以往的许多行为抑制研究都采用了经典的Stroop范式和反向Stroop范式。尽管已经证实了Stroop干扰(SI)和反向Stroop干扰(RI)之间的实验性解离,但这些现象背后的机制仍不清楚。在这项研究中,我们使用功能磁共振成像(FMRI)来比较SI和RI的作用机制。我们使用四个测试:Stroop控制测试(测试1)、Stroop测试(测试2)、反向Stroop控制测试(测试3)和反向Stroop测试(测试4)来识别Stroop单词-颜色匹配任务激活的大脑区域。神经成像结果显示,SI可引起双侧额中回(BA9)的激活。而双侧额中回(BA9和BA10)、内侧额内侧回(BA8)和扣带回(BA6和BA32)在RI时表现出明显的激活。我们的结果表明,干扰类型和大脑激活之间存在分离。这些发现表明SI和RI干扰可以归因于不同的神经机制。这也表明,前额叶皮质和扣带回皮质对不同类型的干扰具有不同的敏感性,在评估患有额叶功能障碍的精神病患者的干扰控制时,反向Stroop任务可能比Stroop任务更有用。
Many previous behavioral inhibition studies have employed the classic Stroop and reverse-Stroop paradigm. Although an experimental dissociation has been demonstrated between Stroop interference (SI) and reverse-Stroop interference (RI), the mechanisms that underlie these phenomena remain unclear. In this study, we used functional magnetic resonance imaging (fMRI) to compare the functional mechanisms of SI and RI. We identified the brain regions activated by the Stroop word-color matching task using four tests: the Stroop control test (Test 1), Stroop test (Test 2), reverse-Stroop control test (Test 3), and reverse-Stroop test (Test 4). Neuroimaging results revealed that SI elicited activation in the bilateral middle frontal gyrus (BA9). In contrast, a number of other regions, including the bilateral middle frontal gyrus (BA 9 and BA10), medial frontal gyrus (BA 8), and cingulate gyrus (BA6 and BA 32) exhibited significant activation during RI. Our results indicate that there is a dissociation between the types of interference and brain activation. These findings suggest that SI and RI interference can be attributable to different neural mechanisms. It also suggests that the prefrontal cortex and the cingulate cortex are differentially sensitive to various types of interference, and that the reverse-Stroop task may be more useful than the Stroop task for evaluating interference control in psychiatric patients with frontal dysfunction.
