E. C. Tolman's ‘purposive behaviorism’ is commonly interpreted as an attempt to operationalize a cognitivist theory of learning by the use of the ‘Intervening Variable’ (IV). Tolman would thus be a counterinstance to an otherwise reliable correlation of cognitivism with realism, and S-R behaviorism with operationalism. A study of Tolman's epistemological background, with a careful reading of his methodological writings, shows the common interpretation to be false. Tolman was a cognitivist and a realist. His ‘IV’ has been systematically misinterpreted by both behaviorists and antibehaviorists. For this reason, Tolman's alliance with modern cognitivism and his influence on its development have been underestimated.

Ritchie, Paul Meehl, and a most perceptive anonymous referee. Research for this project has been supported by the National Endowment for the Humanities during the summers of 1980 and 1981.
