ABSTRACT
We will consider first the important research carried out by Cyril Burt among children and adults. A general account of this was given in his broadcast, and printed in the book, How the Mind Works.1 Burt first selected fifty picture-postcards. He writes:
They included reproductions from classical masters, second-rate pictures by second-rate painters, every variety and type down to the crudest and the most flashy birthday-card that I could find at a papershop in the slums. The test consisted in arranging the fifty cards in order of preference.
