Which sub-component is not included in componential intelligence under the…

Sternberg's Triarchic Theory of Intelligence organises intelligent behaviour into three subtheories: componential, experiential, and contextual. The componential subtheory covers the internal mental mechanisms of intelligence and is itself made up of three sub-components: metacomponents (executive planning, monitoring, and evaluation processes), performance components (the steps used to carry out a task), and knowledge-acquisition components (the processes used to learn new information).

The question asks which sub-component is NOT part of componential intelligence. Checking each option against Sternberg's three componential sub-components:

• Meta component: one of the three componential sub-components (executive planning, monitoring and evaluation).

• Experiential component: this names Sternberg's experiential subtheory (how intelligence handles novelty and the automatization of skills), which is an entirely separate subtheory from componential intelligence, not one of its three sub-components.

• Performance component: one of the three componential sub-components (executing the chosen strategy step by step).

• Knowledge acquisition component: one of the three componential sub-components (learning and encoding new information).

Since meta, performance, and knowledge-acquisition components account for all three componential sub-components, the experiential component is the one left over, confirming it as the sub-component not included in componential intelligence.
