Matching Law
A quantitative principle stating that the rate of behavior allocation matches the relative rate of reinforcement.
Full Definition
The matching law describes the mathematical relationship between choice behavior and reinforcement schedules, proposing that organisms distribute their behavior across alternatives in proportion to the relative rates of reinforcement obtained from each option. Originally formulated by Richard Herrnstein, this principle has been extended to understand complex human behaviors including treatment adherence, lifestyle choices, and health-related decision-making. In behavioral medicine, the matching law helps predict and modify choice behaviors by understanding how different reinforcement contingencies compete for behavioral allocation.
Usage
Usage note: Often referenced in quantitative behavior analysis and choice research contexts.
