What response cost method does Mr. Marley employ by docking minutes from extra recess when he has to remind students to be quiet?

Mr. Marley employs a response cost method with a group by implementing a system where he deducts minutes from the entire class's extra recess time when reminders to be quiet are necessary. This approach targets the collective behavior of the students rather than singling out individuals, thereby reinforcing the expectation that the group needs to maintain appropriate behavior to earn their recess time.

Using a group-based response cost can be effective in promoting accountability among students as they recognize that their collective actions affect the entire group's privileges. This fosters a sense of social responsibility and encourages students to help each other adhere to the rules to maintain their access to desirable activities, like recess.

The other concepts mentioned, such as individual response cost and negative reinforcement, focus more on personalized behavioral consequences and increasing desired behaviors through avoidance, respectively, while behavioral modifications refer to broader strategies to change behavior rather than specifically the response cost framework used by Mr. Marley.
