背景:在人的内部,过程和表现的跨时间变化是人类功能的所有方面所固有的。目的:本文首先简要介绍了个体内动力的分类。存在适应性和非适应性类型的个体内变异,它们在不同的时间尺度上以不同程度的可逆性展开,涉及单一的或系统的功能。方法:关于衰老和一种特定类型的个体内变异的经验结果,即减弱的加工稳健性,然后在认知和感觉运动功能方面提出。结果:在这两个功能领域,老年人表现出不那么强健的功能,他们的认知、行走和姿势控制表现出更多的周至周、日至日或逐次试验的波动。结论:目前,认知和感觉运动功能中加工稳健性减弱的原因尚不清楚。神经计算模型是探索神经信息处理保真度老化与认知和感觉运动过程之间三方关系的有用工具。
Background: Within-person, across-time variations in processes and performance are intrinsic to all aspects of human functioning. Objective: This article starts with a brief taxonomy of intraindividual dynamics. There are adaptive as well as non-adaptive types of intraindividual variations that unfold with different degrees of reversibility on different time scales and involve either single, or systems of, functions. Methods: Empirical findings regarding aging and a specific type of intraindividual variation, namely attenuated processing robustness, are then presented with respect to cognitive and sensorimotor functioning. Results: In both domains of functioning, old adults exhibit less robust functioning with a greater amount of week-to-week, day-to-day, or trial-by-trial fluctuations in their cognitive, walking, and postural control performances. Conclusion: Currently, the causes for the attenuation of processing robustness in cognitive and sensorimotor functioning are not well understood. Neurocomputational models are useful tools for exploring the tripartite relationships between the aging of neural information-processing fidelity, and cognitive, and sensorimotor processes.
