Since Bleuler's early studies, the fact has become well established that stereotypy and mannerism in schizophrenia are not incoherent random gestures but have definite unconscious determinants and significance. This report deals with the elucidation of the meaning of a certain stereotyped behavior in discussions with a schizophrenic patient under amytal sedation and after electroshock treatment. Meyers feels that the stereotypy shows only the content and the precipitating factors of the psychotic process, but that the disease itself and the deep psychodynamics of the symptoms are not explained by it.
