Working Memory and Fluid Intelligence. A Review of its Relations

The aim of this paper is to contribute to the understanding of the relationship between working memory and fluid intelligence. A search was conducted in PubMed and Google Scholar database using a combination of the Spanish and English terms working memory (memoria de trabajo) and fluid intelligence (inteligencia fluida). The review indicates that attention control and the ability to retrieve information from long-term memory would be the processes through which working memory and fluid intelligence are related. However, there are conflicting results regarding the role of retention of information and information processing capacity in this relationship. We concluded by pointing out some methodological aspects that would enhance the understanding of the relationship between working memory and fluid intelligence
