Biases favoring the wealthy are ubiquitous, and they support and bolster vast resource inequalities across individuals and groups; yet, when these biases are acquired remains unknown. In Experiments 1 through 5 (Total N = 232), using multiple methods, we found that 14- to 18-month-old infants track individuals' wealth (Experiments 1-5), prefer and selectively help rich (vs. poor) individuals (Experiments 2 and 3), and negatively evaluate poor individuals (Experiments 4 and 5). In two subsequent experiments with 11- to 13-month-old infants (Total N = 65), however, we find no evidence of preferences for rich (vs. poor) individuals (Experiment 6) or differential evaluations of rich and poor people (Experiment 7). Together, these results demonstrate that in the second year of life, wealth emerges as a central and robust dimension of evaluation that guides social decision making.

富人和穷人：婴儿利用财富来指导社会行为和评价。


有利于富人的偏见无处不在，它们支持和加剧了个人和群体之间巨大的资源不平等；然而，这些偏见何时形成仍不得而知。在实验 1 至 5（总 N = 232）中，使用多种方法，我们发现 14 至 18 个月大的婴儿追踪个人的财富（实验 1-5），更喜欢并有选择地帮助富人（相对于穷人） （实验2和3），并对贫困个体进行负面评价（实验4和5）。然而，在随后对 11 至 13 个月大的婴儿进行的两项实验中（总 N = 65），我们没有发现任何证据表明对富人（与穷人）个体的偏好（实验 6）或对富人和穷人的不同评价（实验7）。总之，这些结果表明，在生命的第二年，财富成为指导社会决策的核心而有力的评估维度。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
