Correct Answer: Correct answer is: (D) Spearman's two factor theory.
Exam Relevance: GRE, GMAT, Psychology exams
Difficulty: Moderate
Concept notes: Spearman's two-factor theory of intelligence posits the existence of a general intelligence factor 'g' and specific intelligence factors 's'.
Common Mistakes: Students may confuse Spearman's theory with other hierarchical models of intelligence, such as Vernon's hierarchical theory or Guilford's structure of intellect.
Explanations: Spearman's two-factor theory suggests that intelligence can be divided into a general factor 'g', which underlies all cognitive abilities, and specific factors 's', which are unique to particular cognitive tasks. This theory is distinct from other models like Guilford's theory of intellect, which focuses on a wide range of cognitive abilities, and Vernon's hierarchical theory, which proposes a more complex structure of intelligence.
Option Analysis: - Option A: Anarchic theory is not a recognized theory of intelligence.
- Option B: Vernon's hierarchical theory proposes a more complex structure of intelligence, not just 'g' and 's' factors.
- Option C: Guilford's theory of intellect focuses on a wide range of cognitive abilities, not just 'g' and 's' factors.
- Option D: Spearman's two-factor theory correctly advocates the presence of general intelligence 'g' and specific intelligence 's' factors.
Mnemonic: G for General, S for Specific
