Triarchic theory of intelligence

The triarchic theory of intelligence was formulated by Robert J. Sternberg, a prominent figure in research of human intelligence. The theory by itself was among the first to go against the psychometric approach to intelligence and take a more cognitive approach. The three meta components are also called triarchic components. The triarchic theory of intelligence was formulated by Robert J. Sternberg, a prominent figure in research of human intelligence. The theory by itself was among the first to go against the psychometric approach to intelligence and take a more cognitive approach. The three meta components are also called triarchic components. Sternberg's definition of human intelligence is '(a) mental activity directed toward purposive adaptation to, selection and shaping of, real-world environments relevant to one's life'. Thus, Sternberg viewed intelligence as how well an individual deals with environmental changes throughout their lifespan. Sternberg's theory comprises three parts: componential, experiential, and practical. Sternberg associated the workings of the mind with a series of components. These components he labeled the metacomponents, performance components, and knowledge-acquisition components. The metacomponents are executive processes used in problem solving and decision making that involve the majority of managing our mind. They tell the mind how to act. Metacomponents are also sometimes referred to as a homunculus. A homunculus is a fictitious or metaphorical 'person' inside our head that controls our actions, and which is often seen to invite an infinite regress of homunculi controlling each other. Sternberg's next set of components, performance components, are the processes that actually carry out the actions the metacomponents dictate. These are the basic processes that allow us to do tasks, such as perceiving problems in our long-term memory, perceiving relations between objects, and applying relations to another set of terms. The last set of components, knowledge-acquisition components, are used in obtaining new information. These components complete tasks that involve selectively choosing relevant information from a mix of information, some of it relevant and some of it irrelevant. These components can also be used to selectively combine the various pieces of information they have gathered. Gifted individuals are proficient in using these components because they are able to learn new information at a greater rate. Whereas Sternberg explains that the basic information processing components underlying the three parts of his triarchic theory are the same, different contexts and different tasks require different kinds of intelligence. Sternberg associated the componential subtheory with analytical giftedness. This is one of three types of giftedness that Sternberg recognizes. Analytical giftedness is influential in being able to take apart problems and being able to see solutions not often seen. Unfortunately, individuals with only this type are not as adept at creating unique ideas of their own. This form of giftedness is the type that is tested most often.
