Top: Set-size functions for baseline and transfer performances for pigeons, rhesus monkeys, and capuchin monkeys as their training sets were progressively expanded from 8 items to 128 items (monkeys) or to 1024 items (pigeons). Error bars are standard errors of the mean. Bottom: Transfer by pigeons trained initially with either 8, 32, or 64 items. The resulting set-size function (black diamonds) compared to the set-size functions for groups in the top panel shows a lack of carryover effects that occurred from expanding an initial 8-item set.
