Social psychologists have become increasingly interested in the influence of culture on social cognition. Although people of all cultures use schemas to understand the world, the content of schemas has been found to differ for individuals based on their cultural upbringing. For example, one study interviewed a Scottish settler and a Bantu herdsman from Swaziland and compared their schemas about cattle. Because cattle are essential to the lifestyle of the Bantu people, the Bantu herdsmen's schemas for cattle were far more extensive than the schemas of the Scottish settler. The Bantu herdsmen was able to distinguish his cattle from dozens of others, while the Scottish settler was not.
