Cognitive control is one of the most fundamental aspects of human life. Its ageing is an important contemporary research area due to the needs of the growing ageing population, such as prolonged independence and quality of life. Traditional ageing research argued for a global decline in cognitive control with age, typically characterised by slowing processing speed and driven by changes in the frontal cortex. However, recent advances questioned this perspective by demonstrating high heterogeneity in the ageing data, domain-specific declines, activity changes in resting state networks, and increased functional connectivity. Moreover, improvements in neuroimaging techniques have enabled researchers to develop compensatory models of neural reorganisation that helps negate the effects of neural losses and promote cognitive control. In this article on typical ageing, we review recent behavioural and neural findings related to the decline in cognitive control among older adults. We begin by reviewing traditional perspectives and continue with how recent work challenged those perspectives. In the discussion section, we propose key areas of focus for future research in the field.
认知控制是人类生活最基本的方面之一。由于老年人口不断增长的需求,如延长独立生活时间和提高生活质量,认知控制的老化是当代一个重要的研究领域。传统的老化研究认为,随着年龄的增长,认知控制会全面衰退,其典型特征是处理速度减慢,且由额叶皮质的变化所驱动。然而,最近的进展对这一观点提出了质疑,这些进展表明老化数据存在高度异质性、特定领域的衰退、静息态网络的活动变化以及功能连接性增加。此外,神经成像技术的进步使研究人员能够开发神经重组的补偿模型,有助于抵消神经损失的影响并促进认知控制。在这篇关于典型老化的文章中,我们回顾了与老年人认知控制衰退相关的近期行为和神经学研究结果。我们首先回顾传统观点,然后继续探讨近期研究如何挑战了这些观点。在讨论部分,我们提出了该领域未来研究的关键重点领域。
