As the babysitter for fifteen children, you must use a multitude of tactics in order to contain them and follow the three rules the mother has provided while she is out of town. For the first rule, she has allowed the children to play with any toys they desire, but they must clean their playroom before their bedtime. For this particular request would be executed through positive reinforcement, which would intel immediately revealing the process of cleaning up their toys before they go to sleep will result in warm cookies and milk before bedtime. The second rule of the mother was for the children to share their toys with each other. Although this is a difficult trait for kids to possess, it would be best brought about by using negative reinforcement.
