Over recent years, psychology has become increasingly concerned with reproducibility and replicability of research findings (Munafò et al., 2017). One method of ensuring that research is hypothesis driven, as opposed to data driven, is the process of …

Questionable research practices (QRPs), such as p-hacking (i.e., the inappropriate manipulation of data analysis to find statistical significance) and post hoc hypothesizing, are threats to the replicability of research findings. One key solution to …

Background Preregistration, the open science practice of specifying and registering details of a planned study prior to knowing the data, increases the transparency and reproducibility of research. Large-scale replication attempts for psychological …

Ledgerwood (1) argues that there are two independent uses of preregistration that are conflated in Nosek et al. (2) and elsewhere: “Preregistering theoretical predictions enables theory falsifiability. Preregistering analysis plans enables type I …

The preregistration of research plans and hypotheses may prevent publication bias and questionable research practices. We incorporated a modified version of the preregistration process into an undergraduate capstone research course. Students …

Preregistration involves researchers publicly registering key study elements before conducting a study to increase the transparency of research and limit the use and impact of questionable research practices. To support special education researchers’ …

BACKGROUND The ClinicalTrials.gov trial registry was expanded in 2008 to include a database for reporting summary results. We summarize the structure and contents of the results database, provide an update of relevant policies, and show how the data …

Registered Reports are a form of empirical publication in which study proposals are peer reviewed and pre-accepted before research is undertaken. By deciding which articles are published based on the question, theory and methods, Registered Reports …

Nosek et al. (1) recently joined others in advocating for “widespread adoption of preregistration” as a tool for advancing science. The language they use in making this important argument, however, creates unnecessary confusion: Like many others …

A large amount of variation exists in beliefs about the purpose and benefits of preregistration, making it difficult to implement and evaluate, and limiting its usefulness. Additionally, no single resource exists to describe what a preregistration …
