It has often been claimed that Wilhelm Wundt, the father of modern psychology, was the first to adopt introspection to experimental psychology[REF] though the methodological idea had been presented long before, as by 18th century German philosopher-psychologists such as Alexander Gottlieb Baumgarten or Johann Nicolaus Tetens [REF].
Edward Titchener was an early pioneer in experimental psychology and student of Wilhelm Wundt [REF].
