[Protection of a naive rat from consuming a solution by a congeneric rat which has learned to refuse it]
Abstract:
When a rat drinks a solution of lithium chloride, it learns once and for all to refuse solutions of similar (salty) taste. In the presence of a naive rat, rats treated with lithium chloride develop an "eviction" behaviour which makes them push the naive rat away from the saline. The result is a "protection" of the naive rat, made apparent from a fall in the consumption of the solution offered.
