Susie, Sally, and Serena are roommates. Susie and Sally are neat freaks, but Serena is a slob. Both Susie and Sally want to use reinforcement to get Serena to start picking up her messes. Susie wants to use positive reinforcement as her technique, and Sally wants to use negative reinforcement. Devise a plan for Susie and another for Sally based on each person's reinforcement style.
