Experimental psychology has studied memory characteristics extensively meanwhile correlational psychology has analyzed the main properties of intelligence. The approach between both viewpoints are based on memory nuclear concept analysis --working memory and, the main intelligence psychometrical concept -- g factor. The available data suggests that individual differences concern to the g could be explained by cognitive concepts like span and speed linked to working memory. These data suggests new procedures to improve intelligence -- and therefore the social aspects associated to it -- by increasing system capacity of efficient information processing.
