What is Structuralism?
Discovered by Wilhelm Wundt and expanded on by his colleague Edward Titchener
Wundt and Introspect
When instructing Titchener, Wundt made a clear distinction between pure introspect (unstructured self-observation) and experimental introspect. This type of introspect uses laboratory instruments to vary conditions and make results of internal perceptions more precise, according to Wundt.
When Titchener took his research and Wundt's work with him to America, his translation of Wundt's work caused a lot of it's original meaning to be lost.
