![]() 108) reflects the theory that fluid intelligence tends to decline significantly between ages 25 and 75. A table presented by Moseley and Dessinger (2006, p. It is generally believed that fluid intelligence peaks and then declines earlier in life while crystallized intelligence continues to develop throughout our lifetimes as we accumulate and store more and more experiences. The theory was later integrated with John Carroll’s three-stratum theory to become the Cattell-Horn-Carroll (CHC) theory of intelligence which McGrew (2004) praised as “the tent that houses the two most prominent psychometric theoretical models of human cognitive abilities.” He collaborated with his colleague and former student, John Horn, to develop the Cattell-Horn theory of fluid and crystallized intelligence which “suggests that intelligence is composed of a number of different abilities that interact and work together to produce overall individual intelligence” (Van Wagner, 2009). Psychologist Raymond Cattell “observed that not all intellectual abilities stopped developing at maturity, but rather two separate processes could be discerned” (Garlick, 2002, p. 31) define fluid intelligence as that “associated with the ability to learn new things, to draw influences, and to solve novel problems” as differentiated from crystallized intelligence which they suggest “refers to memory and information that has been acquired in the form of vocabulary and declarative and procedural knowledge.” While we all rely upon fluid and crystallized intelligence to at least some degree in our day-to-day living, the workplace presents a particularly compelling utilization of both upon which to focus if for no other reason than that is where many of us spend such a significant amount of our time and our effort over a relatively long period of our lives. ![]() One such dimension of exploration is the difference between fluid and crystallized intelligence. Human intelligence is defined, measured, and explored in many ways. 2.1 - Fluid and Crystallized and Fluid Intelligence in the Workplaceīy Mark Norland (a research paper written for a UC Berkeley psychology class - Fall, 2009 - Grade: A+) ![]()
