Current models of affective processing postulate that not only valence but also the arousal dimension characterizes the emotional experience. However, up-to-date research on affective priming has mainly focused on the contributions of valence congruency to priming. In this study, the authors explored the possible influence of arousal in priming processes. For this purpose, event-related potentials and reaction times were measured in response to high- and low-arousing positive targets that were either congruent or incongruent in arousal with a prime word. Priming arousal did not influence reaction times. By contrast, the processing of high-arousing targets was facilitated by a previous exposure to a congruent prime, as reflected by the reduction in the amplitude of a late positive component around 500 ms that has been thought to reflect attentional and memory processes. These results diverge from the findings of previous studies that primed valence and suggest a differential contribution of arousal and valence to affective priming.
当前的情感加工模型假定，不仅效价而且唤醒维度也表征着情感体验。然而，最新的情感启动研究主要集中在效价一致性对启动的贡献上。在本研究中，作者探讨了唤醒在启动过程中的可能影响。为此，针对与启动词在唤醒水平上一致或不一致的高唤醒和低唤醒积极目标，测量了事件相关电位和反应时间。启动唤醒并未影响反应时间。相比之下，先前接触到一致的启动词促进了对高唤醒目标的加工，这表现为在约500毫秒处一个晚期正成分的波幅降低，该成分被认为反映了注意力和记忆过程。这些结果与先前关于启动效价的研究结果不同，并表明唤醒和效价对情感启动有不同的贡献。
