In summary, the right and left hemispheres have distinctly different cognitive functions. Two separate and unique ways of processing stimuli exist within each person. Both hemispheres receive and process sensory information from the surrounding environment and each hemisphere processes the information separately (Sousa, 2006; Vitale, 1982).
Although, the notion of localization of brain function emerged from early studies of brain-damaged individuals, recently, hemispheric asymmetry has been investigated by studies on normal people in a number of ways. Some of the techniques on normal people are similar to ones previously used in clinical populations (i.e., tachistoscopic presentation and dichotic listening technique), whereas other studies

In other words, left brain dominance can determine a higher level grammatical sensitivity than right brain dominance. This occurs because grammatical sensitivity requires analytic thinking and it is precisely in the left hemisphere where this kind of reasoning takes place (Piruad, 2008).
2.2.3.1. Empirical evidences on hemispheric dominancy
There is a rapidly growing literature on the role of brain dominancy in language learning and education. This part starts by outlining the results of the related researches conducted on this matter.
Regarding the issue of brain dominancy and students achievements, Jarsonbeck (1984) conducted a study to examine the effects of right-brain mathematics instruction on low achieving students. The results showed that more right-brain dominance students were in the lower achieving group, whereas more left-brain dominance students were in the higher achieving group. In addition, it showed that students in the control group, left-brain instruction, achieved higher scores if they were left-brain preference, whereas students in the experimental group, right-brain instruction, achieved higher scores if they were right-brain preference. The study indicated the importance of matching teaching strategies to student hemispheric

He reported that humanities students showed preference for the right-hemispheric dominance. Natural science students demonstrated a left-hemispheric mode, while social science majors showed preference for left-hemispheric dominance.” (p. 7)
In order to test the effects of hemispheric dominance upon course grades of undergraduate psychology students Gadzella (1995) conducted a study and claimed that there were significant differences between left-brain dominance and right-brain dominance groups with the left-brain dominance group obtaining higher course grades. The course grades did not differ significantly for the integrated-brain group compared to left-brain and right-brain groups.
Even though most of the literature suggests each of the brain hemispheres as dichotomies, Saleh and Iran-Nejad (1995) through the idea of hemispheric dominance suggests that brain hemisphericity acts on a continuum and it is not dichotomous. Some studies found that students taught through methods that matched their hemispheric styles achieved statistically significant higher test scores than when they were taught through other teaching methods (Jarsonbeck,
"Brainology: Transforming Students ' Motivation to Learn" is collection of informative text by Carol S. Dwecks, covering the concept of Fixed and Growth mindsets, along with the cause and effect for each. Dwecks opens the text with a researched idea that our brains are constantly changing throughout our lives, while learning and experiencing, followed by a question "Does this learning have implications for students ' motivation and learning?". Later showing that what students believe about their brains and source of intelligence, whether sought as being fixed or having the ability to grow and change, does have effects on their motivation and will to learn. Another question is asked, how do said mindsets work, and how might we be able to
Consequently, “western cultures [favor] the characteristics of left-side functioning, our educational system reflects that bias and is heavily weighted against those individuals whose physiologic makeup has granted them attributes of creativity, imagination, and fantasy” (Schmitt & Clemens, 1994, p. 133). Schmitt shares his journey from being known as an idiot to proving to the world he is brilliant, highlighting on moments of success and

The brain, in cahoots with the nervous and endocrine systems, controls our behavior, thoughts, and actions, involuntary and voluntary. Scientists have studied the brain and determined, to a reasonable extent, what regions of the brain control what skills. These studies of the brain have provided much valuable information about how injuries and any operations done to the brain can affect our behavior and ability to perform certain tasks. The brain is divided into 3 main areas, the forebrain, midbrain, and hindbrain. The hindbrain, located at the bottom of the brain, controls very simple basic functions of life.
In the sixth grade, I took a test to see if I was left- or right-brained. To my elementary eyes, the result of that quiz would be the truth from on high—a resolute word that would define the man to come as either analytic or artistic. Unfortunately, the oracle I sought gave me a perplexing answer. Much to my disbelief, my tallied score yielded a perfect split down the middle. Was I mentally ambidextrous or mentally challenged?
Studies show that we generally have a higher GPA and a higher IQ level. It is believed this because they use both sides of their brain, allowing them to process more information. Just as there are advantages of being a Southpaw, there are also disadvantages. These disadvantages make life really difficult for lefties.
The brain is the most complex organ in our body. It serves as the command center of the human nervous system. The brain is composed of different parts and functions that are dependent upon each other. The brain consists of two distinct sides: the right and left cerebral hemispheres. The side of the brain that endures damage will impact the function on the opposite side of the body and impairs mental capabilities.
Looking at the history of reflection on free will, it can be noticed that such concept was not known in the Ancient Greece. Albeit, Aristotle has shyly discussed about a concept of ‘’choice’’ (proairesis), however it is poorly connected with actual acts, let alone the power of free will. It can be argued that the Greek stoics somehow recognised the possible existence of free will, since they greatly attributed the necessity of defending our inner beliefs and morals, so that the human shall not inherently delve into seeking desires, not worry about them, as well as ignore the circumstances that are not dependant on us. Thus, stoicism attributed to the individual the necessity of being free from all external influences and defending their personal inner sentiments. The development of the concept of free will can be directly attributed and traced back to the late Roman stoicism, especially during the time of Epictetus, whose philosophical teachings and views were written down by one of his students.
I first developed an interest in the wonderfully interdisciplinary field of neuroscience in my freshman year of high school. That year, I was given the opportunity to conduct and construct a self-study research project regarding any subject falling under the umbrella of bioethics. I soon found myself immersed and enthralled by the nature of neuroscience as I studied brain imaging using functional Magnetic Resonance Imaging and its implication in the judicial system as lie detection evidence. My conclusion at that time was that the technology was too unreliable, too expensive, and furthermore unstandardized, and thus it would be an unethical and unviable evidence in a legal case. The next year, I was given the same opportunity, though this
But, is there any likely difference between males and females in poor-level spatial attentional processes and their consequences on greater-level spatial
One of the most prominent structures in the brain is the corpus callosum composed of approximately 200 million fibers that facilitate the sending and receiving of information between the left and right hemispheres of the brain. It allocates attention, efficiently stores and retrieves memories, and enhances language and auditory functions. This connection across the midline has been linked to creativity and intelligence, and as development continues throughout adolescence, becomes more crucial as task complexities increase. Irregularities in the corpus callosum have also been reported in several childhood disorders and could explain memory and oration difficulties
This study was ideal in the sense that if recall was wrong the next letter would appear unlike in Thompson, Kosslyn, Hoffman & Van Der Kooij’s (2008) study; but something this study did unwell was discard any participant who had more than one learning style, which could have changed the results. Mayer & Massa (2003) found no significant sex differences in learning styles, this was something this study did not take into consideration as gender was not used for the results. A positive aspect of this study was having an equal amount of trials for each rotation, like Bigelow & McKenzie (1985), as it can help with getting a true result. Searle & Hamm (2012) found that the brain can get confused easily because there are letters like ‘J’ that face to the left, when most face to the right, so when rotated or mirrored, one could assume that the ‘J’ is normal when it is the complete opposite, which should be considered in the
This suggestion works in accordance to the evidence that suggests that the brain is predisposed to have certain areas specifically designed for language processing and development. For example, Gazzaniga (1986) stated that language processing occurs in the left hemisphere of the
