Compare the historical view on hemispheric specialization with the current perspective of hemispheric specialization. What type of research occurred to propel this change in perspective?

Answer:

The historical view often treated the hemispheres as having sharply divided roles: the left was described as logical and verbal, while the right was described as creative and spatial. The current view is that the hemispheres have relative specializations, but they work together in most complex tasks; neither hemisphere is exclusively responsible for a broad kind of thinking. Research on people with intact brains—including visual-field and listening studies, as well as brain-imaging research—helped reveal these differences and showed that specialization is not an absolute division.
