注视跟随，即重新引导一个人的视觉注意力去看另一个人所看到的东西的能力，是模仿、单词学习和心理理论的基础。先前的理论已经表明，人类婴儿的凝视跟随的发展是基本凝视跟随机制的产物，加上逐渐纳入几种不同的新机制，提高技能，如空间推理，以及使用眼睛方向信息和头部方向的能力。在本文中，我们提供了一种基于单一学习机制的替代解释。从一个不知道另一个生物体注视方向的含义的初始状态开始，我们的模型通过被放置在一个模拟环境中来学习跟随注视，在这个模拟环境中，一个成年看护者环顾四周。我们的婴儿模型与我们复制和详细分析的关键实验中测得的人类婴儿凝视跟随的发展相匹配。
Gaze following, the ability to redirect one's visual attention to look at what another person is seeing, is foundational for imitation, word learning, and theory-of-mind. Previous theories have suggested that the development of gaze following in human infants is the product of a basic gaze following mechanism, plus the gradual incorporation of several distinct new mechanisms that improve the skill, such as spatial inference, and the ability to use eye direction information as well as head direction. In this paper, we offer an alternative explanation based on a single learning mechanism. From a starting state with no knowledge of the implications of another organism's gaze direction, our model learns to follow gaze by being placed in a simulated environment where an adult caregiver looks around at objects. Our infant model matches the development of gaze following in human infants as measured in key experiments that we replicate and analyze in detail.
