一般慢化(GS)理论通常通过荟萃分析来检验,该模型将老年人的平均潜伏期作为年轻人平均潜伏期的函数。普通最小二乘(OLS)回归不适用于此目的,因为它无法解释多任务响应时间(RT)数据的嵌套结构。层次线性模型(HLM)是分析此类数据的另一种方法。使用迭代认知任务的21项研究数据的OLS分析支持GS;然而,HLM分析表明,在不同的实验任务中,记忆扫描的慢化程度比视觉搜索和心理旋转任务的慢化程度要低,这表明在不同的实验任务中,慢化程度存在显著差异。作者得出结论,HLM比OLS方法更适合于RT数据的元分析和检验GS理论。(PsycINFO数据库记录(c) 2016 APA,版权所有)
General slowing (GS) theories are often tested by meta-analyses that model mean latencies of older adults as a function of mean latencies of younger adults. Ordinary least squares (OLS) regression is inappropriate for this purpose because it fails to account for the nested structure of multitask response time (RT) data. Hierarchical linear models (HLM) are an alternative method for analyzing such data. OLS analysis of data from 21 studies that used iterative cognitive tasks supported GS; however, HLM analysis demonstrated significant variance in slowing across experimental tasks and a process-specific effect by showing less slowing for memory scanning than for visual-search and mental-rotation tasks. The authors conclude that HLM is more suitable than OLS methods for meta-analyses of RT data and for testing GS theories.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
