Conformal structures in perceptual psychology

Peter Dodwell was the first to realize the significance of conformal geometry and conformal mapping for perceptual psychology. The importance of conformal properties in perception is now well recognized, and its key role in explicating perceptual phenomena demonstrated. The pioneering efforts of Professor Dodwell in this regard are described, and the application of conformal ideas to basic perceptual invariants, form memory, and the visual Gestalt is traced.
