November 3, 1979 some task (say, to play chess, understand children's stories, write detective stories); one seriously concerned with constructing behaviour theories must ask oneself how such structures could be built up. Can they be built up at all? What primitive learning processes and what training sequences should be postulated to enable the building up of such structures? Are these postulated processes and training sequences tenable from the developmental viewpoint? The essential weakness of currently fashionable AI studies is that they do not concern themselves with such issues at all. In the absence of such concerns, modelling tends to be a series of ad hoc exercises.
