How long has psychology been around for?
History of psychology
1879
Psychology was a branch of the domain of philosophy until the 1870s, when it developed as an independent scientific discipline in Germany and the United States. Psychology as a self-conscious field of experimental study began in 1879, in Leipzig Germany, when Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research in Germany. Wundt was also the first person to refer to himself as a psychologist. Other important early contributors to the field include Hermann Ebbinghaus (a pioneer in the study of memory), William James (the American father of pragmatism), and Ivan Pavlov (who developed the procedures associated with classical conditioning).
