Psychological Test Adapted for Murderers

From Times Staff and Wire Reports

Scientists have adapted a standard psychological test that detects underlying prejudices to delve into the minds of psychopathic murderers. Serial killers can be adept at lying and deception, and may turn on the charm to confuse their interrogators. But researchers at Cardiff University in Wales say their test reveals implicit beliefs.

The test, which requires people to perform tasks and answer questions by computer, shows that psychopathic murderers have more positive reactions to violence than other offenders, which may help to expose those most likely to kill.
