The idea that our perceptions in the here and now are influenced by prior events and experiences has recently received substantial support and attention from the proponents of the Predictive Processing (PP) and Active Inference framework in philosophy and computational neuroscience. In this paper we look at how perceptual experiences get off the ground from the outset, in utero. One basic yet overlooked aspect of current PP approaches is that human organisms first develop within another human body. Crucially, while not all humans will have the experience of being pregnant or carrying a baby, the experience of being carried and growing within another person’s body is universal. Specifically, we focus on the development of minimal selfhood in utero as a process co-embodiment and co-homeostasis, and highlight their close relationship. We conclude with some implications on several critical questions fuelling current debates on the nature of conscious experiences, minimal self and social cognition.

我们此时此地的感知受到先前事件和经历影响的观点最近得到了哲学和计算神经科学中预测处理（PP）和主动推理框架支持者的大力支持和关注。在本文中，我们研究了感知体验如何从一开始就在子宫内开始发挥作用。当前 PP 方法的一个基本但被忽视的方面是，人类有机体首先在另一个人体中发育。至关重要的是，虽然并非所有人类都会有怀孕或生孩子的经历，但在另一个人的身体内被怀抱和成长的经历是普遍的。具体来说，我们关注子宫内最低自我的发展作为一个过程的共同体现和共同稳态，并强调它们的密切关系。最后，我们对几个关键问题提出了一些启示，这些问题引发了当前关于意识体验、最低自我和社会认知的本质的争论。
