Ways to Inflate Your IQ
Your Intelligence Level Can Fluctuate, Studies Show; Battling the Post-Vacation Dip

Many people think of IQ as a genetic trait, like brown eyes or short legs: You're born with it and you're stuck with it. Now, a growing body of research is showing that a person's IQ can rise—and even fall—over the years.
Scores can change gradually or quickly, after as little as a few weeks of cognitive training, research shows. The increases are usually so incremental that they're not immediately perceptible to individuals, and the intelligence-boosting effects of cognitive training can fade after a few months.
In the latest study, 33 British students were given IQ tests and brain scans at ages 12 to 16 and again about four years later by researchers at the Wellcome Trust Centre for Neuroimaging at University College London; 9% of the students showed a significant change of 15 points or more in IQ scores.
On a scale where 90 to 110 is considered average, one student's IQ rose 21 points to 128 from 107, lifting the student from the 68th percentile to the 97th compared with others the same age, says Cathy Price, professor of cognitive neuroscience at the center and co-author of the study, published last month in Nature. Another student's score skidded out of the "high average" category, to 96 from 114.
