Which of the following factors is not related to Vernon's hierarchical intelligence theory?

Question

Accepted Answer

The correct option is 2:
Vernon's Hierarchical Theory of Intelligence is structured as a pyramid, differentiating intelligence into four levels or factors. The levels move from a general ability at the top to very specific abilities at the bottom. These four hierarchical levels are: the General factor (G-factor) at the apex, two Major Group Factors immediately below G, several Minor Group Factors beneath the Major Group Factors, and finally, numerous Specific Factors (S-factors) at the base. All these factors represent different degrees of generality in mental abilities. The term "Personal factor" is not a component or level within Vernon’s recognized structure of intelligence. The theory focuses on cognitive abilities, not non-cognitive personality or "personal" traits as structural components of intelligence itself.

The incorrect option is 1 (Major factor):
Major group factors, such as verbal-educational and practical-mechanical ability, are the second level in Vernon's hierarchy, immediately beneath the General factor. They represent broad categories of cognitive abilities derived from the general factor. These factors are essential parts of the structure, making this option incorrect as the non-related factor.

The incorrect option is 3 (Minor factor):
Minor group factors are the third level of the hierarchy, sitting below the major group factors. They represent even more specific clusters of abilities within the major groups. These factors are explicitly included in Vernon's model, therefore, it cannot be the factor that is not related.

The incorrect option is 4 (Specific factor):
Specific factors form the lowest and broadest level of the hierarchy. These factors are highly specialized skills required for specific tasks or tests. Since specific factors are the base of Vernon’s hierarchical model, they are definitely related to the theory.
