"One of the most robust, and we believe, important findings is that WMC strongly predicts fluid intelligence (Gf), the ability to solve new problems and learn new information ... . A central feature of many models of the working memory system is a domain-general executive attention, sometimes called a central executive, which regulates other components of the system[.] We argue that this attentional component forms the basis of the WMC-Gf relationship."
