The development of action and perception, and their relation in infancy is a central research area in socio-cognitive sciences. In this Perspective Article, we focus on the developmental variability and continuity of action and perception. At group level, these skills have been shown to consistently improve with age. We would like to raise awareness for the issue that, at individual level, development might be subject to more variable changes. We present data from a longitudinal study on the perception and production of contralateral reaching skills of infants aged 7, 8, 9, and 12 months. Our findings suggest that individual development does not increase linearly for action or for perception, but instead changes dynamically. These non-continuous changes substantially affect the relation between action and perception at each measuring point and the respective direction of causality. This suggests that research on the development of action and perception and their interrelations needs to take into account individual variability and continuity more progressively.
动作与感知的发展及其在婴儿期的关系是社会认知科学的一个核心研究领域。在这篇观点文章中，我们关注动作与感知的发展变异性和连续性。在群体层面，这些技能已被证明会随着年龄的增长而持续提高。我们希望提高人们对以下问题的认识：在个体层面，发展可能会经历更多可变的变化。我们展示了一项关于7、8、9和12个月大婴儿对侧够物技能感知与产生的纵向研究数据。我们的研究结果表明，动作或感知的个体发展并非呈线性增加，而是动态变化的。这些非连续变化在每个测量点都极大地影响了动作与感知之间的关系以及各自的因果方向。这表明，关于动作与感知发展及其相互关系的研究需要更全面地考虑个体变异性和连续性。
