About the presentation:

Operant conditioning reached a high point in the basement of Memorial Hall at Harvard in the early 1960s. Two figures dominated: S. S. “Smitty” Stevens and R. J. “Dick” Herrnstein (B. F. Skinner was no longer actively involved in laboratory research at that time.) Laws were the thing: Weber-Fechner and the power law at Stevens’ end of the basement; the ‘molar’ (average-rate) matching law of choice in the pigeon lab at Herrnstein’s end. I will show how the power law is based on Weber-Fechner; and how the matching law and a later development, behavioral ‘momentum’, both follow from a principle that incorporates competition from “other” behavior. It turns out that molar laws tell us little about what the subject is actually doing moment-by- moment. In fact, a very simple Darwinian selection/variation law-of- effect process seems sufficient to explain many choice effects.

Upon completion of this presentation attendees will be able to:

  • Describe latent responses
  • Understand how Weber-Fechner and the power law are related
  • Know the difference between concurrent and multiple schedules
