Psychology, Its Facts and Principles

By Harry L Hollingworth

"Psychology, Its Facts and Principles" provides a rigorous examination of the laws governing human consciousness and behavior. Harry L. Hollingworth, a central figure in the development of applied psychology, synthesizes the empirical findings of his era to present a cohesive set of psychological principles. The work explores the intricate relationships between stimuli, mental states, and physical actions, offering a structured approach to the study of the mind.

The text covers a broad spectrum of topics, including the mechanics of perception, the nature of learning, and the complexities of human motivation. By focusing on observable facts rather than mere speculation, Hollingworth contributes to the professionalization of psychology as a distinct scientific discipline. This book remains a vital touchstone for understanding the evolution of psychological thought and the methodology of early 20th-century behavioral research. It is a compelling read for those interested in the history of science and the foundational concepts of modern mental health and behavioral studies.
