Power Analysis workshop

Christopher Cox, Aarhus University

Presenter Christopher M. M. Cox (Aarhus University) leads an interactive workshop on power analysis. The workshop includes both theoretical and practical components. In the theoretical component, he discusses why to conduct power analyses, how to incorporate information from previous studies, and why we should construe power analyses as useful opportunities to think through the design dynamics of a study.

The practical component includes an R tutorial on how to conduct simulation-based power analyses for linear mixed-effects models (and possible extensions to GLMMS). To gain practical experience in how to simulate data and run power analyses, you can work through the provided tutorial using an up-to-date R version (4 or above) and RStudio (version 1.3 or above). If you do not have experience with R, you can still get a lot out of the workshop and will be able to follow along, as all code and code output are available at the link below.

Open data for developmental science

Christina Bergmann, Osnabrück University of Applied Sciences & Max Planck Institute for Psycholinguistics

Open data is one of the key mandates in calls for increased transparency, with badges, citation advantages, and sometimes even refusal to publish papers when data are not made open. For developmental researchers, this need for transparency stands in stark contrast with confidentiality, especially when working with infants. Christina reviews developmental science’s impressive history of open data to show that there are ways to ethically and responsibly share data, and then discusses different strategies and emerging best practices to balance participant protection with transparency.

Creating reproducible research reports Using RMarkdown

Michael Frank, Stanford University

In this workshop, Mike Frank (with the support of TAs Anjie Cao and Alvin Tan) led participants through the benefits of using RMarkdown to create reproducible research reports. Follow along with the exercises to see how simple it is to integrate writing and analyses in your workflow.

ManyBabies: An Introduction to Open Science

Nicolás Alessandroni & Krista Byers-Heinlein, Concordia University

In this workshop, Nicolás and Krista introduce the open science perspective for psychological research. The aim is for participants to discover, discuss, and engage in using open science practices (e.g., open access, open data, preprints, pre-registration) and to learn ways to apply them in their own research. The workshop does not require prior knowledge of open science; all those interested in learning or deepening their knowledge of how to do open research are most welcome!
