Explanation

The Two-Factor Theory of intelligence was developed by Charles Spearman.
This theory posits that intelligence is composed of a single 'general intelligence' factor (g-factor) and multiple 'specific' factors (s-factors).
The g-factor is a broad mental capacity that influences performance on all cognitive tasks.
The s-factors are specific abilities required for particular tasks, such as verbal, mathematical, or spatial skills.

Option B: Louis L. Thurstone proposed the Group Factor Theory (or Multifactor Theory), not the Two-Factor Theory.
Option C: Garset is not a recognized psychologist associated with a major theory of intelligence. This option serves as a distractor.
Option D: This likely refers to Edward Thorndike, who also proposed a multifactor theory of intelligence, but it is distinct from Spearman's Two-Factor theory. Thorndike's theory focused on abstract, concrete, and social intelligence.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Theories of Intelligence as background academic context rather than a clinical decision trigger.
Understanding theories of intelligence helps nurses appreciate the diverse cognitive strengths and weaknesses of patients.
This knowledge is crucial for tailoring patient education and communication strategies. A patient might have difficulty with abstract reasoning (g-factor) but excel at learning a specific motor skill (s-factor) for self-care.
What if a patient has a high g-factor but a low s-factor for memory? The nurse would need to provide written instructions and use memory aids, rather than relying solely on verbal explanation, to ensure adherence to treatment.
