Ebbinghaus, founder of the experimental study of memory, said that psychology has a long past but a short history. The former refers to models of psychology held from antiquity to modern times preceding psychology as a science. The latter refers to the century of psychology as a modern empirical science.

Demonstrations will be based on the original texts and methods with special emphasis given the ways that psychological method and theory evolved to their present form.
