Key Points: Perception Phenomena> Top-Down and Bottom-Up Processing

  • Top-down processing occurs when perception is influenced by past experience, knowledge, and context.
  • In top-down processing, the brain uses background information to interpret a stimulus.
  • Bottom-up processing occurs when perception is based only on sensory input without the influence of context.
  • In bottom-up processing, perception begins with the stimulus and moves upward to the brain for interpretation.
  • Thus, perception can be influenced either by context (top-down) or purely by sensory data (bottom-up).
