You are at a lecture about the history of psychology and the speaker states that Wilhelm Wundt’s theory of structuralism was the first scientific psychological theory. On what historical fact might the speaker be basing her or his argument?

A. Wundt was internationally known at the time, and this lent credence to his theory in the
scientific community.
B. Wundt studied under Ivan Pavlov for his graduate training, and Pavlov required scientific
methods to be used.
C. Structuralism was based on the results of his introspection experiments, so it is, at least in part, empirical.
D. Structuralism was based on careful anecdotes gathered from Wundt’s extensive clinical
career.
