"Association Tests Used in Psycho-Analysis " Daniel H. Bonus, 1925 (No. 784 - Little Blue Book)
 
Daniel H. Bonus authored Association Tests Used in Psycho-Analysis (No. 784) for the Haldeman-Julius "Little Blue Book" series, a project dedicated to making elite knowledge accessible to the masses for just a few cents. Bonus was a prolific contributor to the series, specializing in translating the era’s "New Psychology" into practical DIY manuals with titles like How to Psycho-Analyze Yourself and Psycho-Analysis and the Link Between Mind and Body. In this specific volume, he strips away the academic dense-work of Carl Jung to provide a lean, clinical toolkit designed to help the average reader unearth suppressed emotional "complexes" through timed word-response drills. Rather than a dry history, Bonus presents the work as an active investigative guide, teaching the reader to act as a "mental detective" by observing physical tells and reaction delays that signal a breach in the subject’s conscious defense.
