Answer: b. Positive reinforcement and punishment
Step-by-step explanation:
Positive reinforcement is a way of encouraging certain behavior by adding something pleasant when the subject does something that it desirable or a stimulus. James giving the employees some incentives (something pleasant) when they meet required targets (something desirable) is therefore positive reinforcement.
Punishment on the other hand, refers to taking away something pleasant in response to the subject doing something that isn't very desirable. In this scenario, James would take away the incentives (pleasant) in response to the employees behaving unprofessionally (isn't very desirable).
