As Minds Get Quicker, Teens Get Smarter

September 30, 2011 by  

SAN ANTONIO, Sept. 29 (UPI) — U.S. researchers say they have demonstrated for the first time that adolescents become smarter because their brains process information faster.

Researchers David Pillow, Anissa Snyder and Peter Kochunov — psychologists at University of Texas at San Antonio — said their findings make intuitive sense.

“Our research was based on two well-known findings,” Coyle said in a statement. “The first is that performance on intelligence tests increases during adolescence. The second is that processing speed — the brain taking in and using new stimuli or information — as measured by tests of mental speed also increases during adolescence.”

To find the relationship between these two phenomena, the psychologists analyzed the results of 12 diverse intelligence and mental speed tests administered to 6,969 adolescents ages 13-17 in the 1997 National Longitudinal Survey of Youth.

Intelligence was measured by performance on cognitive tests of diverse abilities, such as vocabulary knowledge, math facts and mechanical comprehension. Mental speed showed up in timed tests of computing and coding — matching digits and words and other arithmetic tasks.

The study, published in the journal Psychological Science, found in both of these categories, the researchers could see the older teenagers did better and worked faster than the younger ones. Running the data in numerous ways, the study discovered the measured increase of intelligence could be accounted for almost entirely by the increase in mental speed.

    If there is ANY truth to this, then we’d better find ways to accelerate the process. As long as Obummer and his criminals are in Washington, life will get worse and worse. America’s youngsters will either wind up
    seeing Obummer for who and what he is (we can only hope) or they will come to HATE everyone who voted for him.
    Their future is at stake in more ways than one – and I do NOT exaggerate one bit, folks. Their future is already gone and they’re obligated for money that doesn’t exist. For that, we can give “thanks” to utopian retards who thought NOTHING of putting ALL future American generations in PERPETUAL DEBT. If that’s not beyond warped and criminal, I don’t know what it is. I wonder if China is interested in buying a Manchurian Candidate – slightly used.
