ABSTRACT

David Lee’s article on “The Functions of Vision”, published in 1978 but based

on workshops held in 1974 and 1975, appears in a volume edited by Herbert

Pick and Elliot Saltzman. In their introduction, the editors contrast the

traditional empiricist view of perception as learning and problem-solving

behavior with the “more productive ties between perception and cognition

[which] have evolved from the impact of cybernetics, information theory,

communications and artificial intelligence” (Pick & Saltzman, 1978, p. vii). The

last of these, artificial intelligence (AI), has had a rough ride over the last

quarter-century, but a defining characteristic has remained the belief of its

practitioners that the study of human and animal perception on the one hand, and

the engineering of computer perception on the other, can best progress - perhaps

only progress - by mutual exchange of ideas. I moved from Lee’s laboratory to a

lectureship in AI in 1985, so my interest here is to consider how the ideas in his

article have contributed to this synergy.
