ABSTRACT
Deviant children display their problem behaviors in a variety of environmental settings. A child referred for treatment because of unusual behavior may produce this kind of behavior in his home, his school classroom, his playground, and perhaps on the streets of his city. In addition, deviant child behavior may occur in several subsettings within a particular setting. For example, the negativistic child may be negativistic at bedtime and at mealtime, but he may be quite cooperative at other times (of his day) at home. Also, the same child at school may be considered difficult to manage during the arithmetic lesson but no problem during the social studies lesson.
