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

This guide opens a clear window onto how memory really works, breaking the subject into four basic parts—retention, recall, imagination and recognition. By demystifying the “mental treasure vault,” it shows why we often forget what seemed unimportant, and how unnoticed impressions still linger beneath the surface of awareness.

The author then moves from theory to practice, outlining the mechanisms that trigger recall, the laws that govern habit and intensity, and the common pitfalls of traditional memorization drills. Practical exercises illustrate how to strengthen observation, link ideas, and remember names, all framed for everyday business and personal tasks. Listeners will come away with a scientific system they can apply immediately, turning memory from a vague talent into a reliable tool for efficiency and creativity.
