All admissions during one year to the children's and adolescents' service of a large psychiatric hospital were directly questioned about belief in internalized phenomena. All who described such internal hallucinations were schizophrenic. Positive responses were obtained in twenty-six percent of schizophrenic children as opposed to thirteen percent of schizophrenic adolescents. The types of phenomena reported were internal voices urging deeds of good or evil; figures such as God, the devil, an angel, or a person, living or dead; animals; or such inanimate objects as clocks.
