How does the Working Memory Model explain performance differences when tasks have high verbal load compared to high spatial load?

• A. Verbal tasks rely on the central executive; spatial tasks rely on the episodic buffer; differences are explained by general memory strength.
• B. Verbal tasks rely on the phonological loop; spatial tasks rely on the visuo-spatial sketchpad; central executive allocation and interference patterns explain performance differences.
• C. Both rely primarily on the episodic buffer with minimal involvement of the phonological loop or VSSP.
• D. The visuo-spatial sketchpad handles both types of tasks equally, with no interference patterns.

Answer: (B)
