Your assistant has started coming in late to work with a take-out coffee in hand, and is frequently on her personal phone engaged in non-work discussions. She is first out of the door at the end of the day and resists all requests to 'go the extra mile'. However, the work that she does is excellent although she is late in submitting it. Provide one example from each of the reinforcement concepts (positive reinforcement, negative reinforcement, punishment and extinction) and discuss how you would address her performance. Explain how each would work.
