Research on literacy has become universal and is essential for researchers of various disciplines, educators, and psychologists. For this article, we examined the most important methodological challenges that arise when conducting literacy research across languages, some of which have long been acknowledged in the relevant literature. Specifically, we focused on challenges related to research on word reading, spelling, passage comprehension, and writing, ranging from the target skills, constructs, and assessment issues to the matching of the samples and measurement and factorial invariance issues. We conclude that although theoretical and applied issues have been addressed in the literature, to date, this has happened only with limited relevance for reading and writing research across languages. The discussion provides some relevant evidence from a neuroscience perspective to promote useful insights and greater methodological rigor in literacy research across languages.

跨语言识字研究的方法论问题：来自字母拼写法的证据

扫盲研究已变得普遍，对各个学科的研究人员、教育工作者和心理学家来说都是必不可少的。在本文中，我们研究了在进行跨语言扫盲研究时出现的最重要的方法论挑战，其中一些早已在相关文献中得到承认。具体而言，我们专注于与单词阅读、拼写、段落理解和写作研究相关的挑战，从目标技能、结构和评估问题到样本匹配和测量以及因子不变性问题。我们得出的结论是，尽管文献中已经解决了理论和应用问题，但迄今为止，这仅与跨语言阅读和写作研究的相关性有限。
