Definition of Triarchic Theory of Human Intelligence
was formulated by Robert J. Sternberg, a prominent figure in the research of human intelligence. The theory by itself was groundbreaking in that it was among the first to go against the psychometric approach to intelligence and take a more cognitive approach. 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” (Sternberg, 1985, p. 45), which means that intelligence is how well an individual deals with environmental changes throughout his lifespan. Sternberg’s theory comprises three parts: componential, experiential, and practical.
