Which of the following was not a factor involved in the study conducted by psychologist David Rosenhan?

In Rosenhan’s study, eight healthy people entered psychiatric hospitals after reporting that they heard a voice saying words such as “empty,” “hollow,” or “thud.” Once admitted, they behaved normally and gave truthful information about their histories, but staff continued to regard their ordinary behavior as symptoms. They were eventually discharged with a diagnosis, not released without one, so choice B was not a factor.
