Group means of the 16 tests performed in this experiment are shown in Fig. 4. Learning capacity appears severely disturbed half an hour after shock. Four hours after treatment the greater part of the recovery has already occurred, but some further improvement is seen during the next 24 hr.

Immediate postshock impairment and recovery after single shocks (experiment I, N = 40). Tests 4, 7, 10, 13 = 30 min after shock. Tests 5, 8, 11, 14 = 4 hr after shock. Tests 6, 9, 12, 15 = 28 hr after shock
