The role of working memory and updating in Coloured Raven Matrices performance in typically developing children.

A large body of evidence indicates that working memory correlates with performance on fluid intelligence tasks such as Raven’s tests. However, light still needs to be shed on which particular aspects of working memory might be most critically related to fluid intelligence, and whether working memory updating* which appears crucial to intellectual functioning*has a prominent role. To address these issues more closely, our study presented participants (aged 511 years) with the Raven’s Coloured Progressive Matrices, an updating task, and a battery of working memory tasks. Our findings confirm that working memory indeed plays an important part in explaining fluid intelligence, in particular that updating information in working memory is critical to fluid intelligence in the context of development.
