Fixed Ratio (FR) is a schedule of reinforcement where reinforcement is provided after a fixed number of responses. The ratio remains constant, meaning the individual must complete a set number of correct responses before earning reinforcement. This schedule often leads to high rates of responding, as individuals learn that a specific number of responses is required for reinforcement.
Example
A teacher uses a Fixed Ratio (FR 5) schedule, where a student receives a token for every five math problems they complete correctly. The student knows that after completing five problems, they will receive a token, which can later be exchanged for a reward. This clear ratio encourages the student to maintain steady work to reach the reinforcement.
