The Central Executive drives the subsidiary system. It is the main component of the Working Memory Model and its main role is to direct attention to particular tasks, determining at any time how ‘resources’ are allocated to tasks. The resources described are the three subsidiary systems, also known as the three slave systems. Although directing these three subsidiary systems it has a very limited capacity and therefore cannot attend to too many things at once although if any of the systems become overworked it will help with some of the workload. To prove that the Central Executive was the driver behind the subsidiary systems, evidence was needed, Bunge et al (2000) found evidence for the Central Executive and used FMRI scans to see which part of the brain were most active when participants were tasked with reading a sentence and recalling the final word in each sentence. He believed that activity in the Central Executive should be increased when an individual has to perform two tasks simultaneously (dual-task) rather than one after the other (single-task). His results from his…
Using an fMRI scan, Bunge measured brain activity and found that, unsurprisingly, there was more when carrying out a dual-task. This showed that increased attentional demands are reflected in brain activity.…

Split brain patients lateralize functions in their brains to either side of the brains while intact brain patients utilize both sides of their brains. A group of 20 subjects were tested, 10 split brain and 10 intact brain patients. We gave these subjects three exams, a vocabulary test, a logical reasoning task and a face recognition task. We found that split brain patients have a lower correlation between these exams compared to those of an intact brain. If we were to replicate this exam we will receive roughly the same numbers, but if done so more patients to the study group will give a better understanding and better results.…
The human brain has perplexed the minds of philosophers since the age of the ancient Greeks. In the late 1800s, the study of the brain-psychology-became its own discipline independent from philosophy when the scientific method was employed to study the underlying mechanisms of the psyche. Although the original research produced by the first psychologists was widely subjective and biased, it helped to pave the way for serious research conducted later in psychology's history.…

Mead & Hampson (1996) developed a study involving the divided visual field paradigm and a phonological rhyme/non-rhyme task to test the speed and accurateness of either side of the brain. This study was used to investigate functional asymmetry between the left and right hemispheres in phonological processing. The research was taken out equally on 15 male and 15 females London Metropolitan University students ranging from ages 18 – 35 years old. They were all specifically chosen to be right–handed and had English as their first language thus providing a fair experiment to see whether our left hemisphere (left side of the brain) or the right hemisphere is faster and more accurate. In conclusion using the mean and standard deviation to determine our hypothesis, it was calculated that the left hemisphere had a higher mean and standard deviation score compared to the right hemisphere.…

"The southpaw's secret semantics" article written by Shannon Brownlee, emphasize that there are different learning capabilities between the left-handers people and right-handers. According to series of research done by Beaver and other researchers, they have determined that handedness is the result of which hemisphere of the brain has dominance. They have suspected for a long time that language is conceived differently for left and right handed people. There have been many arguments over whether language is the result of environment or genes. Beaver also found that righties from left-handed families rely mostly on associations and memories to understand language and righties from right-handed families. Results from one of Beaver's experiments made linguists' believe even more that the rules of grammar are stored in the left hemisphere of the brain, and associations and memories that words evoke may be shared by both hemispheres. Researchers have also found that damage to the left side of the brain often results in partial or complete loss of power to use and understand word. However, left-handed people seem to suffer less from this kind of damage, and they may be more crippled by an injury to the right side of the head. To conclude, in Beaver's view, the genes for right-handedness predispose the brain to concentrate linguistic rules in the left hemisphere, but linguistic associations more equally. I will used this study in my research to provide evidence for different learning capabilities between left-handers and right-handers people. And how the human brain function.…

This showed that the left hemisphere was better in analytical and verbal tasks than the right hemisphere and that the right hemisphere, although mute, can perform space perception tasks for example map reading. The right hemisphere also controls the emotions in the mind, although only being able to produce simple words and phrases.…
