From the book of One Brain, Two Minds , some assertions are seen in the book. This hypothesis and claims tend to propose the relationship present between the variables. As the author suggests that right-handed are scientific and more logical than the left-handed people; this is the one that whose left-hemisphere is dormant. The left brains and alright brain are according to the author, and his test proved that the left hemisphere would receive the visual data leading to the patient being able to identify and recognizes faces and images.
The books definition and description of the hypothesis that illustrates how the dependent and independent variables relates is partly explored as each part of the brains is responsible for countless roles. Again the brain's function cannot be distinguished by the actions and effectiveness of the patient ability to differentiate familiar objects. This can be true, but some other activities might fail to get a similar positive response. The two sides of the brain are different regarding what they do, the functions and process they control.
Delegate your assignment to our experts and they will do the rest.
As the book claims that people that are left handed are logically better at reasoning that right-handed people; this is somewhat bias or lightly grazing the facts. Through legitimate research and scientific research, there has been documented evidence that the specialization and difference of the right and left brain is somewhat not different as each side can efficiently execute similar takes, the only difference seen from this experiment was that each side does the same process at a different speed and pace. One side finds it more comfortable to execute a task than the other, though one takes much longer than the other.
From the scientific finding produced in the research, ‘split-brain’ as tested through visual data, this data was identified by the patients who latter solved all logical problems with ease (Corballis, 2007). In correcting the Corpus Callosum by surgical methods, the epileptic seizure ceased to continue and at the same time regained their normal abilities. The book as informative as it relied on and used a lot of biological terms; the brain nervous system is one issue that profoundly impact any cognitive development either through surgical treatment or growth. As the books explore how both sides of the brains are different, it should have explained how through development and treat the endocrine system is affected, how does the cognitive and behavioural part of the patient before and after the brain altered, is the time necessary for the healing or does result immediately come. The book also addresses claims through the use of operational definition in cases where and the response would be required.
The book needed to incorporate a lot of terms about the split- brain personalities and attributes. Their definitions would have made it easier for the reader to get a clear understanding of the nature of case and study and experiment being done. The split-brain evidence that proves the consciousness of each part of the brains is not possible to establish. There has been a lot of over criticism that demonstrates with proof that the brain has only one consciousness and not two as claimed by the book. The evidence is coming from research-based processes such as the split brain syndrome. Cases where large subsystems in the brains fail to communicate with each other. The book is also braised in that there are no methods of separating or isolating the subsystem from living people without crossing moral grounds.
To further illustrate the flaws and errors in the methods applied in the book, I would place tow patient who successfully underwent the complete Callosotomy. Test one would have each patient is put in front and shown different objects set in different locations. They would be requiring spotting the object and pointing to where it was. The other test would need them to names each object they had seen. This would be hard for many split-brain patients. This test would seek to determine where the patient is doing much better on the left or right side.
The result from this experiment would indicate a correct infer to my hypothesis that consciousness is not found on split braincases as each person will find each object but take longer to come to an answer. One Brain, Two Minds, is a book that seeks to enlighten and pinpoint ideas and proven evidence that can be assumed but to an extent not justified.
