这项研究使用自然、急性、传染性疾病患者的面部照片，研究了儿童对疾病的回避和识别的发展。在美国的一项样本中，57名4至5岁的儿童(46%为男性，70%为白人)、52名8至9岁的儿童(26%为男性，62%为白人)和51名成年人(59%为男性，61%为白人)避开并识别病态面孔(DS从0.38到2.26)。回避和再认都随着年龄的增长而提高。有趣的是，4至5岁儿童对病态面孔的回避与他们的识别呈正相关，这表明在这些新兴技能上存在稳定的个体差异。总而言之，这些发现与假设的不成熟但功能和灵活的行为免疫系统在发育早期出现是一致的。确定儿童疾病感知的特征可能有助于设计改善健康的干预措施。
This study examined the development of children's avoidance and recognition of sickness using face photos from people with natural, acute, contagious illness. In a U.S. sample of fifty‐seven 4‐ to 5‐year‐olds (46% male, 70% White), fifty‐two 8‐ to 9‐year‐olds (26% male, 62% White), and 51 adults (59% male, 61% White), children and adults avoided and recognized sick faces (ds ranged from 0.38 to 2.26). Both avoidance and recognition improved with age. Interestingly, 4‐ to 5‐year‐olds' avoidance of sick faces positively correlated with their recognition, suggesting stable individual differences in these emerging skills. Together, these findings are consistent with a hypothesized immature but functioning and flexible behavioral immune system emerging early in development. Characterizing children's sickness perception may help design interventions to improve health.
