On the possibility of "smart" perceptual mechanisms.

.— A basic feature of some modem theories of perception is the notion of complex or higher order variables which are considered basic for perception. A distinction between “rote” and “smart” mechanisms is introduced and it is suggested that perception consists of smart mechanisms which directly register complex variables. A model of a perceiver, based on the smart polar planimeter, is constructed and used to illustrate the possible consequences of smart perceptual mechanisms for research in areas such as psychophysics, cognition, attention, and perceptual development and learning.
