Final answer:
A fixed ratio reinforcement schedule provides reinforcement after a specific number of responses, motivating a high rate of response from the individual.
Step-by-step explanation:
The pattern of partial reinforcement in which reinforcement requires a set number of responses is called a fixed ratio reinforcement schedule. In this schedule, a predictable and specified number of responses must be made before a reinforcement is given. An example might be a sales commission structure where an employee receives a bonus for every set number of sales they make, regardless of the time interval between sales or the quality of the products sold. This method encourages a high rate of response, as the reinforcement is directly contingent upon the quantity of responses.
