Who propounded the Group Factor theory of intelligence?
Detailed Explanation
📌 Core Theoretical Concept:
The Group Factor Theory of Intelligence was propounded by the eminent psychologist L.L. Thurstone. Challenging Spearman's Two-Factor theory, Thurstone argued that intelligence is not composed of a single general factor or two factors, but rather consists of a group of independent Primary Mental Abilities (PMAs). Utilizing the statistical technique of factor analysis, Thurstone initially identified seven primary abilities—such as verbal comprehension, numerical ability, spatial visualization, word fluency, memory, inductive reasoning, and perceptual speed. This theory bridges the gap between single-factor and multi-factor approaches by highlighting cluster-based cognitive competencies.
📊 Key Exam Points:
- Thurstone: Creator of the Group Factor Theory, introducing Primary Mental Abilities (PMAs).
- Spearman: Proposed the Two-Factor Theory ('G' and 'S' factors), making option B incorrect for this specific question.
- Alfred Binet: Known for developing the first intelligence test and associated with early unitarian/one-factor conceptualizations.
- Pomponazzi: A historical philosopher not linked to major structural theories of intelligence in modern educational psychology.

Deep pedagogical analysis:
Teacher eligibility tests like CTET, UPTET, and state TETs frequently test candidate knowledge regarding psychometric theories of intelligence. Thurstone's model is vital because it emphasizes multi-dimensional cognitive capabilities rather than a monolithic general intelligence score. From a pedagogical standpoint, educators must acknowledge that students possess varying profiles of primary mental abilities. Catering instruction to diverse cognitive strengths—such as combining spatial representations with verbal instructions—enhances differentiated instruction and fosters inclusive learning environments.
