However, from this type of work Freud was able to construct a system of psychoanalysis that demonstrates how mental energies could create physical symptoms. Freud began to believe that sexual impulses also greatly affected neurotic patients and began developing his psychosexual stages (oral, anal, etc.) of development in the infant and child. Freud, like Piaget, was greatly criticized for arguing that the years from birth to five are ones in which the adult personality is greatly shaped.

Oral Stage (0-1) Mouth Weaning (from breast
Anal Stage (1-3) Anus Toilet training
