Read the scenario below and answer the question that follows.Duke is practicing his spelling in the classroom. Duke is going to receive reinforcement after six demonstrations of the target behavior, which is spelling a word correctly. Which of the following statements is true?
Answer
A
Duke is on a fixed-interval schedule of reinforcement.
B
Duke is on a variable-interval schedule of reinforcement.
C
Duke is on a fixed-ratio schedule of reinforcement.
D
Duke is on a variable-ratio schedule of reinforcement.
Explanation
Reinforcement is delivered after a set number of target behaviors: six correctly spelled words. A schedule based on a fixed number of responses is a fixed-ratio schedule, so the correct statement is “Duke is on a fixed-ratio schedule of reinforcement.” Interval schedules depend on time passing, not on a required number of correct responses.
