The semi-longitudinal method was used to trace changes in the mental ages of 906 institutionalized mentally retarded subjects as a function of chronological age, and equations were fitted to the resulting growth curves. Sex differences proved to be relatively slight. The higher levels of retardation had a higher initial growth rate and a more pronounced decline at higher age levels than did the lower levels, but they did not have a longer growing season. In all but the last respect, the findings resembled those obtained by Fisher and Zeaman (1970)
