Die Physiologie und Psychologie des Lachens und des Komischen.
 Ein Beitrag zur experimentellen Psychologie für Naturforscher, Philosophen und gebildete Laien.

by Ewald Hecker

"Die Physiologie und Psychologie des Lachens und des Komischen" by Ewald Hecker is a scientific publication written in the late 19th century. This work explores the physiological and psychological aspects of laughter and humor, aiming to provide an experimental basis for understanding these phenomena. Hecker, who served as a second physician at an institution for mentally ill patients, seeks to bridge physiology and psychology through the lens of humor and laughter. The opening of the book begins with an editor's note addressing the formatting and minor spelling corrections made to the original text. Hecker dedicates his work to his mentor, Dr. Karl Kahlbaum, expressing his gratitude for the support he received during his studies. He clarifies that this book is the culmination of his research into the relationship between physiological responses (like laughter) and their psychological triggers, particularly the comic impulse. He sets out to explore the purpose of laughter and its connections to both physical sensations such as tickling and emotional states, proposing a structured investigation into these topics.
