Impetus for a robust science of behavior: A review of Nevin's <i>Behavioral Momentum: A scientific metaphor</i>
Behavioral momentum is a handy image, but Catania urges you to weigh it against simpler, measurable tactics before building whole interventions around it.
01Research in Context
What this study did
Charles Catania (2018) read John Nevin’s book on behavioral momentum. He wrote a long essay that checks the metaphor against real data.
The paper is a narrative review. It pulls older studies together and asks, "Does momentum really explain why behavior keeps going?"
What they found
Catania says the momentum picture is useful but incomplete. He warns that other ideas, like economic cost or fluency, may fit the same facts better.
No new numbers are given. The job is to flag gaps before teachers or clinicians bank on the metaphor.
How this fits with other research
Lyons (1995) first linked momentum to price in economics. Catania keeps that link but asks if we need both frames.
McDowell (2017) reviewed a different metaphor—goal-based models. Both reviews end with the same warning: metaphors help until they hide simpler rules.
Fraley (1998) showed how basic behavioral tasks can test cognitive ideas. Catania wants the same hard tests done on momentum before we scale it up.
Why it matters
If you run fluency programs or use high-rate practice to build "behavioral mass," pause. Check the data behind the metaphor. Try comparing momentum tactics against a plain rate-building plus reinforcement plan. Track which set of procedures keeps skills alive longer. That quick test keeps your clinical choices grounded, not just poetic.

03Original abstract
Nevin provides a scientific role model, illustrating momentum in his own research and providing impetus through his effects on the scientific behavior of his students and his colleagues. I discuss his book in the context of a review of the history of the concept of extinction, I cite his introduction of signal‐detection analysis into behavior analysis as a contribution not covered in this book, I briefly consider applications, such as the potential extension to fluency procedures in education, and I critique his concept of momentum, relating it to other metaphors for maintained behavior such as the dynamics of sensory systems and robustness in biological accounts of the stability of phenotypes.
