在最近的尝试中，建立了一个老年人智力迟钝的综合模型，在回归分析中，反应时间（RT）数据来自大量研究，涵盖了广泛的快速决策任务。这些荟萃分析的结果随后被用来支持这样的结论，即老年人的心理处理速度有一个普遍的、成比例的下降，这对心理的所有要素都有同样的影响。我们提出了一系列类似的回归分析，其中包括RT和事件相关脑电位的P300成分的潜伏期。这些分析的结果表明，在老年人中，有一些心理处理的要素可能会逐渐减慢，而不是成比例地减慢。此外，结果提出了一些关于解释元回归分析的逻辑问题。（PsycInfo数据库记录(c) 2022 APA，版权所有）
In recent attempts to formulate an integrative model of mental slowing in elderly persons, regression analyses have been done in which reaction-time (RT) data from a large number of studies spanning a broad range of speeded decision-making tasks were combined. The results of these meta-analyses were then used to support the conclusion that there is a generalized, proportional decline in mental processing speed among elderly adults that affects all elements of mentation equally. We present a series of similar regression analyses in which both RT and the latency of the P300 component of the event-related brain potential are included. The results of these analyses indicate that there are elements of mental processing that may be slowed additively, not proportionately, in older persons. Furthermore, the results raise some questions about the logic underlying the interpretation of the meta-regression analysis.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
