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?

Historically, researchers claimed that the left hemisphere was the dominant hemisphere where all higher brain functions, such as reasoning and problem solving, took place. The right hemisphere was generally viewed as having no special functions or capabilities. The current perspective on hemispheric specialization claims that the left hemisphere is better at verbal processing tasks, while the right hemisphere is better at nonverbal processing tasks. Research involving the effects of split-brain surgery is what propelled this change in perspective. Answer for E2020
