Some remarks on the quantitative analysis of behavior.
Treat response rate as your main ruler and model reinforcement as the push that changes it.
01Research in Context
What this study did
This paper is a call to arms, not an experiment. The author urges behavior analysts to treat response rate like physicists treat motion. Measure it precisely. Model it with equations. Link tiny moment-to-moment responses to big daily patterns.
No clients, no sessions—just a map for future science.
What they found
The big idea: reinforcement works like a physical force. Push it and the rate of response changes. Track that rate as your main number. Build Newton-style formulas that connect single clicks, bites, or words to long stretches of behavior.
How this fits with other research
Staddon et al. (2002) took the advice and built real math. They used Poisson and Markov models to turn response probability into predicted rate. Jones et al. (2010) went further, writing two-part differential equations that show how reinforcement ‘force’ moves choice on concurrent schedules.
Skinner et al. (1958) had already shown how to define an operant unit so rate could even be counted; Marr (1989) simply asked us to treat that number as the center of our universe.
Sosa et al. (2022) push back. They say Newton is the wrong metaphor. Feedback-control loops, not force-and-motion, better explain why behavior stays stable. The clash is friendly: both camps want equations, but one wants pushes, the other wants thermostats.
Why it matters
If you graph rate in real time you already follow this paper. Next step: try the simple equations from Staddon et al. (2002) or Jones et al. (2010) in Excel. See if your client’s data fit. The exercise sharpens treatment decisions and keeps us close to hard science.

03Original abstract
This paper discusses similarities between the mathematization of operant behavior and the early history of the most mathematical of sciences-physics. Galileo explored the properties of motion without dealing with the causes of motion, focusing on changes in motion. Newton's dynamics were concerned with the action of forces as causes of change. Skinner's rationale for using rate to describe behavior derived from an interest in changes in rate. Reinforcement has played the role of force in the dynamics of behavior. Behavioral momentum and maximization have received mathematical formulations in behavior analysis. Yet to be worked out are the relations between molar and molecular formulations of behavioral theory.
