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.
This is the same year that William James would set up a similar lab at Harvard. We can celebrate that year as the founding of experimental psychology! In 1879, Wundt assisted his first graduate student at true psychological research -- another milestone. In 1881, he started the journal Philosophische Studien. In 1883, he began the first course to be titled experimental psychology.
