to generate a reasonable hypothesis of what the figure contains.
