动力系统理论和复杂性科学的结合为婴儿运动发育的研究带来了新的概念和方法。因此，这一纵向案例研究为描述婴儿肢体和发声行为的动力学特征提供了一种新的方法。记录了一个婴儿从51天到305天的发声和肢体运动。在每个录音日，加速计被放置在婴儿的四肢上，录音机被戴在孩子的胸前。使用非线性时间序列分析方法，如递归量化分析和Allan因子，我们量化了婴儿行为的稳定性和多尺度特性随年龄的变化，以及这些动态如何跨通道和效应器关联。我们观察到，这些动态的特殊变化在不同发育里程碑开始之前或同时发生。例如，发声动力学的最大变化发生在典型的喋喋不休之前。结果表明，非线性分析有助于理解婴幼儿行为不同方面的功能协同发展。
The pairing of dynamical systems theory and complexity science brings novel concepts and methods to the study of infant motor development. Accordingly, this longitudinal case study presents a new approach to characterizing the dynamics of infant limb and vocalization behaviors. A single infant's vocalizations and limb movements were recorded from 51-days to 305-days of age. On each recording day, accelerometers were placed on all four of the infant's limbs and an audio recorder was worn on the child's chest. Using nonlinear time series analysis methods, such as recurrence quantification analysis and Allan factor, we quantified changes in the stability and multiscale properties of the infant's behaviors across age as well as how these dynamics relate across modalities and effectors. We observed that particular changes in these dynamics preceded or coincided with the onset of various developmental milestones. For example, the largest changes in vocalization dynamics preceded the onset of canonical babbling. The results show that nonlinear analyses can help to understand the functional co-development of different aspects of infant behavior.
