瞳孔反应已被证明是敏感的任务负荷和情绪内容。我们研究了这些因素在处理情绪效价和唤醒程度不同的单个单词时的相互作用。实验采用了两种不同认知负荷的任务，即无指导阅读和词汇判断任务，然后是突然再认任务。高唤起词的反应时间更快，附带记忆表现也比低唤起词好。与以前的研究结果相比，图片和声音，高唤起的话引起较小的瞳孔反应比低唤起的话，这些效果是独立的任务负荷，增加瞳孔直径。因此，归因于文字的情绪唤起并不强制激活自主神经系统，而是在认知水平上起作用，促进文字处理。
Pupillary responses have been shown to be sensitive to both task load and emotional content. We investigated the interplay of these factors in the processing of single words that varied in emotional valence and arousal. Two tasks of different cognitive load, uninstructed reading and a lexical decision task, were employed, followed by an unannounced recognition task. Reaction times were faster and incidental memory performance was better for high-arousing than for low-arousing words. In contrast to previous findings for pictures and sounds, high-arousing words elicited smaller pupillary responses than low-arousing words; these effects were independent of task load, which increased pupil diameter. Therefore, emotional arousal attributed to words does not mandatorily activate the autonomic nervous system, but rather works on a cognitive level, facilitating word processing.
