Who is credited with establishing the first research lab in psychology in the United States?

Stanley Hall is recognized for establishing the first research laboratory dedicated to psychology in the United States at Johns Hopkins University in 1883. His work laid the foundation for psychological research and experimentation in the country, promoting the scientific approach to understanding human behavior and mental processes. Hall was instrumental in the development of psychology as a formal discipline, contributing significantly to educational psychology and child development.

In contrast, while Freud is known for his psychodynamic theories, he did not establish a laboratory in the U.S. Likewise, John Watson, who is known for developing behaviorism, contributed to psychological theory later and was influenced by the foundational work of Hall but did not establish the first lab himself. William James, a prominent psychologist and philosopher, made significant contributions to psychology, but he is not credited with setting up the first research laboratory in the U.S.; his work focused more on functionalism rather than the establishment of a laboratory.
