Laboratory chimpanzees suffer stress similar to tortured humans

Posted 6 August 2008

A study of 116 chimpanzees who were used in medical research found that 95 per cent display distinctive patterns of behaviour that people show when suffering from post-traumatic stress disorder.

According to the study's author, Hope Ferdowsian – who has also evaluated the mental condition of human torture victims – these results demonstrate that ‘a chimpanzee's mind and emotional well-being are affected by experimentation in ways that parallel the psychological trauma experienced by victims of torture and other forms of abuse‘.
