Famous quotes containing the word development:

    The American has dwindled into an Odd Fellow—one who may be known by the development of his organ of gregariousness.
    Henry David Thoreau (1817–1862)

    Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.
    Lawrence Kutner (20th century)

    Understanding child development takes the emphasis away from the child’s character—looking at the child as good or bad. The emphasis is put on behavior as communication. Discipline is thus seen as problem-solving. The child is helped to learn a more acceptable manner of communication.
    Ellen Galinsky (20th century)
