The phrase crystallized intelligence
describes static or systematic knowledge that is accumulated piece-by-piece over the course of a lifetime, career, or practice within a specific subject. Methods to improve it abound; standardized tests, study groups, flash cards, rote learning, and highly specialized apprenticeships could all be understood as mechanisms to promote crystallized intelligence. But fluid intelligence
has proved difficult to develop directly, as training methods which promote the development of working memory capacity often fail to offer generalizable results. In response, 2008 study explored methods to improve fluid intelligence
(previously mentioned on mefi
) via a short-term memory game of unbounded difficulty, dual n-back
, in which players must remember increasingly long series of positions and sounds. Study participants who played the game for 19 days showed marked improvement in fluid intelligence capacity relative to controls--- the authors argue that they have explored a method to improve fluid intelligence. A subsequent study has further demonstrated that working training games can in turn improve crystallized intelligence acquisition among learning-disabled students.
