Average number of sessions (Least Square Means ± SE) required by hens to advance to the subsequent phase during acquisition of a Go/No-Go task (phase 3-5). Learning criterion to proceed to the next phase was set at 75% of rewards obtained over two consecutive sessions. Different letters indicate significant differences (Pā<ā0.05).
