Which scientist conducted the first psychological experiment?

Wilhelm Wundt is recognized as the father of modern psychology and conducted the first psychological experiment in 1879 at the University of Leipzig in Germany. His work focused on measuring the time it took for individuals to respond to stimuli, which he approached using a method he termed "introspection." This involved trained subjects reporting their conscious experiences in response to stimuli, marking a significant departure from philosophy and laying the groundwork for psychology as an experimental and scientific discipline. By establishing a dedicated laboratory for psychological research, Wundt emphasized the importance of empirical investigation and the scientific method, which are core principles in modern psychology. This pioneering experiment is often considered the official start of psychology as a distinct field of study separate from philosophy and physiology.
