Psychology

<OpenstaxParagraph>
	Wilhelm <OpenstaxTerm>Wundt</OpenstaxTerm> (1832–1920) was a German scientist who was the first person to be referred to as a psychologist. His famous book entitled <OpenstaxEm>Principles of Physiological Psychology</OpenstaxEm> was published in 1873. Wundt viewed psychology as a scientific study of conscious experience, and he believed that the goal of psychology was to identify components of consciousness and how those components combined to result in our conscious experience. Wundt used <OpenstaxTerm>introspection</OpenstaxTerm> (he called it “internal perception”), a process by which someone examines their own conscious experience as objectively as possible, making the human mind like any other aspect of nature that a scientist observed. He believed in the notion of voluntarism—that people have free will and should know the intentions of a psychological experiment if they were participating (Danziger, 1980). Wundt considered his version experimental introspection; he used instruments such as those that measured reaction time. He also wrote <OpenstaxEm>Volkerpsychologie</OpenstaxEm> in 1904 in which he suggested that psychology should include the study of culture, as it involves the study of people. Edward Titchener, one of his students, went on to develop <OpenstaxTerm>structuralism</OpenstaxTerm>. Its focus was on the contents of mental processes rather than their function (Pickren &amp; Rutherford, 2010). Wundt established his psychology laboratory at the University at Leipzig in 1879 (<a href="#CNX_Psych_01_02_Wundt">Figure 1.2</a>). In this laboratory, Wundt and his students conducted experiments on, for example, reaction times. A subject, sometimes in a room isolated from the scientist, would receive a stimulus such as a light, image, or sound. The subject’s reaction to the stimulus would be to push a button, and an apparatus would record the time to reaction. Wundt could measure reaction time to one-thousandth of a second (Nicolas &amp; Ferrand, 1999).

<OpenstaxParagraph>
	However, despite his efforts to train individuals in the process of introspection, this process remained highly subjective, and there was very little agreement between individuals.
