ABSTRACT
Recently much perceptual experimentation has involved recording from electrodes implanted in some part of an animal's perceptual system. In this way, for example, some single cells in cats' visual cortices have been found to respond to an edge of a particular orientation and others to edges moving in a certain direction. Such research can provide valuable insights about the receptors and the processing of information in perceptual systems (see McCollough, 1965; Skowbo, Timney, Gentry and Morant, 1975). Our psychological theories should not be inconsistent with physiological findings, and can often find useful ideas in such research.
