Pearson reviews some of the manifestations of weakness of ego as they are observed in the psychotic child. These include dread of the strength of the instincts; vagueness of ego boundaries and defectiveness of the body image; too much devotion to habits and routine as compared with object relationship; unusual gracefulness and fluidity of the body movements; and hypersensitivity to some sensory stimuli such as loud noises. Much use of intellectualism in a little child may also be a sign of ego weakness. An understanding of signs and symptoms of a weakness of ego in the psychotic child and adult may contribute to our recognition and understanding of ego weakness in the more nearly normal individual.
