计数Stroop是一个经过验证的Stroop任务变体。它最初被设计为一种功能性磁共振成像（fMRI）任务，用于识别控制认知和注意力的大脑区域（背前中扣带皮层（daMCC）和背外侧前额叶皮层（DLPFC）），它已被用于研究健康志愿者的认知，并用于识别神经精神疾病（如注意缺陷多动障碍（ADHD））的功能性大脑异常。在计数过程中，受试者按按钮报告-按下屏幕上出现的单词数（1到4），而不管单词的含义。中性词控制试验包含单一语义类别的常见动物（例如，“狗”写了三次），而干扰试验包含与正确反应不一致的数字词（例如，“二”写了四次）。计数Stroop可以在每个受试者大约20分钟内完成，可以离线使用（行为表现），也可以与fMRI、正电子发射断层扫描、事件相关电位、脑磁图或颅内记录一起使用。
The counting Stroop is a validated Stroop task variant. Initially designed as a functional magnetic resonance imaging ( fMRI) task for identifying brain regions subserving cognition and attention ( dorsal anterior midcingulate cortex ( daMCC) and dorsolateral prefrontal cortex ( DLPFC)), it has been used to study cognition in healthy volunteers and to identify functional brain abnormalities in neuropsychiatric disorders, such as attention deficit hyperactivity disorder ( ADHD). During the counting Stroop, subjects report by button- press the number of words ( one to four) appearing on the screen, regardless of word meaning. Neutral- word control trials contain single semantic category common animals ( e. g., 'dog' written three times), while interference trials contain number words that are incongruent with the correct response ( e. g., 'two' written four times). The counting Stroop can be completed in approximately 20 min per subject and can be used offline ( behavioral performance) or with fMRI, positron emission tomography, event- related potentials, magnetoencephalography or intracranial recordings.
