Can fluid intelligence be improved? And under what circumstances?
Here, we present evidence for transfer from training on a demanding working memory task to measures of Gf. This transfer results even though the trained task is entirely different from the intelligence test itself. Furthermore, we demonstrate that the extent of gain in intelligence critically depends on the amount of training: the more training, the more improvement in Gf. That is, the training effect is dosage-dependent. Thus, in contrast to many previous studies, we conclude that it is possible to improve Gf without practicing the testing tasks themselves, opening a wide range of applications. (Source)
Is this result merely the effect of IQ Expectations?
Brain Training rounds up arguments against brain training claims.
Not So True Grit finds that consistency doesn’t matter to grit, although perseverance does.
Grit’s 6% argues that intelligence as a relatively stable trait predicts almost half of performance in various measures.
