The major contributions of operationism have been negative, largely because operationists failed to distinguish logical theories of reference from empirical accounts of language. Behaviorism never finished an adequate formulation of verbal reports and therefore could not convincingly embrace subjective terms. But verbal responses to private stimuli can arise as social products through the contingencies of reinforcement arranged by verbal communities.

There seem to be two kinds of pain: fundamental pain, the intensity of which is a direct function of the intensity of various pain stimuli, and pain, the intensity of which is highly modifiable by such factors as hypnotism, placebos, and the sociocultural setting in which the stimulus occurs.

Ullin Place's contributions to the literature of behaviour analysis and behaviourism span the period from 1954 to 1999. In appreciation of his scholarship and breadth of vision, this paper reviews an early widely-cited contribution ("Is consciousness a brain process?" British Journal of Psychology, 1956, pp. 47-53) and a late one which should become widely cited ("Rescuing the science of human behavior from the ashes of socialism," Psychological Record, 1997, pp. 649-659). It is noted that the sweep of Place's work links (...) behaviour analysis to its philosophical roots in the work of Ryle and Wittgenstein and also looks forward to the further functional analysis of language-using behaviour.
