Key points
- Founded by Max Wertheimer, Wolfgang Köhler, and Kurt Koffka in the early 20th century; Wertheimer’s 1912 paper on the phi phenomenon marks the formal start. Core claim: “the whole is something else than the sum of its parts.”
- Eight named principles of perceptual organization: proximity, similarity, closure, continuity, common fate, symmetry, figure-ground organization, and the law of past experience.
- Explicitly names interface design (radio-button placement) as a field these principles apply to, alongside cartography and desktop layout design; cites the IBM logo as a closure example and a Mississippi River map as a combined similarity/closure/proximity/continuity example.
- Documented criticism: the theory is more descriptive than explanatory — it reliably names perceptual effects without a precise, settled mechanism for why they occur, and some textbooks call the “laws” vague as stated.
