Some researchers consider developmental psychology an applied research topic because
(A) it is more easily applied to people's lives than research such as behaviorism.
(B) researchers apply findings and theories from other areas of psychology to the specific topic of human development.
(C) it is more commonly studied by a graduate student rather than an undergraduate because of the applications for other research.
(D) doing original research in this area is difficult, so most of the research is about application.
(E) pure research is difficult to gain support for, especially when a researcher needs to recruit children as participants.
