Both selective attention and response inhibition can be assessed through the Stroop task and the Go/NoGo task (Go/NoGo). The color-word matching Stroop task (cwmStroop) differs from the traditional Stroop task in ways that make it easy to administer, and it enables the examiners to analyze reaction time. It is expected that the cwmStroop and Go/NoGo tasks will be useful as clinical assessments for children with developmental disorders and in combination with functional magnetic resonance imaging studies. The objectives of this study were to elucidate the pattern of developmental change in cwmStroop scores and Go/NoGo scores and to determine whether and how cwmStroop scores are related to Go/NoGo scores. The subjects consisted of 108 healthy Japanese children aged 6-14 years. We found that cwmStroop and Go/NoGo scores displayed clear developmental changes between 6 and 14 years of age. The children's scores on the 2 tasks followed different developmental courses, however, and the correlation between scores on the two tasks was weak on the whole. These results indicate that the cwmStroop and Go/NoGo tasks tap different aspects of selective attention and response inhibition. Therefore it is expected that the combination of both tests will be useful in the multifaceted assessment of selective attention and response inhibition in childhood.
选择性注意和反应抑制都可以通过斯特鲁普任务（Stroop task）和“Go/NoGo”任务（Go/NoGo）来评估。颜色-单词匹配斯特鲁普任务（cwmStroop）在某些方面与传统斯特鲁普任务不同，这些不同之处使得它易于实施，并且能让检查者分析反应时间。预计cwmStroop任务和“Go/NoGo”任务将作为对发育障碍儿童的临床评估手段，并与功能磁共振成像研究相结合使用。本研究的目的是阐明cwmStroop分数和“Go/NoGo”分数的发育变化模式，并确定cwmStroop分数是否以及如何与“Go/NoGo”分数相关。研究对象包括108名6至14岁的健康日本儿童。我们发现，cwmStroop分数和“Go/NoGo”分数在6至~14岁之间呈现出明显的发育变化。然而，儿童在这两项任务上的分数遵循不同的发育过程，而且两项任务分数之间的相关性总体较弱。这些结果表明，cwmStroop任务和“Go/NoGo”任务涉及选择性注意和反应抑制的不同方面。因此，预计这两项测试的组合将有助于对儿童期选择性注意和反应抑制进行多方面评估。
