What you'll learn
How we interpret sensory information.
Key ideas
- Perception interprets sensation.
- Gibson: direct, bottom-up perception (e.g. motion parallax).
- Gregory: top-down, using inference and experience.
- Depth cues: monocular and binocular; size constancy.
Exam tips
- Contrast Gibson and Gregory directly.
- Use illusions to evaluate the theories.
Common mistakes
- Confusing bottom-up with top-down.
- Mixing up monocular and binocular cues.
