研究人员经常尝试通过向不同组的参与者进行实验任务的两个或多个条件，并重点关注逐个条件的相互作用作为主要感兴趣的结果，来识别可能导致与神经状态或其他个体差异特征相关的表现差异的特定神经认知过程。讨论了这种方法的三个局限性，并提出了一种替代分析方法来克服这些局限性。该方法在两项独立研究中对 10 项认知任务的数据进行了分析，其中包括两项通常用于评估抑制方面的侧翼任务。 (C) 2010 Elsevier Inc. 保留所有权利。
Researchers frequently attempt to identify the specific neurocognitive processes that might be responsible for differences in performance associated with neurological status or other individual difference characteristics by administering two or more conditions of an experimental task to different groups of participants, and focusing on the group-by-condition interaction as the primary outcome of interest. Three limitations of this approach are discussed, and an alternative analytical method is proposed to overcome the limitations. The method is demonstrated in analyses of data from 10 cognitive tasks in two independent studies, including two flanker tasks which are often used to assess aspects of inhibition.
