Psychology as a self-conscious field of experimental study began in 1879, when Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research in Leipzig, Germany. Wundt was also the first person to refer to himself as a psychologist.
Wundtâs 1874 book, Principles of Physiological Psychology, expanded on his experimental psychology theories, and in 1875, Wundt accepted the position of professor of philosophy at the University of Leipzig. Wundt created the first psychological research journal, Philosophical Studies, in 1881.
