一般来说，人们说出带有感情色彩的词的颜色要比说出没有感情色彩的词的颜色慢。然而，对这种情绪Stroop效应的分析（Larsen, Mercer, & Balota, 2006）表明，与情绪中性词相比，使用的充满情绪的词有时更长，频率更低，正字法邻域更小。单词特征的这种差异提出了一种可能性，即情感斯特鲁普效应部分是由词汇而不是刺激的情感方面引起的——一项发现支持了这一结论，即命名低频单词的颜色的反应时间比命名高频单词的反应时间长（伯特，2002）。为了检验价和频率在颜色命名中的相对贡献，我们让64名参与者完成了一个实验，在这个实验中，每个变量都在3 × 2的析因设计中被操纵；长度、正交邻域密度和觉醒是平衡的。结果表明，效价和词频在情感斯特鲁普效应中起着相互作用。
People are generally slower to name the color of emotion-laden words than they are to name that of emotionally neutral words. However, an analysis of this emotional Stroop effect (Larsen, Mercer, & Balota, 2006) indicates that the emotion-laden words used are sometimes longer, have lower frequencies, and have smaller orthographic neighborhoods than the emotionally neutral words. This difference in word characteristics raises the possibility that the emotional Stroop effect is partly caused by lexical rather than by emotional aspects of the stimuli-a conclusion supported by the finding that reaction times to name the color of low-frequency words are longer than those for high-frequency words (Burt, 2002). To examine the relative contributions of valence and frequency in color naming, we had 64 participants complete an experiment in which each of these variables was manipulated in a 3 X 2 factorial design; length, orthographic neighborhood density, and arousal were balanced. The data indicate that valence and word frequency interact in contributing to the emotional Stroop effect.
