Preregistration is an open science practice that requires the specification of research hypotheses and analysis plans before the data are inspected. Here, we discuss the benefits of preregistration for hypothesis-driven, confirmatory bilingualism research. Using examples from psycholinguistics and bilingualism, we illustrate how non-peer reviewed preregistrations can serve to implement a clean distinction between hypothesis testing and data exploration. This distinction helps researchers avoid casting post-hoc hypotheses and analyses as confirmatory ones. We argue that, in keeping with current best practices in the experimental sciences, preregistration, along with sharing data and code, should be an integral part of hypothesis-driven bilingualism research.

预注册对假设驱动的双语研究的好处

预注册是一种开放的科学实践，需要研究假设和分析计划的规范前检查数据。在这里，我们讨论了预注册对假设驱动的验证性双语研究的好处。使用心理语言学和双语的例子，我们说明了非同行评审的预注册如何有助于实现假设检验和数据探索之间的清晰区分。这种区别有助于研究人员避免将事后假设和分析作为验证性假设和分析。我们认为，为了与实验科学当前的最佳实践保持一致，预注册以及共享数据和代码应该是假设驱动的双语研究的一个组成部分。
