 The aim of this study is to show presence of cognitive and emotional factors on the beginning and persistence of auditory hallucinations in non-psychotic children. Investigators will describe a significant link between this factors and hallucinations in a sample of non-psychotic children. The results of this sample will be comparing to another group of children of the same age, sex and diagnosis, but without hallucination.
