The Perception Lab is committed to implementing as many open science practices as possible in our research. Below, you will find information about what this looks like for the Perception Lab, and resources to learn more about open science.

What We Do

As a lab, we create an Open Science Framework (OSF) page for each of our projects. Our OSF pages include the preregistration for each study, publicly available data and analysis code, and when possible, a copy of our experiment. We also publish preprints of our papers on PsyArXiv.

Our lab is a member of the Psychological Science Accelerator, and we regularly try to include replications of previous data into our studies.

Julia teaches a course called Psychology’s Credibility Revolution that is fully accessible to the public and addresses many issues related to open science

So you’re thinking about preregistering your research?

Preregistering is a fantastic first step to implement open science practices into your research. Preregistering means that you make all the decisions about your experiment (sample size, exclusion criteria, analyses, etc.) before you start data collection. This is supposed force researchers to think through their research before conducting it, and hopefully lower the number of Questionable Research Practices (QRPs) that can accidentally happen. If you want to read more about QRPs, there’s a great article out here!

If you want to learn more about preregistering, check out this APS article from 2016. It walks through some problems that not preregistering can lead to, how preregistering can begin to address those problems, a brief explanation about the types of preregistration, and some FAQs. The Center for Open Science (COS) also published a list of questions and answers relating to preregistration.

As mentioned above, we preregister each of our studies. Here are a few examples:
