The sequence of training and testing in the three behavioral tasks across the lifespan of the rats.

Intravenous Self-Administration (n = 32)		Nicotine Discrimination (n = 12)		Conditioned Taste Aversion (n = 24)
Phase	PND	Phase	PND	Phase	PND
Food training and Surgery	59–80	Response training	82–102	Water restriction	60–66
FR Acquisition	81–105	Discrimination training	103–167	Flavor conditioning	67–74
FR Dose-response	108–140	Dose-response	168–187	Choice test	75–76
PR Acquisition	143–154
PR Dose-response	157–175

Rats from all experiments were exposed to the same AIE regimen on PND 28–53 (see text for details). PND, postnatal day; FR, fixed ratio; PR, progressive ratio.
