Sternberg's triarchic theory of intelligence

Sternberg 's theory of intelligence is made up of three different components: creative, analytical, and practical abilities. Creativeness is the ability to have new original ideas, and being analytical can help a person decide whether the idea is a good one or not. "Practical abilities are used to implement the ideas and persuade others of their value". In the middle of Sternberg's theory is cognition and with that is information processing. In Sternberg's theory, he says that information processing is made up of three different parts, meta components, performance components, and knowledge-acquisition components. These processes move from higher-order executive functions to lower-order functions. Meta components are used for planning and evaluating problems, while performance components follow the orders of the meta components, and the knowledge-acquisition component learns how to solve the problems. This theory in action can be explained by working on an art project. First is a decision about what to draw, then a plan and a sketch. During this process there is simultaneous monitoring of the process, and whether it is producing the desired accomplishment. All these steps fall under the meta component processing, and the performance component is the art. The knowledge-acquisition portion is the learning or improving drawing skills.
