Final answer:
A fixed ratio reinforcement schedule reinforces a response after a predetermined number of responses, leading to a high rate of response with a short pause after reinforcement.
Step-by-step explanation:
The pattern of intermittent reinforcement in which responses are reinforced after a set number of responses is called a fixed ratio reinforcement schedule. This type of reinforcement schedule encourages a high rate of responding, with a typical pattern that includes a short pause following reinforcement. For instance, in a work scenario, a salesperson might receive a commission after every fifth sale, prompting a rapid series of sales efforts followed by a brief break before resuming the next set of efforts.
