Under Charles Spearman's Two-Factor Theory of Intelligence, a central concept is 'General Intelligence' or the 'g-factor', defined as a universal and innate mental energy responsible for all types of intellectual tasks, logical thinking, and abstract problem-solving. Regarding its psychological implications and scientific management of cognitive development, intellectual differences, and academic performance in classroom teaching, which of the following psychological statements is most authentic and scientifically valid?

Charles Spearman proposed the Two-Factor Theory of Intelligence in 1904, stating that intellectual activities involve two types of factors: the General Factor (g-factor) and the Specific Factor (s-factor).

Key Characteristics of g-factor:

• Innate and Universal: It is considered an inborn, universal mental energy.
• Foundation for Mental Operations: It serves as a common base for executing all types of intellectual tasks and logical processes.
• Academic Impact: While specific skills (s-factor) can be trained, a student's foundational logical capacity and overall academic performance across various subjects are heavily influenced by this universal g-factor.
