What did Francis Galton contribute to the study of intelligence?

• A. Theory of intelligence
• B. Emotional intelligence theory
• C. Theory of multiple intelligences
• D. Genetic intelligence theory

Answer: (A)

Francis Galton made significant contributions to the study of intelligence, particularly with the introduction of the idea that intelligence is heritable and can be measured. He was one of the first to apply statistical methods to the study of human abilities, and he is often referred to as a pioneer in exploring the nature of human intelligence through empirical research.

Galton's work laid the foundation for psychometrics, the field concerned with the theory and technique of psychological measurement. He proposed that intelligence could be assessed through various tests that measured sensory acuity and reaction times, arguing that these physical measures could serve as proxies for intellectual capacity.

The emphasis Galton placed on measurement and the hereditary aspects of intelligence influenced later theorists and researchers, helping to shape the modern understanding of intelligence testing. This focus on quantifiable traits is recognized as a cornerstone of the study of intelligence, differentiating Galton's contributions from other theories that followed, such as emotional intelligence or multiple intelligences.
