In psychometrics, who is known for his contributions to sense modalities?

The correct choice highlights the significant contributions of Galton in the field of psychometrics, particularly regarding sense modalities. Sir Francis Galton was a pioneer in the study of individual differences and the measurement of sensory perception. He developed methodologies to examine sensory modalities such as vision, hearing, and touch, evaluating how these senses influence human functioning and abilities.

Galton's work laid the foundation for later psychometric evaluations, contributing to the understanding of how these senses can impact intelligence and personality testing. His innovative use of statistical tools to analyze sensory data marked a pivotal moment in psychometry, advancing the field into the realm of quantitative research.

The other individuals listed, while influential in psychology, primarily focused on different areas. Skinner is well known for his work in behaviorism and operant conditioning, Pavlov for classical conditioning and his experiments with dogs, while Thorndike is recognized for his theories on learning through the Law of Effect. Each contributed to psychological science in meaningful ways, but their focuses did not extensively cover the study of sense modalities as Galton's did.
