Despite the ample database of research findings on the benefits of Processing Instruction (PI), research thus has primarily made use of offline measures to establish how L2 learners comprehend and process sentences. Using online methodology, such as eye-tracking, allows research to more directly measure implicit knowledge. The sensitivity of these measures requires meticulous design choices to ensure validity and replicability. This study provides an overview of the linguistic and physical design considerations necessary for creating eye-tracking materials in SLA research. The present study demonstrates the application of these design considerations in an eye-tracking study, comparing the changes in processing patterns between two types of instruction: PI and Traditional Instruction (TI) on low intermediate L2 adult learners’ acquisition of the French imperfect aspect. The results of the experimental study show beneficial gains made by L2 learners who received PI on the French imperfect tense, this was seen in both a significant increase in accuracy scores from pre-test to post-test and change in their cognitive processing as shown by eye-movement data. The present study emphasizes the need for future studies to consider methodological reflections and key design principles in eye-tracking research.

在第二语言习得研究的实验方法中使用眼动追踪：加工指令在法语不完美习得中的主要作用

尽管有大量关于加工指令 (PI) 益处的研究结果数据库，但研究因此主要利用离线测量来确定 L2 学习者如何理解和处理句子。使用在线方法，例如眼动追踪，可以让研究更直接地测量隐性知识。这些措施的敏感性需要精心的设计选择，以确保有效性和可复制性。本研究概述了在 SLA 研究中创建眼动追踪材料所需的语言和物理设计考虑因素。本研究展示了这些设计考虑在眼动追踪研究中的应用，比较了两种指令之间处理模式的变化：PI 和传统教学 (TI) 对中低二语成人学习者法语不完美方面的习得。实验研究的结果表明，在法语不完美时态上接受 PI 的 L2 学习者取得了有益的收获，这体现在从前测到后测的准确度得分显着提高以及他们的认知处理发生变化，如下所示眼球运动数据。本研究强调未来研究需要考虑眼动追踪研究中的方法学反思和关键设计原则。这体现在从前测到后测的准确性得分显着提高以及他们的认知处理发生变化，如眼球运动数据所示。本研究强调未来研究需要考虑眼动追踪研究中的方法学反思和关键设计原则。这体现在从前测到后测的准确性得分显着提高以及他们的认知处理发生变化，如眼球运动数据所示。本研究强调未来研究需要考虑眼动追踪研究中的方法学反思和关键设计原则。
