Abstract:

Since the time of classical Greece, we have been accustomed to viewing humans as both thinking and feeling individuals. The dichotomy of cognition and affect is so ingrained in Western thought that it seems a natural one; the two elements have seldom, however, been deemed equally important in the scientific community. During the nineteenth century and early twentieth century, psychology gave primacy to affect; humans were thought to be at the mercy of various drives and passions. As behaviorism became more domiúnant in the field, affect was discounted; indeed, there were those who wished to exclude affect from scientific study altogether. More recently, with the ascendancy of cognitive psychology, humans have been viewed as problem-solvers whose thinking processes operate rather like a computer. Often in such a view, affect is seen as “a regrettable flaw in an otherwise perfect cognitive machine” (Scherer 293). But most researchers who study human behavior and human nature agree that the views of both extremes—emphasizing only affect or only cognition—are undesirable.
