Introduction

D. O. Hebb is best known for his very influential book, The Organization of Behavior, in which is presented his neuropsychological “cell-assembly” theory (1949). Equally important, but less well appreciated, was Hebb’s determination to see psychology attempt to illuminate cognitive processes which, during the first half of the 20th century, had been subjugated by the behaviorist Zeitgeist (Klein, 1979).
