Abstract：
Pupil dilation has been associated with the effort required to perform various cognitive tasks. At the lexical level, some studies suggest that this neurophysiological measure would provide objective, real-time information during word processing and lexical access. However, due to the scarcity and incipient advancement of this line of research, its applicability, use, and sensitivity are not entirely clear. This scoping review aims to determine the applicability and usefulness of pupillometry in the study of lexical access by providing an up-to-date overview of research in this area. Following the PRISMA protocol, 16 articles were included in this review. The results show that pupillometry is a highly applicable, useful, and sensitive method for assessing lexical skills of word recognition, word retrieval, and semantic activation. Moreover, it easily fits into traditional research paradigms and methods in the field. Because it is a non-invasive, objective, and automated procedure, it can be applied to any population or age group. However, the emerging development of this specific area of research and the methodological diversity observed in the included studies do not yet allow for definitive conclusions in this area, which in turn does not allow for meta-analyses or fully conclusive statements about what the pupil response actually reflects when processing words. Standardized pupillary recording and analysis methods need to be defined to generate more accurate, replicable research designs with more reliable results to strengthen this line of research.
摘要：
瞳孔扩张与执行各种认知任务所需的努力有关。在词汇层面，一些研究表明，这种神经生理学措施将提供客观的，在文字处理和词汇访问过程中的实时信息。然而,由于这一研究领域的稀缺和起步，其适用性，使用,敏感性并不完全清楚。本范围审查旨在通过提供该领域研究的最新概述，确定瞳孔测量法在词汇访问研究中的适用性和实用性。按照PRISMA协议,这篇综述包括16篇文章。结果表明,有用的,和评估单词识别的词汇技能的敏感方法，单词检索,和语义激活。此外，它很容易适应该领域的传统研究范式和方法。因为它是非侵入性的，目标,和自动化程序，它可以适用于任何人口或年龄组。然而,这一特定研究领域的新兴发展和纳入研究中观察到的方法多样性尚不允许在这一领域得出明确的结论，这反过来又不允许荟萃分析或关于处理单词时瞳孔反应实际反映的完全结论性陈述。需要定义标准化的瞳孔记录和分析方法，以生成更准确的，具有更可靠结果的可复制研究设计，以加强这一研究路线。
