A Guest Speaker Is Coming to Mr

A guest speaker is coming to Mr. Fisk's third-grade classroom, and he wants his students to treat the speaker with courtesy and respect. He decides to give his students 15 minutes of free time if they show appropriate behavior during the guest's visit. From the perspective of social cognitive theory, Mr. Fisk's reinforcement is likely to work only if his students:

A) Also experience intrinsic reinforcement for good behavior
B) Expect that this consequence will follow their good behavior
C) Have previously been directly reinforced for such behavior
D) Have previously been vicariously reinforced for such behavior
