Multitasng And The Brain: The Smarter Brain

The body gets ride of water through sweating, urinating and even breathing. Therefore, it is a job to keep the water from running out. Just by losing only a percent of the body’s normal water need, dehydration by just one percent cause mood swings, lack of concentration, and headaches. So with the brain consisting of the most water, its in the best interest of any person to keep it working.

Before moving on to the Modern-era of intelligence and the theories behind where it is going, we should also discuss the physiological/biological theories behind brain development and intelligence. Why? Because the world we are exposed to now has altered it much.

My claim is, is it true that humans only use 10% of their brain? No, we do

We can watch TV and look through social media news feeds on laptops while reading texts on smartphones. With all the multitasking it could be shrinking the structure of our brains. According to new research from the University of Sussex, people who use cell phones or other devices tend to have a less gray-matter density in parts of the brain versus teens who use one or more devices at a time. “Published in the journal PLOS One, the research is the first to reveal links between multitasking on different media devices and brain structure” (Keating). "Media multitasking is becoming more prevalent in our lives today and there is increasing concern about its impacts on our cognition and social-emotional well-being, says Sussex neuroscientist Kep Kee Loh (Keating)”. The researchers asked 75 healthy men and women how often they divided their attention between different social media devices, which included sending a text or listing to music while doing other stuff. “The participants were given brain scans, which showed that, compared with people who used one device at a time, this group had a less dense gray matter in the cortex which is the part of the brain that is involved in processing emotion” (Keating). Researches aren 't sure whether people with less gray brain structures are more likely to be good at multitasking or if the multitasking causes the gray structures to shrink. Other studies found that learning how to juggle and learning map routes increased the gray area in

Task switching is a hallmark of executive control, reflecting the flexibility of the cognitive system in adapting to dynamic situations. But this flexibility comes with a cost. People are slower and less accurate at switching than at repeating tasks. Some researchers argue that this switch cost reflects task-set reconfiguration: changing the existing task set—a specific configuration of the cognitive system—to perform a different task (Monsell,

This paper explores a published article that reports on results of Task Switching and Their Effects on Cognitive Processes with in an individual’s mind when asked to do something. This article addresses the shifts in between cognitive tasks, the reaction time and error time based on the task switch. This article also addresses how to decrease the chance of error by giving a chance of having an individual prepare beforehand. This paper will examine Monsell’s (2003) research in relation to how Task Switching is fully understood and what effects on the brain for the individual switching task and its cognitive process. As well as the analysis of participants which conducted this experiment and the materials that were used for this experiment. In this analysis there was 100 total trials where 50% contained Odd/Even trails and the other 50% contained Magnitude trials. All the trials were randomized and the participants pressed the correct key when the intended targets were displayed in the middle of a PC screen. There was a significant difference between the one independent variable and the two dependent variables.

The cerebrum is considered to be the largest part of the brain. Split in two parts called the left and

The concept that we are capable of multitasking is faulty. As human beings we have convinced ourselves otherwise. We often attempt to do many things at once when we are short on time and have much to do. Unfortunately the truth is that this is not optimal for creating or doing anything properly.

In this paper, I will argue that IQ increases aren’t solely due to the increase in abstract thinking.

Twin studies, for example, show the importance of environmental and genetic influences for traits, phenotypes, and disorders. We can have twins raised in different environment, which will show that environment plays a big role in a person’s life and is not genetically fixed. Thus, intelligence is not fixed as naturists assume it is. In the Jewish example above, IQ tends to be higher in Jewish communities because children are taught math and analytical skills at a young age, which is one of the biggest factors that the IQ Test tests on. Even more, The Bell Curve assumes that IQ differences are biologically fixed. But research evidence proves this wrong by showing (a) with each year of education the IQ scores rise by 2.7-4.5 points, (b) offset of school causes the IQ score to drop by 5 points, (c) IQ scores decrease during summer vacation, and (d) racial prejudice causes people of color to have lower IQ scores compared to whites.

There is a theory in psychology, called the Flynn effect that basically shows that each generation is roughly 10 IQ points higher than its immediate predecessor. According to this theory, if someone was born with an average IQ in the 1940s, the IQ change will have been so drastic in the time between then and now, that they would actually be found to be mentally impaired by todays standard of IQ test. Although only discovered in the 1930s, it is widely accepted that this has always been occurring. Through lessons taught by older generations and evolution in brain ability, each generation is ability to comprehend and think in ways that previous generations largely cannot. Of course there are exceptions but the exceptions are the geniuses who

In the study done in Friedman’s article, he says “...we can clearly enhance learning, even if mental gymnastics won’t make us smarter,” proving that although brains may not increase intelligence, they can maintain and continue to learn. Also, back to the beginning statement of “people exercise muscles,” in another study done, scientists found that doing exercises actually improved the growing of neurons in the brain due to a protein called “BDNF” being secreted (Friedman). BDNF improves memory, which would improve fact recollection in turn; most people may mistake fact and memory recollection for intelligence. Really, the only way people can prove that they get smarter depends on which definition they look at in a

This fact was proven by a study done by Harvard researchers. The study was relatively simple. The researchers gathered together 29 parents and their four year olds. The children were then asked to complete a vocabulary test. After the test was completed, the children were randomly split up into two separate groups. One group was designated to take music lessons for a year, while the other took visual art lessons for a year. When the year was up, the children were tested on cognition, vocabulary, math, and spatial tasks. These tests were chosen because they are more representative of intelligence than a simple IQ test. The students who had taken music lessons for a year performed almost identically to the students who had not taken any music lessons. The only difference was that some of the music-lesson students performed marginally better on one of the spatial

Performing physical activities whiles dehydrated can be quiet dangerous, it can cause you to faint and maybe even temporality shut down.
