Abstract
In a standard conditioned taste-aversion methodology, rats (Rattus norvegicus) ingested a novel saccharin solution and then received intragastric infusions or intraperitoneal injections of lithium chloride (LiCl) after a delay of either 0, 30, or 60 min. The two methods of administration of LiCl were found to produce equivalent aversions as assessed over three extinction trials. Both methods of administration showed a delay of reinforcement effect, that is, both of the zero-delay conditions resulted in enhanced suppression of drinking on the first extinction trial relative to the 30-and 60-min-delay conditions, which did not differ according to delay or method of administration.
