DESPITE all that has been done in the field of educational psychology adult education has still only an empirical basis. There has been practically no research in Great Britain and very little in the United States.

The first stage is to determine the problems to which the attention of psychological investigators should be directed. The educational activities now so widespread among men and women of H. M. Forces should yield valuable data and suggestions.
