Improving Fluid Intelligence With Training On Working Memory
According to David Geary, Gf and Gc can be traced to two separate brain systems. Fluid intelligence involves the dorsolateral prefrontal cortex, the anterior cingulate cortex, and other systems related to attention and short-term memory. Crystallized intelligence appears to be a function of brain regions that involve the storage and usage of long-term memories, such as the hippocampus.
In a controversial study, Susanne M. Jaeggi and her colleagues at the University of Michigan, found that healthy young adults who practiced a demanding working memory task (dual n-back) approximately 25 minutes per day for between 8 and 19 days, had statistically significant increases in their scores on a matrix test of fluid intelligence taken before and after the training than a control group who did not do any training at all.
A second study conducted at the University of Technology in Hangzhou, China, supports Jaeggi's results independently. After student subjects were given a 10 day training regime based on the dual n-back working memory theory, the students were tested on Raven's Standard Progressive Matrices. Their scores were found to have increased significantly.
Subsequent studies, namely by Chooi & Thompson, Redick et al do not support Jaeggi claims. Although participants' performance on the training task improved, results from latter did not suggest any significant improvement in the mental abilities tested, especially fluid intelligence and working memory capacity. The meta-analytic review concluded that "memory training programs appear to produce short-term, specific training effects that do not generalize."

Famous quotes containing the words improving, fluid, intelligence, training, working and/or memory:
“She was so overcome by the splendor of his achievement that she took him into the closet and selected a choice apple and delivered it to him, along with an improving lecture upon the added value and flavor a treat took to itself when it came without sin through virtuous effort. And while she closed with a Scriptural flourish, he “hooked” a doughnut.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“On and on eternally
Shall your altered fluid run,
Bud and bloom and go to seed;
But your singing days are done;”
—Edna St. Vincent Millay (1892–1950)
“The intelligence suffers today automatically in consequence of the attack on all authority, advantage, or privilege. These things are not done away with, it is needless to say, but numerous scapegoats are made of the less politically powerful, to satisfy the egalitarian rage awakened.”
—Wyndham Lewis (1882–1957)
“I am not a suffragist, nor do I believe in “careers” for women, especially a “career” in factory and mill where most working women have their “careers.” A great responsibility rests upon woman—the training of children. This is her most beautiful task.”
—Mother Jones (1830–1930)
“Boredom and fear keep us working and obeying the laws.”
—Mason Cooley (b. 1927)
“‘Tis of the essence of life here,
Though we choose greatly, still to lack
The lasting memory at all clear,
That life has for us on the wrack
Nothing but what we somehow chose;
Thus are we wholly stripped of pride
In the pain that has but one close,
Bearing it crushed and mystified.”
—Robert Frost (1874–1963)
