Since birth, infants discriminate the biological motion (BM) revealed by point-light displays (PLDs). To date, no studies have explored whether newborns differentiate BM that approaches rather than withdraws from them. Yet, approach and withdrawal are two fundamental motivations in the socio-emotional world, key to developing empathy and prosocial behavior. Through a looking-behavior paradigm, we demonstrated that a few hours after birth, a human figure approaching attracted more visual attention than a human figure receding, showing that newborns are attuned to PLDs of others moving toward rather than walking away from them. Further, a withdrawing body appears to be less attractive than withdrawing scrambled points. Altogether, these observations support the existence of an early predisposition toward social closeness that might have its roots in an evolutionary perspective.

新生儿的对接近和退出生物运动的感知：一个亲密的故事

自出生以来，婴儿就能辨别点光显示器（PLD）显示的生物运动（BM）。迄今为止，还没有研究探讨新生儿是否能够区分接近而不是远离的骨髓。然而，接近和退出是社会情感世界的两个基本动机，是发展同理心和亲社会行为的关键。通过观看行为范式，我们证明了出生后几个小时，一个接近的人比一个远离的人吸引了更多的视觉注意力，这表明新生儿能够适应其他人靠近而不是远离的 PLD。此外，撤回机构似乎不如撤回扰乱积分那么有吸引力。总而言之，这些观察结果支持了早期社会亲密倾向的存在，这可能源于进化的观点。
