Stadler, M.A., & Frensch, P.A. (Eds.) (1998). Handbook of implicit learning. London: Sage. 636 pp. ISBN: 0-761-90197-3 Psychologists have long been interested in what has come to be called implicit learning (Reber, 1967). In various guises the topic has remained close to the surface of academic consciousness throughout the history of the discipline (e.g. Thorndike & Rock, 1934; Greenspoon, 1955). However, over the past 30 years the literature on implicit learning, has burgeoned and the publication of the Handbook of implicit learning represents a long overdue recognition of the importance of this, at times controversial, topic.
