He pointed out that the latter involves knowledge acquisition and crystalized skills which can be upset individually without impacting the others.

These are fluid intelligence and crystallized intelligence. General intelligence encapsulates correlations among various cognitive tasks which can be categorized into two subdivisions (Cattell, 1971). It is a construct of psychometric investigations of human intelligence and our cognitive abilities. Our capacity to learn the novel and recall the past is called general intelligence (Cattell, 1963). ![]()
