13、rtain behaviors. There are no clear answers yet, but two【C3】_schools of thought on the matter have【C4】_. As one might expect, the two approaches are very different from one another, and there is a great deal of【C5】_between proponents of each theory. The controversy is often【C6】_as “nature v. nurture

14、“. Those who support the “nature“ side of the conflict believe that our personalities and behavior patterns are【C7】_determined by biological and【C8】_factors. That our environment has【C9】_, if anything, to do with our abilities, characteristics and behavior is central to this theory. Taken to an extr

Proponents of the “nurture“ theory, or,【C12】_they are often called, behaviorists, claim that our environment is more important than our biologically based instincts【C1

16、3】_determining how we will act. A behaviorist, B. F. Skinner, sees humans as beings whose behavior is almost completely【C14】_by their surroundings.

17、havior. The social and political implications of these two theories are profound. In the United States, blacks often score below whites on standardized intelligence tests. This leads some “nature“ proponents to conclude that blacks are biologically inferior to whites. Behaviorists,【C18】_, say that d

18、ifferences in scores are due to the fact that blacks are often deprived of many of the educational and other environmental【C19】_that whites enjoy. Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the【C20】_to our behavior lies somewhere between these tw
