The proposal to add the behavioral momentum metaphor to Skinnerian psychology and the use of other borrowed physical explanatory concepts such as velocity and inertial mass has only superficial value. The basic problem is that, in contrast to Newtonian physics, the “laws” do not apply to a significant proportion of the phenomena to be explained, and these evidential discrepancies are ignored, rather than being used to modify the scientific explanations and improve technological applications that are based on those explanations.

Although conditional stimulus (CS)/unconditional stimulus (US) contingency awareness appears to be necessary for human Pavlovian autonomie conditioning, only a selective review of the literature and the forgetting of certain basic, brute facts can allow the cognitive conclusion that awareness causes, or even is important for, conditioning. That conclusion is theoretically barren for explaining the phenomenon and is also of little potential practical use.
