"The present work has been written to take the place of the author's "Outline of Psychology." The Outline, which was stereotyped in 1896, had long passed beyond the possibility of revision, and the continued demand for it showed that there was still room in the science for a text-book which set experimental methods and experimental results in the forefront of discussion. The Text-book follows, in general, the lines laid down in the Outline. Broad topics discussed in this book include: sensation, affection, attention, perception, association, memory and imagination, action, emotion, and thought."

The general purpose with which this book has been written is sufficiently indicated by its title. I have selected a number of the 'classical' experiments of Experimental Psychology, and have tried to present them in such a way that their performance shall have a real disciplinary value for the undergraduate student. Within this general purpose, my aim has been two-fold. I have sought to show, in the first place, that psychology is above the laboratory: that we employ our instruments of precision not for their own sake, but solely because they help us to a refined and more accurate introspection. And secondly, just as in my Outline of Psychology and Primer of Psychology I gave the results of experimentation a prominent place in the psychological system, so here I have treated the selected experiments not as separate exercises, but as points of departure for systematic discussion.
