Humans cross-culturally find infant faces both cute and highly likeable. Their so-called "baby schema" features have clear adaptive value by likely serving as an innate releasing mechanism that elicits caretaking behaviors from adults. However, we do not know whether experience with young children during social development might act to further facilitate this. Here we investigated the potential impact of having siblings on adult likeability judgments of children's faces. In this study, 73 adult men and women (40 with siblings and 33 without) were shown 148 different face pictures of young children (1 month to 6.5 years) and judged them for likeability. Results showed that both groups found faces of infants (<7 months) as equally likeable. However, for faces more than 7 months of age, whereas the no-sibling group showed a reduced liking for faces with increasing age, the sibling group found faces of all ages as equally likeable. Furthermore, for adults with siblings, the closer in age they were to their siblings, the stronger their likeability was for young children's faces. Our results are the first to show that having siblings can extend the influence of baby schema to children as well as infants.
人类在跨文化情境下都觉得婴儿的脸既可爱又非常讨人喜欢。他们所谓的“婴儿图式”特征具有明显的适应性价值，很可能作为一种先天释放机制，引发成年人的照顾行为。然而，我们不知道在社会发展过程中与幼儿的接触是否会进一步促进这一点。在这里，我们研究了有兄弟姐妹对成年人对儿童面孔喜爱度判断的潜在影响。在这项研究中，向73名成年男女（40名有兄弟姐妹，33名没有）展示了148张不同的幼儿（1个月至6.5岁）面部图片，并让他们对这些图片的喜爱程度进行评判。结果显示，两组都认为婴儿（小于7个月）的脸同样讨人喜欢。然而，对于7个月以上的面孔，没有兄弟姐妹的那组对年龄越大的面孔喜爱度越低，而有兄弟姐妹的那组则认为所有年龄段的面孔同样讨人喜欢。此外，对于有兄弟姐妹的成年人来说，他们与兄弟姐妹的年龄差距越小，就越喜欢幼儿的面孔。我们的研究结果首次表明，有兄弟姐妹可以将婴儿图式的影响扩展到儿童以及婴儿身上。
