How did Wilhelm wundt pioneered the investigation of mental processing?

Wilhelm Wundt pioneered the investigation of mental processing by establishing psychology as a distinct scientific discipline through his creation of the first experimental psychology laboratory in 1879 at the University of Leipzig. He employed introspection as a method to explore conscious experience, encouraging subjects to report their thoughts and feelings in response to stimuli. Wundt's focus on the systematic study of the mind laid the groundwork for experimental methods in psychology and highlighted the importance of empirical research in understanding mental processes. His work marked a shift from philosophical speculation to scientific inquiry in the study of the mind.
