How working memory enables fluid reasoning
Abstract
The strong relation between fluid reasoning (Gf) and working memory (WM) is well established. Gf depends on WM to hold necessary information in a span of awareness until the reasoning task is completed. The influence of time constraints on the Gf-WM relation indicates that the abilities to control attention and inhibit interference may be the underlying traits that account for the Gf-WM relation. Neuroanatomy also explains the interrelations among these cognitive processes. Neuroimaging (fMRI) studies have confirmed that the same regions of the prefrontal cortex (PFC) are active during Gf and WM functioning. The dorsolateral prefrontal cortex (dPFC) is also a critical structure for attention functions and inhibition.
Keywords: Attention; fluid reasoning; inhibition; prefrontal cortex; working memory.
