Yet it is a remarkable fact that at birth the pain reflex is wanting.

His whole life up to about the fourth month turns upon his organic and vegetative needs.

At three months the young child will forget his mother or nurse after a very few days.

Attention begins to arise about the end of the first quarter year, appearing first in response to bright lights and loud sounds, and being for a considerable time purely reflex, drawn here and there by the successive impressions which the environment makes.

With lights and sounds, however, movements also attract the infant's attention very early; and the passage from reflex attention to a sort of vague interest seems to arise first in connection with the movements of the persons about him.
