In this study, two experiments were conducted to investigate the influence of global precedence on spatial Stroop effect. Combined stimuli were adopted. In Experiment 1, a Chinese character "" (up) or "" (down) was embedded in an up- or down-pointing arrow; the character was the local feature, whereas the arrow was the global feature. In the spatial task, participants were asked to identify arrow orientation, whereas in the meaning task, they were asked to respond to the character meaning. The results revealed that the RTs were longer for the incongruent trials than for the congruent trials (i.e., spatial Stroop effect) in meaning task, but not in the spatial task. In Experiment 2, an arrow was embedded in a character; the arrow was the local feature, whereas the character was the global feature. The results showed that the effect was found in the spatial task, but not in the meaning task. These results suggest that when combined stimuli are adopted, the spatial Stroop effect is modulated by global precedence. Specifically, the magnitudes of spatial Stroop effect were smaller in the global feature identification than those in the local feature identification.
在本研究中，进行了两项实验以探究整体优先性对空间斯特鲁普效应的影响。采用了组合刺激。在实验1中，一个汉字“上”或“下”被嵌入向上或向下指的箭头中；汉字是局部特征，而箭头是整体特征。在空间任务中，要求参与者识别箭头方向，而在语义任务中，要求他们对汉字的含义做出反应。结果显示，在语义任务中，不一致试验的反应时比一致试验的长（即空间斯特鲁普效应），但在空间任务中并非如此。在实验2中，一个箭头被嵌入一个汉字中；箭头是局部特征，而汉字是整体特征。结果表明，该效应在空间任务中出现，但在语义任务中未出现。这些结果表明，当采用组合刺激时，空间斯特鲁普效应受整体优先性调节。具体而言，在整体特征识别中空间斯特鲁普效应的大小比在局部特征识别中更小。
