refers to the allocation of responses to choices available on concurrent schedules of reinforcement. Rates of responding across choices are distributed in proportions that match the rates of reinforcement received from each choice alternative.

Matching Law

Explanation: The principle of matching law aims to explain the circumstances that gives rise to a particular response. It is a quantitative tool employed in experimental analysis for measuring rate response rate and relative rate of reinforcement in concurrent reinforcement schedule for two or more behavior. Matching law utilizes the principle that whatever an individual does is being triggered by precedence that is what has happened before. Matching laws are applied in conditions whereby two or more alternative responses are available, therefore, the ratio of response rate of the response is equal to the ratio of reinforcement yielded by each response.

rain should be the answer.

where is the rest of the question. this isn't making sense. can you upload a picture of the question?
