Abstract
The adrenergic stimulants, amphetamine, ephedrine, and epinephrine, fa-ciliated following behavior up to 18 hours of age and interfered with it at later ages. The cholinergic stimulant, neostigmine, had no statistically significant effect, while atropine, a cholinergic blocking agent and central stimulant, facilitated at 8 hours and interfered at all later ages tested. Hexamethonium, which antagonizes the nicotinic action of acetylcholine at the autonomic ganglia, facilitated at 8 and 24 hours and had no interfering effects. Similar effects were observed under the influence of ergotamine, a vasoconstrictor and adrenergic blocking agent. These drugs affect both the initial imprinting performance and the acquisition of the following behavior.
