Jack up your brain power

A person’s “fluid intelligence”— the ability to reason and to solve new problems independently of previously acquired knowledge—was long thought to be fixed, something that couldn’t be taught.

But new research from the University of Michigan suggests that memory-building exercises can also boost fluid intelligence. In everyday life, that could result in greater problem solving ability, superior performance on intellectual tasks and even more success at work.

In the study, memory-training exercises were given to four groups, who repeated the exercises for eight, 12, 17, or 19 days. The trained subjects showed significant improvement compared to control subjects. "The more training, the more improvement in fluid intelligence," says psychology researcher Susanne Jaeggi.
