Re: New article on cooperation the brain
The news release mentions that they played a prisoner's dilemma game and that all of the subjects were women. It did not say exactly what the payoffs were but they were awarded money. The article also said: Mutual cooperation was the most common outcome in games played with presumed human partners in both experiments, even though a player was maximally rewarded for defecting when the other player cooperated. When I play the prisoner's dilemma in class, I see very little cooperation. I do it with coins, face to face. If they both play heads, they get 3 each. 1 if they both play tails. If person A plays head while person B plays tails, A gets 0 and B gets 5. There are repeated trials and the students simultaneously open their hands to see the other's coin. After each trial they have to at least pretend that they might be changing their choice. Close hands, open again. It is only played for extra credit, not money. But I still see very little cooperation (heads). Over the years, I have not noticed that women are especially more cooperative than men. So it is very surprising to see the above quote. Maybe I am running the game wrong somehow and that is why I get little cooperation. If anyone has any suggestions, please email me. Cyril Morong
Re: New article on cooperation the brain
When I play the prisoner's dilemma in class, I see very little cooperation. I know one researcher who has repeated a trust game (not prisoner's dilemma) with many classes of students and groups of business men. He finds that students are remarkably untrustworthy and businessmen tend to give their trust quite frequently. He thinks that students are socially isolated from each other and have little experience in social worlds were trust is common, unlike business men. I wouldn't be surprised if there were a similar difference when you P.D. Can anybody confirm or reject this claim about students? Fabio

I teach at a community college, so the students probabl mix with each other less than they do at other colleges. If I recall correctly, I did obsverve more cooperation when I played this game at a small liberal arts college that I used to teach at. Cyril Morong

(Maybe not entirely*) I recall from my psych days that a notable thing about the prisoner's dilemma is that cooperation obtains. I got the impression that the result was robust. Perhaps a perusal of psych literature may shed some light on the subject--they have a long history in dealing with human subjects, so there might be something to learn. I'm stuck in a backwater (pop. 1,500) with a one-room library, so I can't help look. Sorry I can't be more helpful. jsh *I went to the Univ. of Oregon and found attitudes regarding considerate-ness significantly different from my native Michigan.

I should note that isolated doesn't mean literally isolated (college students do live in dorms!) but that acheivement in college is mainly through individual effort, while sucess in business really is a team effort.
