There are two alternative explanations of the Stroop phenomenon. Several studies have revealed that the difference in performance on congruent and incongruent trials can arise from response interference. On the contrary, many authors have claimed that Stroop interference might occur at earlier processing stages related to semantic or conceptual encoding. The present study aims to determine the number and nature of the factors necessary to account for the multiple components of Stroop interference.
The sample consisted of 247 undergraduate and postgraduate students. We employed the computerized version of the Stroop task adapted to the Iranian population. An exploratory principal components analysis was conducted on the correlations of 6 variables (reaction time under congruent and incongruent conditions, omission error under congruent and incongruent conditions, and commission error under congruent and incongruent conditions).
Two factors were extracted. The first factor may be semantic interference, and the second factor may be response interference.
The findings of this research are consistent with the multiple-stage account, claiming that Stroop interference is because of both semantic and response interferences.
对于斯特鲁普现象有两种不同的解释。多项研究表明，在一致和不一致试验中表现的差异可能源于反应干扰。相反，许多作者声称，斯特鲁普干扰可能发生在与语义或概念编码相关的早期加工阶段。本研究旨在确定解释斯特鲁普干扰多个组成部分所需因素的数量和性质。
样本包括247名本科生和研究生。我们采用了适用于伊朗人群的计算机化斯特鲁普任务版本。对6个变量（一致和不一致条件下的反应时间、一致和不一致条件下的遗漏错误以及一致和不一致条件下的误判错误）的相关性进行了探索性主成分分析。
提取出两个因素。第一个因素可能是语义干扰，第二个因素可能是反应干扰。
本研究结果与多阶段解释一致，即斯特鲁普干扰是语义和反应干扰共同作用的结果。
