Which of the following represents the most subtle and critical theoretical difference between Howard Gardner's 'Theory of Multiple Intelligences' and Charles Spearman's 'Two-Factor Theory'?

Understanding Theories of Intelligence

Howard Gardner, in his 'Theory of Multiple Intelligences', postulated that intelligence is not a single general unit, but rather consists of several independent types of intelligences (such as linguistic, logical-mathematical, musical, spatial, etc.).

In contrast, Charles Spearman proposed the 'Two-Factor Theory', which includes the General factor (G-factor) and Specific factor (S-factor). Here, the G-factor acts as a universal energy or capacity behind all types of intellectual tasks.

• Gardner's View: Autonomous and distinct multiple intelligences.
• Spearman's View: Unified general intelligence (G-factor) underlying performance.
