Sternberg's componential theory of intelligence is part of his triarchic theory of intelligence, which divides intelligence into three types: analytical, creative, and practical. The components of componential intelligence include:
1. Performance Components: These are the processes involved in performing a task, such as the mental steps or strategies we use to complete a problem.
2. Knowledge Acquisition Components: These are the processes used to gain knowledge, including how we encode and store information.
3. Metacomponents: These are higher-level cognitive processes involved in decision-making, planning, and monitoring performance.
However, Behavioural Components are not part of componential intelligence according to Sternberg’s model. Therefore, the correct answer is "Behavioural Components."
