Mental Fatigue in Day School Children as Measured by Immediate Memory. Part I from the Journal of Educational Psychology, 3:18-28 (1912).
The chief defect in the measurement of mental fatigue in children by tests of immediate memory has been the irregularity and variation in intellectual work in the early part of a series of new exercises. In the present investigation practice was continued until the pupils' performance became "steady," before the fatigue tests were begun. Tests with a class of forth6-five boys, averaging thirteen years of age, showed a relative inefficiency in the work of the late afternoon as compared with that of the early morning. The reduction in efficiency amounted to five or six percent.

Mental Fatigue in Day School Children as Measured by Immediate Memory. Part II from the Journal of Educational Psychology, 3:75-82 (1912).
Tests of immediate memory on a class of fifty-one boys, averaging eleven years of age, showed a slight relative inefficiency in the work of the late afternoon as compared with that of the early morning. The increase in efficiency was about two per cent.
