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:

Historically, hemispheric specialization was often described as a strict division: the left hemisphere was associated with language and logic, while the right was associated with creativity and nonverbal abilities. The current view is more nuanced: some functions are lateralized, but the hemispheres work together, and many abilities involve networks on both sides of the brain. Split-brain research helped reveal specialized functions in each hemisphere, while later brain-imaging and other studies showed the extensive cooperation between them.
