Final answer:
Option (2), Andy's act of chastising for poor performance is an example of punishment, as it aims to decrease the likelihood of poor numbers by introducing an unpleasant response.
Step-by-step explanation:
When Andy chastises chefs and GMs on poor numbers, he is engaging in 2) punishment. In the context of operant conditioning, punishment is a process that decreases the likelihood of a behavior by adding something unpleasant in response to the behavior, or taking away something desirable.
Since Andy's chastising is a response aimed at decreasing the occurrence of poor performance, it is an example of punishment. Chastising does not involve adding something pleasant (positive reinforcement), increasing a behavior (negative reinforcement), or adding something desirable (positive reinforcement).
