Correlational Method

The human brain is a wondrous invention that has many scientists and researchers very busy to this very day. There are numerous qualities about the brain humans know about, yet there are still a great number of mysteries to the brain and how it functions left to be discovered and shared. Some facts scientists do know about the brain is that it is divided into to primary sections, called hemispheres. Each person has a left and right hemisphere of the brain. Each hemisphere is in charge of specific abilities, tasks, and functions. This paper will review what each hemisphere is responsible for and describe ways that each hemisphere is predisposed to learn.

The purpose of this paper is to evaluate the correlational method as a means for examining the relationship between functions of the left and right hemispheres. I will compare the performance of people with intact brains with the performance of so-called split-brain patients. In many ways, the brains of these two groups are very similar. 1a. The brain stem is found in the deepest part of the brain. The brainstem controls the automatic survival functions of the body, such as breathing. There are no differences between the function of the normal brainstem and the brain of a split brain patient. The brainstem will still supply the automatic survival functions of the body. 1b. The hippocampus is found in the limbic system along with the amygdala, the hypothalamus. The hippocampus is in charge of allowing the body to process information into memories. Without the hippocampus, there is no way for new memories to be created. There is no anatomical difference between the hippocampus in the normal brain and a split brain. 1c. The corpus callosum is found in the center of the brain. The role it plays as a part of the brain is it connects both the left and right hemispheres of the brain, allowing them to work and interact together as a whole system. The difference between the anatomy of the corpus callosum in a split brain patient versus someone without a

In the excerpt “Right Brain Rising”, Daniel Pink tells his experience in depth detail of an intriguing brain scan beneficial both to his curious mind, and the world of science. He then goes on to inform readers of the two distinct halves resting in our skulls; following up with the past inferiority associated with the human right brain, thought to be due to years of evolution. After acknowledging the disproved theory, Pink delves into information pertaining to psychology’s six

The other test held was an auditory test. The test was done in two different ways. One way was finding the objects in a bag that were mentioned verbally and the other was identifying the item reached by touch. This test’s results were also supporting the previous researchers’ logical conclusion about the left hemisphere ability of speech. It confirmed the right hemisphere’s ability of comprehending language and its ability of expressing it in a nonverbal way. During the test, evidently, the right hemisphere had no trouble identifying the unknown objects by touch as the left hemisphere did. Moreover, some three- dimensional drawings of the slit-brain patients, who were all right handed, developed much better drawings using their left hands compared with their right hands.

As shown in the chart, the split brain has a low correlation than the intact brain, which has a higher correlation. This proves that a person with a split brain cannot process information to the left and right. Face recognition is in the right side of the brain while vocabulary and reasoning in the left side of the brain. When comparing face and reasoning it only gave a low correlation same with face and vocabulary. Vocabulary and reasoning is in the left hemisphere, therefore, being a bit more stronger than the rest of the results. In the intact brain reasoning, vocabulary, and face are being processed to the left and right showing that they are laterized.

Using a real human brain, Dr. Taylor explained the separation of the brain’s right and left hemispheres. The two cerebral cortices are completely separate from one another, but maintain communication via the corpus callosum. She described the right hemisphere as a parallel processor, thinking in images and learning from body movement. The right hemisphere is responsible for gathering sensory input, in the form of energy, from the environment around us. The left hemisphere, according to Dr. Taylor, is a serial processor, interpreting the sensory information gathered by the right hemisphere. The sensory information is analyzed and categorized by the linear and methodical thinking of the left hemisphere. Dr. Taylor believes the left hemisphere is responsible for interpretation of the past and future, as well as, an individual’s self-awareness. The

The book starts with the Chapter Right Brain Rising describing hemisphere of left brain and right brain. According to Pink the left brain hemisphere is consistent of logistic, literal and analytic personal whereas right brain is for holistic reasoning, body language, patterns recognitions and emotions. He carefully pointed out that the term L-Brain

The results of this study show us the brain is not in fact symmetrical and the two hemispheres in the brain work in different ways. The left hemisphere is known to play the dominant role, which is in control of all complex behavioural and cognitive processes as for the right hemisphere it only plays a minor role. This report will further analyse how different the two hemisphers is the dominant side of the brain.

For many decades people have been considered to be either right or left side dominant in regards to brain function which came with defined roles such as “creative” or “analytical”. This thinking tends to be over-simplified as most people use their entire brains daily (Jensen, 2010). On the other hand people do use different parts of their brain for different tasks according to how they perceive those tasks.

In 1967, M.S. Gazzaniga studied the split brain in man. Gazzaniga wanted to study how the two halves of the brain functioned independently. Since it a little unethical to snip the peoples corpus callosums just for fun, it wasn‘t until doctors discovered that cutting the corpus callosum could actually cure severe epileptic seizures that it was possible for Gazzaniga and Sperry to study them. They found that the test subjects intelligence, personality, and emotions had not changed. We use each half of our brains for specific skills. Three different tests were designed to check mental capabilities. It was found that the left-brain is better at speaking, writing, reading, and math, and the right brain is better at recognizing

behavior of a person. Right and left hemisphere of the brain are working independent of

Left-right brain dominance is about the fact that the distinct hemispheres influence thinking. The left hemisphere is associated with logical, analytical thinking and a linear approach to problem solving. The right hemisphere is associated with creative, intuitive and value-based thought process. It is important to note that everyone uses its both hemispheres, but to varying degrees. Four quadrants of the brain, related to different thinking style, have been identified:

The brain is the command center for the body’s nervous system. The cerebrum makes up 85% of the brain’s weight, and has 86 billion nerve cells (called neurons) and billions of nerve fibers (called axons and dendrites). The neurons are known as the gray matter of the brain and the axons and dendrites are known as the white matter of the brain (Tanya Lewis, 2015). The brain is divided into two hemispheres; the left and the right hemisphere. The left hemisphere is responsible for words, logic, numbers, analysis, lists, linearity, and sequence. It also controls the right side of the body. The right hemisphere is responsible for creativity; color, imagination, daydreaming, holistic awareness, dimension, and it controls the left side of the body (Boundless.com, 2015). Severe trauma to a part or all both of these hemispheres can possibly result in a coma. A prolonged coma longer than a year transitions to a vegetative state. A vegetative state longer than 3 months can lead to death. In the event the patient becomes brain dead they are unable to make autonomous decisions for themselves.

The human brain is divided in two different symmetrical parts, the hemispheres, which are connected by the corpus callosum – this connection enables us to engage in higher cognitive processes (Rogers, Zucca & Vallortigara, 2004). Evolution provided us with the capacity to benefit from lateralization, allowing us to perform well while involved in two completely different tasks simultaneously. Furthermore, the plasticity of the brain makes it easy to thrive in extreme situations, such as having the two hemispheres disconnected or even having one hemisphere removed. In such cases the nervous tissue will adapt itself and reach its maximum potential, so that the person can survive and retain consciousness. This ability is more pronounced in children, in which the reorganization of the cerebral cortex after traumatic surgeries such as hemispherectomy is an indication of the possibility of recovery and cognition with just half of the brain.

The brain is split into the right hemisphere, and the left hemisphere. The right side of the brain controls the muscle on the left side of the body, and vice versa. Studies show that people with a higher dominance of the right side to the brain tend to comprehend visual
