Perception
infoWhy this? Studying perception helps us explain how sensory information becomes meaningful and why visual experience can differ from physical reality. Comparing Gibson’s and Gregory’s theories develops our ability to judge competing accounts of the roles of sensory information and prior experience.
scheduleWhy now? Building on Memory, we move from how experience is retained and reconstructed to how incoming information is perceived. The contrast between direct and constructivist explanations extends our evaluation of competing theories and introduces nature–nurture questions that are explored further in Development.

- Factors affecting perception – culture, motivation, emotion and expectation
