ABSTRACT

DETAILED reviews of research with the M.P.I, have been given by Jensen (1958, 1965), Knapp (1960), and others; here we will confine ourselves to certain general statements of the type of results which have been reported in the literature. 1 First of all we will note the results of work done in the English speaking countries, that is to say England, the United States, Canada and Australia; then we will go on to see to what extent these findings are duplicated in other countries like Italy, Japan, India and so on.
