Otago, New Zealand, people whose job is quite simple and requires little thought is actually likely to lower the IQ (Intelligence Quotient). So that IQ does not go down, it is recommended to do not be lazy and not give up if you think finding a job is complicated.
Many people think IQ is a genetic trait, but a body of research indicates a person’s IQ can be increased or decreased over the years.
IQ can be increased gradually or rapidly, after at least do cognitive training for several weeks. Increase in IQ because this training is usually not immediately understood by a person. But if cognitive training can then be left to fade again after a few months.
Studies have been conducted for 30 years at the National Institute of Mental Health found people whose work involves complex relationships, setting up a complicated system or deal with a difficult person or problem, then the results tend to show better IQ test from time to time.
In contrast, tests on a number of people whose job is quite simple and requires little thought is actually likely to be lowered IQ. The results of these studies have been published in 1999 in Psychology and Aging.
“When the researchers at the University of Hamburg who perform intensive training on 20 young adults for 1 month. The researchers found increased gray matter in the brain corresponding in 7 days after training begins. Gray material shrinks when training is stopped,” said the researchers as reported from FoxNewsHealth.
The results of these studies have been published in 2008 in PLoS One.
IQ tests do not measure abilities such as creativity, common sense or social sense. IQ tests only assess the various types of knowledge and skills, including abstract reasoning skills.
The increase in the value of abstract reasoning is the main reason the average IQ scores have risen about 3 points per decade since the 1930s, according to a study by James Flynn, a professor emeritus of political studies at the University of Otago, New Zealand.
In a recent study, a total of 33 students in the UK are given IQ tests and brain scans at age 12-16 years and observed again after about four years later by researchers from the Wellcome Trust Centre for Neuroimaging at University College London. About 9 percent of students showed a significant change of 15 points or more in IQ scores.
“On a scale where the value of 90-110 is considered average, a student’s IQ rose 21 points from 107 to 128. This means the student has been raised from 68 to 97 percentile compared to other students the same age. However, the value of other studentsdecreased from 114 to 96. Changes in a person’s IQ score is often discussed as a result of measurement error or the subject being tested was having a bad day. But the MRI in this study suggests that there are changes in gray matter regions in accordance with fluctuations in the skills of children children, “said Cathy Price, a professor of cognitive neuroscience that has been published in Nature.
Despite the small sample size, but this study attracted wide attention because it can show how changes in IQ scores can be reflected in the actual shift in the structure of the brain.
