The relative contributions of slow and fast (online) components in a modified emotional Stroop task were evaluated. The slow component, neglected in previous research, was shown to lead to the prediction of a reversed emotional intrusion effect using pseudorandomly mixed negative and neutral stimuli. This prediction was supported in Experiments 1 and 2. In Experiments 3 and 4, a new paradigm was developed that allowed a more direct observation of the nature of disruptive effects from negative stimuli. The results provided a clear demonstration of the presence of the slow component. The fast component, which has generally been assumed to be the source of the interference, was shown, in fact, to have little or no role in the disruption.
在一项改良的情绪Stroop任务中，对慢成分和快（在线）成分的相对贡献进行了评估。慢成分在先前的研究中被忽视了，研究表明，使用伪随机混合的负面和中性刺激，慢成分会导致对反向情绪干扰效应的预测。这一预测在实验1和实验2中得到了支持。在实验3和实验4中，开发了一种新的范式，该范式能够更直接地观察负面刺激的干扰效应的本质。结果清楚地证明了慢成分的存在。而通常被认为是干扰源的快成分，实际上在干扰中几乎没有作用或根本不起作用。
