Under Charles Spearman's Two-Factor Theory of Intelligence, the concept of the 'General Factor' ('g' factor)—which posits that this universal and innate mental energy is equally inherent in all types of intellectual activities, logical processing, and cognitive tasks—has specific psychological implications for classroom teaching. Regarding the scientific operation of students' general intellectual capacity, abstract reasoning, and overall performance across diverse subjects, which of the following psychological statements is most authentic and scientifically valid?

Charles Spearman proposed the Two-Factor Theory of Intelligence in 1904, according to which intelligence consists of two factors: the General Factor ('g' factor) and the Specific Factor ('s' factor).

Key Concepts of Spearman's Theory:

• General Factor ('g' factor): Considered a universal and innate mental energy that is present equally in all types of intellectual and logical activities. It represents an individual's general mental ability and influences performance across various academic domains.
• Specific Factor ('s' factor): Related to specific activities or skills which vary from person to person.

Therefore, option (b) most accurately and scientifically defines the psychological implications of this concept.
