Joe's boss allows him to leave early while others must stay to clean the store because he offers customers excellent service during his shift. this is an example of which of the following?

positive reinforcement

negative reinforcement

punishment

classical conditioning

Positive reinforcement.

Explanation:

Positive reinforcement is a method in psychology, that refers to the introduction of a desirable or pleasant stimulus after the behavior.

Desirable stimulus reinforces the behavior, which makes it more likely that the behavior will reoccur in the future.

In this case, Joe's boss allowed him to leave early because he did a good job that day, so he got to finish his shift early and enjoy his free time. His boss is hoping that he will continue to do good work due to his generous act.

Explanation:

Negative reinforcement is used in behavioural psychology. The term was used by Skinner, the father of operant conditioning. Through this theory, Skinner said that we respond to daily stimulus and our behaviour is a result of that situations.

In addition, Skinner used technical terms like negative and positive reinforcements. He defined negative reinforcement as a reinforced behaviour by avoiding a negative stimulus or situation, knowing negatives situations as those that make people uncomfortable.

Therefore, Joe avoided a negative situation, an uncomfortable outcome, because he could leave early; not being able to leave is a negative outcome for him. That's why this is an example of negative reinforcement.
