认知加工速度研究中常用的实验和统计方法

STAPLE EXPERIMENTAL AND STATISTICAL METHODS IN PROCESSING SPEED RESEARCH

认知加工速度理论是解释年龄与认知老年化现象的理论之一,也是近年来心理学研究中的热点之一。该文从理论要点、实验设计、指标选择和统计分析手段四个方面对认知加工速度的研究进行了回顾。在阐述理论要点的基础上,介绍了常用的实验指标和选择指标的标准,以及一些常用的统计分析手段。作者认为除了深入理解理论之外,谨慎地设计实验方案、选择适当的实验指标,以及采用恰当的统计手段都是研究得以顺利进行的必要保障。

Processing speed theory is one of the theories trying to explain the relation between age and recognition aging, and it is one of the hotspots of later-year psychology researches. This article reviewed the researches on processing speed theory from four aspects: the theory, the experimental design, the test and the statistic method. Based on the expatiation on the theory, it introduced the criterion of test choosing, and the staple tests and statistic methods. The author believes that to do a successful research must comprehend the theory deeply, design the experiments carefully, choose proper tests and use appropriate statistic methods.
