个人重视有助于决策的信息。当社会互动使决策过程复杂化时，获取他人的信息应该特别有价值[1]。在灵长类社会中，亲属关系、支配地位和生殖状态调节着社会互动[2，3]，因此应该系统地影响社会信息的价值，但这从未得到证明。在这里，我们表明，猴子的差异价值的机会，以获得视觉信息的特定类别的社会形象。雄性恒河猴牺牲了液体，以获得观察雌性恒河猴的机会。和地位高的猴子的脸，但需要流体多支付，以查看低地位的猴子的脸。社会价值是高度一致的科目，独立于特定的图像显示，只有部分预测多久的科目选择查看每个图像。这些数据表明，视觉定向决策反映了视觉信息的特定社会内容，并提供了第一个实验证据表明，猴子自发地歧视他人的图像的社会地位的基础上。
Individuals value information that improves decision making. When social interactions complicate the decision process, acquiring information about others should be particularly valuable [1]. In primate societies, kinship, dominance, and reproductive status regulate social interactions [2, 3] and should therefore systematically influence the value of social information, but this has never been demonstrated. Here, we show that monkeys differentially value the opportunity to acquire visual information about particular classes of social images. Male rhesus macaques sacrificed fluid for the opportunity to view female perinea. and the faces of high-status monkeys but required fluid overpayment to view the faces of low-status monkeys. Social value was highly consistent across subjects, independent of particular images displayed, and only partially predictive of how long subjects chose to view each image. These data demonstrate that visual orienting decisions reflect the specific social content of visual information and provide the first experimental evidence that monkeys spontaneously discriminate images of others based on social status.
