The Delis-Kaplan Executive Function System (D-KEFS) Color-Word Interference Test (CWIT) was designed to improve upon the Stroop task by including an inhibition/switching trial, which was designed to be more difficult than the inhibition trial in terms of time to completion and number of errors. The D-KEFS standardization data support this view. However, in clinical practice, we have noticed that many people perform better on the inhibition/switching trial than the inhibition trial. We examined the prevalence and correlates of this atypical performance pattern on the CWIT. Patients seeking outpatient neuropsychological evaluation (n = 119) completed the CWIT as part of a larger test battery. About 57.1% of patients demonstrated an atypical pattern of performance for either completion time or errors. Patients with an atypical pattern for completion time were significantly slower at color naming and word reading than patients with a typical pattern. Patients with an atypical pattern for errors performed better on measures of learning and semantic verbal fluency than patients with a typical pattern. A majority of patients in our sample exhibited atypical performance on the CWIT, and some preliminary correlates of this pattern might aid clinical interpretation.
德利斯科尔-卡普兰执行功能系统（D-KEFS）颜色-词语干扰测试（CWIT）旨在通过包含抑制/转换试验来改进斯特鲁普任务，该试验在完成时间和错误数量方面比抑制试验更难。D-KEFS 的标准化数据支持这种观点。然而，在临床实践中，我们注意到许多人在抑制/转换试验中的表现优于抑制试验。我们检查了 CWIT 上这种非典型表现模式的流行率和相关性。接受门诊神经心理评估的患者（n=119）作为更大的测试组合的一部分完成了 CWIT。大约 57.1%的患者在完成时间或错误方面表现出非典型的模式。完成时间出现非典型模式的患者在颜色命名和单词阅读方面明显比典型模式的患者慢。在错误方面表现出非典型模式的患者在学习和语义流畅性方面的表现优于典型模式的患者。我们样本中的大多数患者在 CWIT 上表现出非典型的表现，这种模式的一些初步相关性可能有助于临床解释。
