  abstract =	 {In this work, we present a simulation study drawn
                  upon a famous ethological example: food-sharing
                  habit of vampire bats in Central America. A norm of
                  reciprocity is introduced when agents are expected
                  to exhibit a cooperative behavior under serious
                  environmental strictures (infrequent but lethal food
                  scarcity). We compare different agents'
                  architectures (with different levels of cognitive
                  complexity) in the evolution of food-sharing habit
                  and we analyze their performances against the
                  presence of cheaters in the population. The
                  experiments are aimed at studying the role of
                  cognitive mediators (i.e. goals) in spreading
                  altruism, described as a purposeful action.},
