“The study, which finds that the right parietal lobe is responsible for dyscalculia.” Dyscalculia makes math hard for individuals who have this disorder, and about 5% of the population is affected by dyscalculia. Researchers have induced participants who usually find math easy, with dyscalculia making math hard and taking longer for them to do. The right parietal lobe was knocked out for a few milliseconds and because of that it took the participants longer to react to the math problem. “This provides strong evidence that dyscalculia is caused by malformations the right parietal lobe and provides sold grounds for further study on the physical abnormalities present in ’ dyscalculias’ brains.” The study was to test how people with dyscalculia and people induced with it would process numbers, and it was found that both took a longer reaction time processing the numbers. The study had induced participants who normally found math easy with neuron navigated transcranial magnetic stimulation (TMS) to stimulate their brains, and the test was conceived of questions to compare a number do to physical and numerical value. The study had found the parietal lobes are responsible for math calculations. The importance of this article shows that the 5% of the population suffers from dyscalculia and it affects their math skills. To psychology this shows that by finding that dyscalculia is caused by the right parietal lobe, there can be a cure for dyscalculia. Psychology benefits from this research because it gives reasons for “further study on the physical abnormalities present in dyscalculia’s’ brains.” This impacts everyday life in math class, if a person is not doing well it could be because the person has dyscalculia or that there is trouble in the person’s right parietal lobe. Then the person can get special help or find a cure to help them do better in math. "Math Hard?"* Sex Difference On Spatial Skill Test Linked to Brain Structure

The overview of this article was about how men and women differ of spatial skill test due to the parietal lobe. UI researchers found that the difference on how women and men differ on the spatial skill test is due to the surface area of the parietal lobes. For women the parietal lobe has a thicker cortex, and more “grey matter”, making women not due as well on the test. Tim Koscik (the head of the research at UI) stated,” This study represents the first time we have related specific structural differences in the parietal lobe to sex-linked performances on a mental rotation test.” The study included 38 women and 38 men, all of whom were right-handed except for two men and matched age, education, IQ, and socioeconomic upbringing. The study found that about 10% differs between men and women in the parietal lobe surface area; women have 40 square centimeters, while men having 43 square centimeters. The conclusion is that men and women “perform tasks differently” says Peg Nopoulos, M.D.  The importance of this article shows men and women differ in spatial skills tests and why they differ. In psychology this tells that they differ due to the parietal lobe, and makes it understandable in psychology and shows how it relates to psychology too. Psychology has to determine whether or not the spatial skill test difference is due to nurture vs. nature; whether it depends on upbringing between men and women (nurture) or biology of the person (nurture). The impact of this research shows that it makes it harder for women then men to picture 3-D objects in space. This article also relates back to “Finding Math Hard? Blame Your Right Parietal Lobe” not being able to see things 3-D would make geometry and math hard, especially for women according to this study and this experiment. "Sex Difference"  The overview of this article was about how the parietal lobes are affected for the worse when a person tries to stop drinking but is an avid smoker. The article states that,” parietal lobes are involved in aspects of attentional regulation and visuospatial processing.” The more a person smokes and drinks the more likely it is that the person will suffer in the frontal and parietal lobes. There was a study done by Anderson Mon and his workers that measured the frontal and parietal lobe dysfunction affected by recovering alcoholics that smoke. There were 19 non-smoking participants that were alcohol-dependent, 22 smoking alcohol-dependent participants, and 28 non-smoking light drinking participants. The study found that the alcohol dependent participants who did not smoke had made recovery from alcohol in five weeks, as compared to the alcohol dependent participants who did smoke who showed no progress for recovery. Mon stated, “prolonged and excessive alcohol consumption is bad for your brain, but a combination of alcohol with smoking is worse. ”  The importance of this article shows frontal and parietal lobes can be damaged from excessive drinking and smoking. Psychology can benefit from this by trying to get patients to stop drinking and smoking, so that the frontal and parietal lobes can function properly. The other importance of this article can show psychology that smoking and drinking together is the worst combination for your brain to work correctly. The impact of this research shows that people who smoke and drink will most likely have troubles in their frontal and parietal lobes. This relates back to math; people who smoke and drink therefore damaging their frontal and parietal lobes, have a greater possibility of having troubles in math from this. "Smoking and Drinking"
