Complex-span tasks have also been shown to be closely related to many other aspects of complex cognitive performance besides language comprehension, among other things to measures of fluid intelligence.

However, whatever there is a great increase in mental ability test score, the performance on fluid intelligence may merely reflect greater development of related neuronal patterns .

In the same vein, training on the " n "-back task appears to improve performance on subsequent fluid intelligence assessments, especially when the training is at a higher " n "-value.

Preckel et al ., investigating fluid intelligence and creativity, reported small correlations of " r " = . 3 to " r " = . 4 across all levels of cognitive ability.

The 2008 study was replicated in 2010 with results indicating that practicing single n-back may be almost equal to dual n-back in increasing the score on tests measuring Gf ( fluid intelligence ).

Stratum II ( broad abilities ) : 8 broad abilities fluid intelligence, crystallized intelligence, general memory and learning, broad visual perception, broad auditory perception, broad retrieval ability, broad cognitive speediness, and processing speed.
47.
After this training, the groups were tested again and those with training ( compared against control groups who did not undergo training ) showed significant increases in performance on the fluid intelligence tests.
48.
These authors contend that a low score on tests which are intended to measure fluid intelligence may reflect more a lack of interest in the tasks rather than inability to complete the tasks successfully.
49.
Cross-sectional studies usually show that especially fluid intelligence peaks at a relatively young age ( often in the early adulthood ) while longitudinal data mostly show that intelligence is stable until the mid adulthood or later.

If my phrasing of the papers does not confirm wikipedian standards, it must be marked as so, but reference to the papers must present at the article on Fluid Intelligence so somebody better than me could improve the article.
