Implicit Association Tests (IATs) are supposed to measure associations between concepts. In order to achieve that aim, participants are required to assign individual stimuli to those concepts under time pressure in two different tasks. Previous research has shown that not only the associations of the concepts with each other, but also the stimuli's cross-category associations influence the observed reaction time difference between these tasks (i.e. the IAT effect). Little is known about adequate stimulus selection. In this article, we introduce a variant of the IAT, the Concept Association Task (CAT) in which the concepts themselves or synonyms of them are used as stimuli. Three experiments on Germans' attitudes towards foreigners yielded evidence for the convergent validity of the CAT: (1) it correlated well with other IAT versions; (2) it correlated higher with spontaneous attitude-related judgements than other IAT versions; and (3) it correlated with response-window priming, another implicit measure based on reaction times. Furthermore, we showed that the CAT yielded reasonable findings when other IAT versions appear to yield distorted ones.
内隐联想测验（IAT）旨在测量概念之间的关联。为实现这一目标，要求参与者在时间压力下，于两项不同任务中将个体刺激分配给这些概念。先前的研究表明，不仅概念之间的关联，而且刺激的跨类别关联都会影响这些任务之间观察到的反应时差异（即IAT效应）。关于合适的刺激选择知之甚少。在本文中，我们介绍了IAT的一种变体，即概念关联任务（CAT），其中概念本身或其同义词被用作刺激。关于德国人对外国人态度的三项实验为CAT的聚合效度提供了证据：（1）它与其他IAT版本相关性良好；（2）与自发的态度相关判断的相关性高于其他IAT版本；（3）与反应窗口启动相关，反应窗口启动是基于反应时的另一种内隐测量方法。此外，我们表明，当其他IAT版本似乎产生扭曲结果时，CAT能得出合理的结果。
