Question Answered step-by-step This assignment is directly related to the video “Where Does… This assignment is directly related to the video “Where Does Language Reside In The Brain?” and its accompanying video resource “The Two-Brained Man”. In that video, there is pioneering research conducted by Dr. Michael Gazzaniga with Joe, a man whose corpus callosum was surgically removed. The corpus callosum is a bundle of ~200 million nerve fibers that connects the brain’s left and right hemispheres, allowing for the transmission of information between them. Removing the corpus callosum thus effectively prevents the brain’s two hemispheres from communicating with each other. Dr. Gazzaniga’s research explored in fine detail the effects that this removal had on Joe’s mental functions, including his linguistic abilities. First, give a brief summary of Joe’s backgroundwhy was his corpus callosum surgically removed? Second, consider the experiment that our narrator introduces as “a classic in brain research”, and which is described from the 2:50 mark to the 7:00 mark in the video. This is the experiment in which words briefly appear on one side of a computer screen, and Joe is then asked to either say the word aloud, or else to draw its meaning. This experiment provides a revealing window into where Joe’s linguistic abilities reside in his brain. Specifically, what does it show us about where Joe’s language-production abilities reside, and how does it show this? Third, this same “pronounce vs. draw” experiment gives us a slightly different picture of Joe’s language-comprehension abilities. Specifically, the results suggest that while Joe’s language-production abilities predominantly reside in just one hemisphere, his language-comprehension abilities are more even distributed across both the left and the right hemispheres. (Joe’s language production is “highly lateralized”, while his language comprehension shows more “bilateralization”.) How do the experiment’s results support this conclusion about Joe’s language-comprehension abilities? Arts & Humanities English LINGUISTIC 01:615:101 Share QuestionEmailCopy link Comments (0)
