The Stroop task has a long-standing history in psychological research and diagnostics, and many variants have emerged. Computerized versions have recently gained popularity because of their applicability in brain-imaging studies. It remains unclear, however, whether computerized versions are content valid with reference to the original task. We compare the performance in the original task with two computerized versions. All three versions show high test-retest reliability and are able to elicit interference effects, but to varying degrees. However, performances in the computerized versions and in the original task do not correlate. The transition from oral to manual response and from listed to single stimulus presentation seems not only to diminish the interference effect, but also to alter its nature in such a way that it no longer looks genuinely "Stroop-like". These findings have important clinical implications on the use and interpretation of computerized Stroop tasks in children and adults.
斯特鲁普任务在心理研究和诊断中有着悠久的历史，并且已经出现了许多变体。由于其在脑成像研究中的适用性，计算机化版本最近变得越来越流行。然而，目前尚不清楚计算机化版本在参照原始任务时是否具有内容有效性。我们比较了原始任务与两种计算机化版本的表现。所有三个版本都表现出高度的重测信度，并且能够引发干扰效应，但程度不同。然而，计算机化版本和原始任务的表现并不相关。从口头到手动反应的转变，以及从列表呈现到单个刺激呈现的转变，不仅似乎降低了干扰效应，而且还改变了其性质，使其不再真正具有“斯特鲁普效应”。这些发现对儿童和成人使用和解释计算机化斯特鲁普任务具有重要的临床意义。
