This book presents the cybernetic theory of learning and the evidence which supports it. Learning is more than the openloop forming of new stimulus-response associations--it is a process of reorganization of sensory feedback within a closed loop, or pattern, which increases the learner's level of control over his own behavior and the stimuli in his environment. Thus learning is space-organized rather than time-organized. After reviewing the evolutionary development of human learning and its differences from its animal counterpart, the book discusses the meaning of present experimental evidence on learning and shows how human learning is dependent on the design of the learning situation, especially the techniques and the instruments of education. Lastly the implications of the concept of feedback learning are discussed in terms of modern educational technology, especially audiovisual systems and teaching machines. A general overview of learning theories other than behavior cybernetics is included. (BB)
