A clinical psychologist wants to determine whether a reinforcement-based intervention improves a client's self-care habits. She tracks two behaviors — frequency of teeth-brushing and frequency of bed-making — during an initial observation period. She then introduces the reinforcement intervention for both behaviors at the same time and observes that both behaviors increase simultaneously. This procedure allows her to rule out the possibility that an outside event, rather than the intervention, caused the improvements.
