In the present work we analyzed the pupil size behavior of 40 subjects while they read well-defined sentences with different contextual predictability (i.e., regular sentences and proverbs). In general, pupil size increased when reading regular sentences, but when readers realized that they were reading proverbs their pupils strongly increase until finishing proverbs' reading. Our results suggest that an increased pupil size is not limited to cognitive load (i.e., relative difficulty in processing) because when participants accurately recognized words during reading proverbs, theirs pupil size increased too. Our results show that pupil size dynamics may be a reliable measure to investigate the cognitive processes involved in sentence processing and memory functioning.
在本研究中，我们分析了40名受试者在阅读具有不同语境可预测性的明确句子（即常规句子和谚语）时的瞳孔大小行为。一般来说，阅读常规句子时瞳孔大小会增加，但当读者意识到自己在阅读谚语时，他们的瞳孔会大幅增大，直到读完谚语。我们的结果表明，瞳孔大小增加并不局限于认知负荷（即处理过程中的相对难度），因为当参与者在阅读谚语时准确识别单词时，他们的瞳孔大小也会增加。我们的结果表明，瞳孔大小动态可能是研究句子处理和记忆功能中涉及的认知过程的可靠指标。
