You too can be a loser at the game of social ostracism

Now you can play Cyberball — a computer game that psychology researchers use to study the effects of social ostracism and hurt feelings. Normally, the game is played by test subjects who are hooked up to some kind of brain scanning system and who are told that they are playing against other test subjects in other rooms. In reality, they (and now you!) are playing against a computer program that is designed to exclude you and make you feel unwelcome. Why would someone design such a thing? For science! Of course.
