Applied Psychology: Driving Power of Thought / Being the Third in a Series of Twelve Volumes on the Applications of Psychology to the Problems of Personal and Business Efficiency

The text applies psychological principles to personal and business efficiency, explaining how ideas form through perception, association, and judgment and how emotional energy animates action. It outlines laws of association, processes of reasoning, and methods for deliberately training attention and attitude to foster confidence and creativity. Practical chapters propose psychological techniques for hiring and employee selection, including many tests for speed of thought, memory, attention, suggestibility, and movement accuracy, with discussion of implementation and limits. Interwoven are arguments about the value of ideas, the role of passion in enterprise, and how conscious mental habits can shape success or failure.
