Wilhelm Wundt (1832 August16-1920 August 31), a German psychologist and philosopher, was the founder of the first psychology laboratory and a representative figure of constructivist psychology. His Principles of Physiological Psychology is the first and most important work in the history of modern psychology. 1836, Feng Te received a doctor's degree in medicine. 1875, he became a professor of philosophy at the university of Leipzig, where he established the world's first psychology laboratory. William Feng Teyu 1832, 16 was born in Neckalou, a northern suburb of Mannheim. He studied at the University of Dubingen and the University of Heidelberg, majoring in medicine, and later studied physiology. /kloc-in 0/855, he received his doctor's degree in medicine from the University of Heidelberg, Germany, and his doctoral thesis was entitled "Neurological changes of degenerated organs caused by inflammation". From 1855- 1874, Feng Te has been engaged in teaching and research at the University of Heidelberg. In 1858, he was hired as Helmholtz's assistant. At that time, it was stipulated that all those who wanted to take Baden's national medical examination should be trained in the physiological laboratory for one semester, so Feng Te helped to train these students to do standardized experiments on muscle spasms and nerve impulse transmission. While engaged in physiological research, Feng Te's idea that psychology is an independent experimental science began to take shape. His earliest suggestions for new psychology can be found in the book Contribution to Sensory Perception Theory. In this book, Feng Te not only reported his initial experiments, but also expressed his views on new psychological methods, and talked about "experimental psychology" for the first time. 1873- 1874, Feng published his important psychological work, Physiological Psychology, which was regarded as a record of the progress of new psychology. From 65438 to 0875, Feng Te was hired as a professor of philosophy by Leipzig University, and began his long but also the most important academic period. He worked there for 45 years. 1879, Feng Te established the world's first psychology laboratory in Leipzig university. The appearance of this laboratory can be said to be a milestone in the history of psychology, marking the birth of a new psychological science. 1920, Feng Te wrote his autobiography "Experience and Cognition", recalling his hard life in the field of psychology. Shortly after the publication of this book, he died in Leipzig on August 3 1, 1920 at the age of 88. Wilhelm Wundt introduced introspection experiment into psychology. He asked the other person to reflect on himself, and then described his views on his psychological working methods. He created a special way to train each other and make them look at themselves more carefully and perfectly, but he didn't explain his psychology too much. This way of working is very different from psychology at that time. Psychology at that time was more of a branch of philosophy. Wilhelm Wundt thinks that psychology and physiology are interrelated. His epistemology combines the theories of Spinoza, Leibniz, Kant and Hegel. Feng Te claimed that his psychology was content psychology, and some of his viewpoints were inherited by Tichina and developed into structural psychology. His main contribution is to transform psychology into an independent subject based on experiments. /kloc-psychologists in the mid-9th century began to conduct some psychological experiments before Feng Te, but most of the research at that time was combined with experimental physiology and was conducted in the physiological laboratory. Because of Feng Te's efforts in theory and research, psychology has been separated from philosophy and physiology, and moved towards a truly independent road. Feng Te's physiological psychology refers to a kind of psychology studied by physiological methods. He believes that psychology studies people's direct experience, which is different from all sciences that study indirect experience, so it is necessary to find a special experimental method that can measure direct experience. This experimental method is the introspective experimental method adopted by the first psychology laboratory he founded. Before him, because it was difficult to distinguish psychological experiments from physiological experiments, purely introspective philosophical psychology still had certain advantages. Feng Te's introspective report following the experimental procedure made the purely introspective philosophical psychology history. On the other hand, because the research object of introspection experiment is psychological activity characterized by direct experience, Feng Te strictly distinguishes experimental psychology from physiological psychology experiment. Although there are still many insurmountable defects in Feng Te's introspective experimental method, which caused many criticisms from experimenters later, most psychologists admit his historical contribution as the first experimental psychologist.
