Mrs. Brown is using which type of reinforcement to motivate Sally to complete her work on time?

In this scenario, Mrs. Brown is employing extrinsic reinforcement to motivate Sally to complete her work on time. Extrinsic reinforcement involves providing rewards or incentives that are external to the task itself. This could include praise, tokens, privileges, or other tangible rewards that encourage the desired behavior—in this case, timely completion of work.

When using extrinsic reinforcement, the focus is on the outcome of completing the task rather than the intrinsic satisfaction that may come from the work itself. This approach can be particularly effective in educational settings where students may struggle with motivation or where immediate rewards can help cultivate good habits.

While positive reinforcement is similar, it generally emphasizes the addition of a favorable outcome immediately following the desired behavior, which may or may not be extrinsic. Intrinsic motivation focuses on the internal satisfaction or enjoyment derived from the task itself, and social reinforcement pertains to the encouragement or approval from peers or teachers. Therefore, extrinsic reinforcement is the most fitting choice in this context, as it highlights the external supports that Mrs. Brown is likely providing to motivate Sally.
