The Trained Memory / Being the Fourth of a Series of Twelve Volumes on the / Applications of Psychology to the Problems of Personal and / Business Efficiency

The text examines human memory as a set of perceptual and recall processes, distinguishing conscious, semi-automatic, and subconscious mechanisms and identifying four special memory processes. It analyzes causes of forgetfulness, the roles of attention and interest, and how associations, contiguity, intensity, and habit govern retention and recall. The author critiques rote practice and popular memory systems, arguing that manufactured interest and cramming fail because they do not form rich associative complexes. Practical guidance includes exercises to sharpen observation and thought-memory, methods for remembering names, and a step-by-step system for forming correct memory habits aimed at personal and business efficiency. Applications to advertising and learning are discussed throughout.
