Young (7-day-old), middle-aged (28-day-old), and old (49-day-old) Drosophila melanogaster were compared for acquisition, then extinction, of excitatory conditioning of the Proboscis Extension Response. The contribution of nonassociative processes (sucrose-induced Central Excitatory State, Pseudoconditioning) in the elicitation of conditioned responses was simultaneously assessed. Old flies displayed a faster and stronger acquisition than middle-aged ones, whereas no significant acquisition was stated in young flies. The influence of nonassociative processes on the acquisition was of minor importance, even though Central Excitatory State increased with age. Old flies proved also to be the slowest to extinguish. Because nonassociative contami...
