As Skinner (1938) described it, response strength is the “state of the reflex with respect to all its static properties” (p. 15), which include response rate, latency, probability, and persistence. The relations of those measures to one another was analyzed by probabilistically reinforcing, satiating, and extinguishing pigeons' key pecking in a trials paradigm. Reinforcement was scheduled according to variable‐interval, variable‐ratio, and fixed‐interval contingencies. Principal components analysis permitted description in terms of a single latent variable, strength , and this was validated with confirmatory factor analyses. Overall response rate was an excellent predictor of this state variable.
