The author offers a concise introduction to experimental psychology aimed at beginners, prioritizing scientific point of view over encyclopedic facts. The text emphasizes distinguishing empirical fact from theoretical meaning, advocates careful introspection as a method while discarding the term consciousness, and declines to treat nervous physiology in detail, directing students instead to primary physiological sources. Each chapter supplies questions and references to test understanding and encourage further reading. Throughout the work the writer warns against muddled thinking, seeks clarity of concepts and terminology, and presents methodological guidance and representative topics for elementary study.
