What distinguished Wilhelm Wundt and contribution from other contributions to psychology?

Wilhelm Wundt is often referred to as the father of experimental psychology for establishing the first psychology research laboratory in 1879 at the University of Leipzig. His emphasis on using scientific methods to study human behavior and his focus on introspection to understand mental processes were significant contributions that distinguished his work from others in the field. Wundt's structuralism approach laid the foundation for the development of psychology as a formal field of study.
