The benefits of preregistration for hypothesis-driven bilingualism research

Daniela Mertzen, Sol Lago and Shravan Vasishth

Preregistration is an open science practice that requires the specification of research hypoth- eses and analysis plans before the data are inspected. Here, we discuss the benefits of preregis- tration 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 con- firmatory 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.
