Cumulative Record. Chapter 45: John Broadus Watson, Behaviorist. Quote 8

… Watson was to be remembered for a long time, by both laymen and psychologists alike, for a too narrow interpretation of self-observation, for an extreme environmentalism, and for a coldly detached theory of child care, no one of which was a necessary part of his original program. His brilliant glimpse of the need for, and the nature and implications of, a science of behavior was all but forgotten. (p. 604)
