emphasis on inter-dependence, commonness, and openness to change in response to authority. These differences in self-perception show up when we attend to faces of familiar individuals. Chinese subjects, representative of a collectivistic and inter-dependent society, responded more quickly to seeing their boss’s face than seeing their own face. In contrast, American subjects responded more quickly to their own face than to any other person’s face, including that of their boss. Like Platt’s monkeys, therefore, we too place value on social information. Unlike Platt’s monkeys, our sense of value in the social domain is modulated by our cultural upbringing. This modulation, and the brain states that accompany it, shows up in direct comparisons of individuals who are motivated to attain high dominance status with those who are motivated to create equality. The American social psychologist Joan Chiao used survey information to establish two groups of individuals based on those who preferred to live in an egalitarian society and those who preferred a hierarchical society. These individuals then entered a brain scanner and viewed pictures of people experiencing pain. Two areas, both associated with the personal experience of pain and the perception of pain in others, were highly active. But these areas were less active in those who preferred hierarchies than those who preferred egalitarianism. This finding, as Chiao notes, is consistent with the idea that in an egalitarian society, empathy for others well-being is essential. In egalitarian societies, seeing someone who has less or is being harmed by another, should motivate a desire to redress the imbalance and reduce the harm. In a dog-eat-dog hierarchical society, where dominants outcompete subordinates and inequities are part of life, concern for those at the bottom is a sign of weakness. These results show how cultural influences can shape brain activity, leading some to develop deep desires for dominance and inequities
