Psychologists End Guantanamo Collaboration, Will No Longer Help Government In Interrogations

The nation's leading psychologist's association has voted to ban its members from taking part in interrogations at the prison at Guantanamo Bay, Cuba, and other military detention sites.

The ban means psychologists who are association members can't assist the U.S. military at these sites and can only work there for humanitarian purposes or with non-governmental groups, according to Stephen Soldz, a Boston psychologist. Soldz is founder of an ethics coalition that has long supported the ban.

Steven Reisner, a New York psychologist who's running for president of the association, said Thursday that members' votes were counted this week.
