Question 6

A student consistently achieves high grades across all academic subjects, including mathematics, science, and literature. However, they struggle significantly with tasks requiring fine motor skills and artistic expression, such as intricate drawing or sculpting. According to Spearman's Two-Factor Theory of Intelligence, which of the following best explains this student's profile?

Accepted Answer

A. The student possesses a high 'g' factor but a lower 's' factor for artistic and motor skills. — Spearman's theory posits a general intelligence ('g' factor) underlying all cognitive tasks and specific intelligences ('s' factors) for particular abilities. The student's consistent high performance across diverse academic areas indicates a strong 'g' factor. Their struggle with specific artistic and motor tasks points to a relatively lower 's' factor for those particular domains, making option A the correct choice. Options B, C, and D misrepresent the nature of 'g' and 's' factors.

Answer

B. The student has a low 'g' factor, compensated by high 's' factors for academic subjects.

Answer

C. The student's 's' factor for general intelligence is high, while their 's' factor for specific academic skills is low.

Answer

D. The student demonstrates a strong 's' factor for logical reasoning but a weak 'g' factor for overall performance.
