INTRODUCTION 



The psychology of the new century is seeking to discover how 

 the mind performs its task in the work-a-day world. The pion- 

 eer study in this field was made by Bryan and Harter (7) on learn-

 a careful study of the art of typewriting, Diehl (12), Downey 

 (13), Judd and others of the hand writing process; and, similarly, 

 Miinsterberg (31) has studied the complex mental operations 

 involved in ship-navigation, in running an electric car and in
