This book corresponds to a German book, which I published a few months ago, under the title _Psychologie und Wirlschaftsleben: Ein Beitrag zur angewandten Experimental-Psychologie_ (Leipzig: J.A. Barth). It is not a translation, as some parts of the German volume have been abbreviated or entirely omitted and other parts have been enlarged and supplemented. Yet the essential substance of the two books is identical.
PREFATORY NOTE
From Psychology and Industrial Efficiency by Hugo Münsterberg.
