Gordon Pask's contributions to psychology

This paper reviews the contributions of Gordon Pask, cybernetician, to the discipline of psychology as a methodologist and as a theoretician. Pask was prolific in many fields but especially so in psychology both as an innovat ive experimenter and an innovative theorist Over four decades, Pask carried out experimental studies of learning, problem solving and decision making, often using sophisticated computer-based environments. These latter, in tu rn, inspired the design of teaching machines and learning environments with practical applications in education and training. Pask's theorizing while addressing detailed methodological and conceptual issues was also holistic and unifying in intent, not least in his proposals for rapprochements betwe en process, individual and social psychologies.
