Zitat :: Abstract

We conducted three experiments to examine variables that might inﬂuence the longevity of socially induced food preferences in Norway rats. The duration of social inﬂuence on the food choices of 42-day-old rats (1) increased with both increasing numbers of demonstrators and increasing numbers of demonstrations by a single demonstrator, (2) varied with the temporal distribution of demonstrations, but (3) did not vary with the age of demonstrators. The results suggest that a single episode of social learning produces short-term, but not long-term, eVects on a Norway rat’s food choices
