Some child interaction guidelines, which have long been followed by both parents and teachers, derive from the popular notion that reward and punishment effect behavior. Thus if a child is punished for misbehaving they are less likely to do so in the future. A belief which sounds reasonable but is not.
As psychologists have long known, behavior modification work with dogs but not cats, with those of severely limited intellect (since it simplifies their environment) but not those of near normal and above intelligence, and for inhabitants of tightly controlled environments such as prisons. It does not work with others since humans are a thinking species.
Moreover, children are reasonable and want to develop into adults. Thus if asked to do something by their parent or teacher they usually will though being less likely to do so if they are hungry or tired or ill or troubled, or unable to do what is asked for a reason which may make sense to their immature mind but not to others.
Thus, apart from emergency situations involving harm or danger, explaining why a child should do something will usually gain their cooperation. If not it will be for one of the above reasons in which case they will be behaving like similarly afflicted adults.
