Values are generally received through cultural means, especially diffusion and transmission or socialization from parents to children. Parents in different cultures have different values. For example, parents in a hunter–gatherer society or surviving through subsistence agriculture value practical survival skills from a young age. Many such cultures begin teaching babies to use sharp tools, including knives, before their first birthdays. Italian parents value social and emotional abilities and having an even temperament. Spanish parents want their children to be sociable. Swedish parents value security and happiness. Dutch parents value independence, long attention spans, and predictable schedules. American parents are unusual for strongly valuing intellectual ability, especially in a narrow "book learning" sense. The Kipsigis people of Kenya value children who are not only smart, but who employ that intelligence in a responsible and helpful way, which they call "ng'om". Luos of Kenya value education and pride which they call "nyadhi".
