The present data is based on data from the Army Alpha intelligence examination, administered to 581 males and 607 females in a representative group, between the ages of ten and sixty. Prior work has shown that for the total sample, the developmental curve is linear to about 16 years, with a negative acceleration beyond 16 to a peak between the agse of 18 and 21. A decline follows, which is much more gradual than the rise during adolescence, but which by the age of 55 involves a recession to the 14-yr level.
