Practical psychology : an advanced manual in the science of mental development, in eleven lessons
Practical Psychology is a 1922 self-improvement manual in eleven lessons by Frank C. Haddock, published in Meriden, Connecticut, for general readers wanting to develop the mind. Its four diagrams are schematic line drawings: an oval of overlapping mental faculties labeled sensation, perception, memory, emotion, will, thought and imagination, a pentagram linking those faculties by attention, a labeled nerve cell, and a simple rectangle with lettered points. A designer could draw on their clean black linework, enclosed shapes, and radiating star geometry for diagrammatic graphics.
