What term captures the principle that the proportion of responses matches the proportion of reinforcement?

• A. Stimulus Generalization
• B. Matching Law
• C. Stimulus Discrimination
• D. Contingency-Shaped Behavior

Answer: (B)

Matching Law explains how an organism distributes its responses when faced with multiple options that deliver different reinforcement rates. It states the proportion of responses allocated to each option tends to mirror the proportion of reinforcement obtained from that option. So if one option provides most of the reinforcement, more responses will go there, roughly in that same proportion, though not perfectly due to factors like bias or undermatching. This principle helps explain why an animal will shift more behavior toward the option yielding more reinforcement. The other terms describe distinct ideas: Stimulus Generalization is responding to stimuli similar to a reinforced one, Stimulus Discrimination is telling apart cues that predict different outcomes, and Contingency-Shaped Behavior is learned directly from the actual contingencies in the environment.
