Numerous studies have shown that infant facial cues significantly influence adults’ caregiving perceptions and behavior. Infant facial cues may be an adaptive mechanism for infants, as they may provide important information about the infant to a potential caregiver and evoke caregiving behavior. However, there is less research on whether all adults perceive and respond to infant cues similarly. Adults’ individual differences, by way of their personality traits, may give rise to different motivations, perceptions, and behaviors related to caregiving, and therefore may play an important role in how adults perceive and respond to infant cues. To investigate this, we recruited 142 adults from the community. We used direct and indirect paths to examine the associations between adults’ personality traits (using the HEXACO Personality Inventory), perceptions of infant facial cues (using 54 infant face stimuli and the Infant Facial Cue Rating Scale), and caregiving motivations (using the Hypothetical Adoption Paradigm). The results showed that higher Emotionality and Conscientiousness were directly related to higher hypothetical adoption preference. Honesty-Humility was indirectly associated with higher adoption preference through higher ratings of baby cues. These results suggest that adults’ personalities are related to their perceptions of infants and caregiving desires. The findings from this study can also lead to offering extra support to adults who work/interact with infants and children across various contexts (e.g., schools, daycares, healthcare facilities, playgrounds, hospitals) and whose personality traits may be related to less positive perceptions of infants and caregiving desires.

成年人的人格特质如何影响对婴儿面孔的知觉和反应？

大量研究表明，婴儿的面部暗示会显着影响成年人的护理观念和行为。婴儿的面部提示可能是婴儿的一种适应性机制，因为它们可能向潜在的看护人提供有关婴儿的重要信息并引起看护行为。但是，关于所有成年人是否对婴儿线索的感知和反应都相似的研究较少。成人的个性差异通过其人格特质可能会引起与护理有关的动机，看法和行为的不同，因此可能在成年人对婴儿线索的感知和反应中起重要作用。为了对此进行调查，我们从社区中招募了142名成年人。我们使用直接和间接路径来检查成年人的人格特质之间的关联（使用HEXACO人格量表），婴儿面部提示的感知（使用54个婴儿面部刺激和婴儿面部提示评级量表）以及护理动机（使用假设采用范式）。结果表明，较高的情绪和责任感与较高的假设采用偏好直接相关。诚实-谦卑与更高的婴儿暗示等级间接地与更高的收养偏好相关。这些结果表明，成年人的性格与他们对婴儿的看法和照顾愿望有关。这项研究的发现还可以为在各种情况下（例如，学校，日托，医疗机构，游乐场，
