Comparison of several styles of typography in English.

"Five styles of typography—spaced units, vertical, square span, and arrangement of one phrase per line, and conventional—were compared using untrained subjects. This paper reports two fairly independent series of experiments: a series using a tachistoscope presentation, and a series in which the subjects read passages of about 1500 words… . The tachistoscope series suggests that there are advantages to the new arrangements, but the reading series suggests that subjects must be trained to read these new arrangements before the advantage will be fully realized."
