Wilhelm Wundt (1832–1920) was a German scientist recognized as the first individual to be referred to as a psychologist. He viewed psychology as the scientific study of conscious experience, believing its primary goal was to identify the fundamental components of consciousness and understand how they combine to create that experience. To achieve this, Wundt utilized 'internal perception,' or introspection, a process where individuals objectively examine their own conscious thoughts, treating the human mind as an observable aspect of nature. His approach, termed experimental introspection, relied on instruments to precisely measure reaction times. He also championed voluntarism, the idea that individuals possess free will and should be aware of a psychological experiment's intent if they participate. Wundt authored 'Principles of Physiological Psychology' in 1873 and later published 'Völkerpsychologie' in 1904, advocating for the inclusion of cultural studies in psychology. Although he laid the groundwork, it was his student, Edward Titchener, who formally developed structuralism.
