The matching law suggests that operant behavior is determined by rate of reinforcement for one alternative relative to all other known sources of reinforcement. Even in situations where a contingency exists between a single response and reinforcement, organisms may have several reinforced alternatives that are unknown to the researcher. Also, many of the activities that produce reinforcement are beyond experimental control. Thus, in a single-operant setting, multiple sources of reinforcement are operating. In this view, all operant behavior must be understood as behavior emitted in the context of other alternative sources of reinforcement.
:
A dimensional quantity reflecting the time required to emit 2 5 % of the responses that occur during an interval (most often, under a fixed-interval schedule of reinforcement). Provides a way of quantifying the curvature of a cumulative record of responding throughout an interval.
