B.J.Zimmerman (1983) illustrated one form of dis enchantment with early cybernetic models by nothing that “Neisser’s 1967 book, Cognitive Psychology, was a widely read, generally sympathetic description of the cybernetic version of information processing. However, in his 1976 text, significantly entitled cognition and reality, Neisser renounced the utility of cybernetic models of human thought because of their limited capacity to describe the complex reciprocal relationship between people and their proximal environment.” Thus, to render information-processing theory sensitive to different environment conditions, revised models need to portext far more precisely than the general provision of “the external environment” in Figure 11.1.
