一般认为，情感图片的观看与更高水平的生理唤醒比阅读的情感词。然而，这一论断主要是基于在异质条件下对文字或图片的处理进行研究的研究。积极的，消极的，放松的，中性的，和背景（刺激片段）的文字和图片，在两个实验中，在同等的实验条件下。在实验1中，中性词引起了一个增强的晚期阳性成分（LPC），这是与区分中性背景刺激的难度增加。在实验2中，高唤起图片引起了增强的早期负性和LPC相关的促进处理这些刺激。因此，似乎在某些情况下，情感信息的处理只有在与生物学相关的刺激下才能吸引注意力。此外，这些数据可能会更好地解释这些模型的基础上，假定a。对文字和图片的情感信息的不同访问。
It is generally assumed that affective picture viewing is related to higher levels of physiological arousal than is the reading of emotional words. However, this assertion is based mainly on studies in which the processing of either words or pictures has been investigated under heterogenic conditions. Positive, negative, relaxing, neutral, and background (stimulus fragments) words and pictures were presented to subjects in two experiments under equivalent experimental conditions. In Experiment 1, neutral words elicited an enhanced late positive component (LPC) that was associated with an increased difficulty in discriminating neutral from background stimuli. In Experiment 2, high-arousing pictures elicited an enhanced early negativity and LPC that were related to a facilitated processing for these stimuli. Thus, it seems that under some circumstances, the processing of affective information captures attention only with more biologically relevant stimuli. Also, these data might be better interpreted on the basis of those models that postulate a. different access to affective information for words and pictures.
