First published in 1917 and this edition in 1920, Lectures on Industrial Psychology by Bernard Muscio explores the application of psychological principles to industry, aiming to enhance efficiency and worker well-being. The book examines key topics such as mental factors affecting industrial performance, worker selection based on natural aptitude, optimal work methods, and the broader benefits of integrating psychology into industrial practices. Organized into five insightful chapters and a preface, this pioneering work remains a foundational text for understanding the intersection of psychology and industry.
