Animals can be induced to cooperate if partners reciprocate and benefits accumulate

MINNEAPOLIS / ST. PAUL--Animals can be a pretty uncooperative lot. While species like lions and prairie dogs cooperate in some cases, scientists seldom know the costs and benefits of cooperative acts in the wild. In particular, scientists have long been interested in situations in which cooperating animals give up something now in order to develop a relationship that pays off in the long run. Experimental studies show, however, that animals don't usually cooperate in these cases; apparently, they are unwilling to pass up an immediate benefit in order to gain more in the long run. Now, experiments with blue jays at the University of Minnesota suggest that animals may be induced to cooperate when their opponent reciprocates by tit-for-tat behavior and rewards accumulate over a sequence of plays. The work, which will be published in the Dec. 13 issue of Science, suggests that these are among the factors guiding evolution of some animals--including humans--toward cooperative behavior.

"Our results suggest that the timing of the benefits of cooperation is really important," said lead investigator David Stephens, an associate professor of ecology, evolution and behavior in the College of Biological Sciences. "For example, suppose you want two toddlers to work together, and you reward good behavior at every turn. They're likely to soon fall back into bad behavior. But if they have to play nicely with each other for 10 trials before receiving a reward, then they are likely to do it."

Animals that behave in reciprocal (tit-for-tat) fashion and reap rewards only after a sequence of interactions may be those most likely to cooperate in nature, said Stephens. An animal that knows it must help out in order to receive help--perhaps by group hunting or defense of young--and that it must interact several times before realizing a reward--waiting minutes or hours before predators withdraw or prey is secured--is the best candidate to exhibit cooperative behavior.
