RECENT RESEARCH RELEVANT TO IQ

More politically-correct inability to see the obvious

Both sides of the debate below seem to be assuming that it is upbringing that is responsible for the difference in children's intellectual achievement -- when all the research shows that genetics is the major influence -- with upbringing of negligible importance. Smart people tend to get rich and pass on their smart genes to their children -- and that is all there is to it. The finding is in fact just another confirmation of Charles Murray's well-known scholarly work that showed a strong link between social class and IQ. To be very blunt about it, the poor tend to be dumb and the rich tend to be smart. There are of course exceptions but that is the general tendency that is being detected below

A CHILD’S reading age and ability to count develop a month earlier for every extra £100 a month in family income, according to a government-funded study to be unveiled this week. Gaps in the development of children from different socio-economic backgrounds appear by the age of three and widen until 14. The findings, written by a panel chaired by Professor John Hills, are based on the Millennium Cohort Project which tracks 19,000 youngsters.

It will fuel divisions between Labour and the Tories over the link between a child’s prospects and household income.

Harriet Harman, Labour’s deputy leader, said last night: “[The report] provides an incontrovertible basis for us to move beyond inaccurate assertions made by the opposition ... David Cameron says that the differences in child outcomes between a child born in poverty and a child born in wealth are statistically insignificant when both have been raised by confident and able parents. “But what he fails to say is that you can’t separate out good parenting skills from family income. The two are so strongly correlated. So this is an utterly misleading portrayal of the evidence.”

The report says inequalities are exacerbated by differences in the mother’s education, the father’s job and deprivation in the area where they live. Details of how far up the salary scale the effect occurs are expected in the report.

Brain areas linked to mental performance

What? It's not "poverty" that makes you dumb? Once again the data contradict Leftist nostrums. Many of the skills mentioned below are closely linked to IQ. Mental speed and brain size have long been known as correlated with IQ. So the research below confirms a lot in IQ research. Note the confirmation that IQ can't be "trained"

HOW well you play a video game can be predicted by measuring the size of structures in your brain. Researchers have found certain brain centres play a vital role in influencing traits crucial to video game success. The findings could lead to applications for education and treatment of dementia.

The study, published in the scientific journal Cerebral Cortex, adds to evidence that a collection of distinctive tissues deep in the brain influence the ability to refine motor skills, learn, plan, and adapt quickly to a changing environment. "This is the first time that we've been able to take a real-world task like a video game and show that the size of specific brain regions is predictive of performance and learning rates," said University of Pittsburgh psychology professor Kirk Erickson.

The study was done by Pittsburgh University, the Massachusetts Institute of Technology, the McGovern Institute for Brain Research, and the Beckman Institute for Advanced Science and Technology at the University of Illinois.

Researchers explored an anomaly between novice and veteran players. Research had shown expert players outperformed novices in areas such as attention and perception. But training novices for endless hours produced no measurable benefit to their cognitive abilities.

The study's authors believed existing differences between individual brains might explain the anomaly. They concentrated on an area known as the striatum. "Our animal work has shown that the striatum is a kind of learning machine - it becomes active during habit formation and skill acquisition," said McGovern Institute investigator Ann Graybiel. "So it made a lot of sense to explore whether the striatum might also be related to the ability to learn in humans."

The researchers used high-resolution magnetic resonance imaging to analyse brain regions of 39 adults aged between 18-28 who'd spent less than three hours a week playing video games in the previous two years.

Half were asked to focus on maximising their score; the rest were asked to periodically shift priorities, improving skills in one area before moving to something else. Players who had a larger brain "reward centre" did better early on; players whose brain centres for motor skills and adaptation were larger performed best overall.
