What is an example of a rewarding stimulus used in positive reinforcement?

A rewarding stimulus in positive reinforcement serves to increase the likelihood of a desired behavior by providing a pleasurable or satisfying consequence following that behavior. In this context, a paycheck or praise exemplifies a rewarding stimulus because it acknowledges and reinforces the individual's actions, encouraging them to replicate those behaviors in the future.

For instance, when an employee completes their work successfully and receives a paycheck, the financial reward encourages them to continue performing well in their job. Similarly, verbal praise can enhance self-esteem and motivation, making it more likely that the praised behavior will be repeated. Both scenarios exemplify positive reinforcement because they introduce a stimulus that enhances the individual's overall experience and motivation.

In contrast, the other options represent consequences that do not align with the concept of positive reinforcement. For example, a safety warning serves as a cautionary measure rather than a reward, a reprimand acts to discourage certain behaviors, and a loss of privileges imposes a negative consequence rather than providing a positive stimulus.
