The question of whether humans react differentially to face-like versus non face-like light stimulation in the prenatal period has been much discussed, but to date has remained unresolved. In this feasibility study we have come closer to understanding fetal vision. In contrast to other studies examining fetal reactions to prenatal light stimulation, we controlled maternal factors known to affect fetal neurodevelopment; including maternal mental health and attachment. We found that, for fetuses at 33 weeks gestation, maternal mental health (anxiety and depression), and fetal growth factors (femur length) all had a significant effect on fetal reactivity to face-like compared to a non-face-like control light stimulus. This calls into question some previously published results. We discuss implications of these findings in terms of the development of fetal visual perception.
人类在胎儿期对类似面孔的光刺激与非类似面孔的光刺激是否会有不同反应，这个问题已经讨论了很多，但迄今为止仍未得到解决。在这项可行性研究中，我们对胎儿视觉有了更深入的了解。与其他研究胎儿对产前光刺激反应的研究不同，我们控制了已知会影响胎儿神经发育的母体因素，包括母体的心理健康和依恋。我们发现，对于 33 周的胎儿，母体的心理健康（焦虑和抑郁）和胎儿的生长因素（股骨长度）都对面部类似的光刺激与非面部类似的控制光刺激对胎儿的反应有显著影响。这使得一些之前发表的结果受到了质疑。我们根据这些发现对胎儿视觉感知的发展进行了讨论。
