Science and Human Behavior, Chapter 5: Operant Behavior, Quote 9

“The only way to tell whether or not a given event is reinforcing to a given organism under given conditions is to make a direct test. We observe the frequency of a selected response, then make an event contingent upon it and observe any change in frequency. If there is a change, we classify the event as reinforcing to the organism under the existing conditions.” (pp. 72-73)
