Read the scenario below and answer the question that follows.Harrison sends an e-mail to his boss. Harrison expects a response within five minutes, but he can’t help himself and checks every 30 seconds. After five minutes, a replying e-mail is delivered just as he expected.Which of the following statements is true?
Answer
A
Harrison is on a fixed-interval schedule of reinforcement.
B
Harrison is on a variable-interval schedule of reinforcement.
C
Harrison is on a fixed-ratio schedule of reinforcement.
D
Harrison is on a variable-ratio schedule of reinforcement.
Explanation
A fixed-interval schedule reinforces a behavior after a set amount of time has passed. Harrison receives the reinforcing reply after the predictable five-minute wait, so this is a fixed-interval schedule of reinforcement. Checking every 30 seconds does not change the schedule into a ratio schedule, which depends on the number of responses.
