The papers in this issue are excellent examples of the many uses of measuring reaction time in the exploration of nervous system pathologies. In our commentary we consider mental chronometry as a field that seeks to measure the time course of mental operations in the human nervous system. We draw upon diverse methods such as neuroimaging, electrical recording and reaction time to illustrate the use of chronometry in conjunction with anatomy and genetics to approach both normal individual differences and pathologies. The goal is to examine general and specific changes in neural networks that underlie both variations in normal function and changes due to pathology. Although much remains to be done along these lines, it is now possible to see how the various chronometric contributions outlined in this special issue can converge to provide a basis for improved understanding of the genetic and experiential basis of cognitive and emotional processes.
本期的论文是测量反应时间在神经系统病理学探索中的多种用途的杰出范例。在我们的评论中，我们将心理计时法视为一个旨在测量人类神经系统中心理操作时间进程的领域。我们借鉴了多种方法，如神经成像、电记录和反应时间，来说明计时法与解剖学和遗传学相结合在研究正常个体差异和病理学方面的应用。目标是研究神经网络中普遍和特定的变化，这些变化是正常功能变异和病理导致的变化的基础。尽管沿着这些方向仍有许多工作要做，但现在已经可以看到本期特刊中概述的各种计时贡献如何汇聚在一起，为更好地理解认知和情感过程的遗传和经验基础提供依据。
