Table 2. Number of days accrued in each training stage.

When we trained the two additional monkeys (Uranus and Neptune), we made them skip the 4th and 5th stages entirely. The performance patterns of these two monkeys were not different from those of the initial four.

Monkeys	Stage 1	Stage 2	Stage 3	Stage 4	Stage 5
Jupiter	12	39	16	65	51
Mars	29	7	15	48	42
Saturn	25	42	31	64	95
Mercury	13	38	17	61	49
Uranus	14	17	11	-	-
Neptune	13	21	11	-	-
