People have wondered for a long time how their personalities and behaviors are formed.It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive.
Social scientists are, of course, extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behaviors. There are no clear answers yet, but two distinct schools of thought on the matter have been developed.As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory. The controversy is often referred to as nature/nurture .
Those who support the "nature" side of the conflict believe that our personalities and behavior. patter, ns are largely determined by biological and genetic factors. That our environment has little, if anything, to do with our abilities, characteristics, and behavior. is central to this theory. Taken to an extreme, this theory maintains that our behavior. is predetermined to such a degree that we are almost completely governed by our instincts.
Proponents of the "nurture" theory, or, as they are often called, behaviorists claimed that our environment is more important than our biologically based instincts in determining how we will act. A behaviorist, B.F. Skinner, sees humans as beings whose behavior. is almost completely shaped by their surroundings. The behaviorists' view of the human being is quite mechanistic; they maintain that, like machines, humans respond to environmental stimuli as the basis of the behavior.
Neither of these theories can yet fully explain human behavior. In fact, it is quite likely that the key to our behavior. lies somewhere between these two extremes. That the controversy will continue for a long time is certain.
According to the passage, people have wondered for a long time
