9和12周大的婴儿（N = 140）谁是平静或哭泣坐在面对研究人员3.5分钟。研究人员凝视着婴儿的眼睛与微笑的脸，或看着婴儿的额头以上。她通过注射器或奶嘴输送了12%的蔗糖溶液，或者她没有输送任何东西。在暴露期之后。母亲把婴儿抱在肩上。当婴儿面对同一个研究人员和一个陌生人时，记录婴儿的注视方向。甜味和眼神接触的融合是必要的，足以让9周和12周的婴儿形成对研究人员的偏好。哭泣的婴儿从不这样做，即使眼神接触和甜味阻止了哭泣。不同的视觉味觉组合引起的意想不到的情感状态，并在调解面对团队和偏好的认知机制的背景下进行了讨论，所涉及的近端机制。以及面部识别的进化意义。
Nine and 12-week-old infants (N = 140) who were either calm or crying sat facing a researcher for 3.5 min. The researcher gazed into the infant's eyes with a smiling face or looked above the infant's forehead. She delivered a 12% sucrose solution via a syringe or a pacifier, or she did not deliver anything. After the exposure period. the mother held her infant over her shoulder. Infant gaze direction was recorded while the infant faced the same researcher and a stranger. The confluence of sweet taste and eye contact was necessary and sufficient for calm 9- and 12-week-olds to form a preference for the researcher. Crying infants never did so, even though eye contact and sweet taste arrested crying. Different visual-gustatory combinations induced unanticipated affective states and are discussed within the contexts of cognitive mechanisms that mediate face teaming and preference, the proximate mechanisms involved. and the evolutionary significance of face recognition.
