Researchers debate whether Stroop interference from an incongruent word in color-naming response time is caused by response competition or by response exclusion. According to the former account, the interference reflects competition in lexical response selection during color name planning, whereas according to the latter, the interference reflects the removal of a motor program for the incongruent word from an articulatory buffer after planning. Here, numerical predictions about the magnitude of Stroop interference as a function of stimulus onset asynchrony were derived from these accounts. These predictions were then tested on representative data in the literature. Measures of goodness-of-fit showed that the numerical predictions of a response competition account are closer to the empirical data than those of the response exclusion account. These results indicate that response competition provides a better explanation of interference in naming than does response exclusion.
研究人员就不一致字词在颜色命名反应时的斯特鲁普干扰是由反应竞争还是由反应排除引起存在争议。根据前者的解释，这种干扰反映了在颜色命名计划过程中词汇反应选择的竞争，而根据后者的解释，这种干扰反映了在计划之后从发音缓冲区中排除了不和谐词的运动程序。在此，根据这些解释推导出了刺激起始时间间隔作为斯特鲁普干扰幅度的函数的数值预测。然后，将这些预测应用于文献中的代表性数据进行测试。拟合度的衡量标准表明，反应竞争解释比反应排除解释更能准确预测干扰命名的数值预测。这些结果表明，反应竞争比反应排除更能解释命名中的干扰。
