Bonus: an R package to pre-process and extract postural indicators (e.g. average CoP, sway path length, confidence ellipses). I hope this will help with transparency.

If you work with force plates, I’d love your feedback on this! 🙏

Bottom line: Force plates are great tools! Ecological, instruction-free, and capture potentially automatic behaviors — But they’re not magic. Researchers need to be transparent about how signal is processed and stay realistic about the statistical power they can achieve.

💡Recommendations:
- Greater transparency in reporting procedures.
- Larger sample sizes
Do not base your sample size on the average postural study, our meta-analysis suggest this might not be enough. We recommend aiming to detect effect sizes consistent with other approach/avoidance measures.

Many papers miss core methods (initial posture, stimulus arousal, force-plate type, pre-processing).

Also, average sample size = 40 participants --> With this sample size, you’d be expecting an effect “detectable to the naked eye” (to paraphrase Cohen), dz ≈ 0.45!

With Dorine Vergilino-Perez, @lchaby.bsky.social, & Chrystel Besche-Richard, we meta-analysed force-plate studies on body sway while viewing (un)pleasant stimuli.

=> Weak valence effect on posture.

Bestiary of Questionable Research Practices in Psychology - Tamás Nagy, Jane Hergert, Mahmoud M. Elsherif, Lukas Wallrich, Kathleen Schmidt, Tal Waltzer, Jason W. Payne, Biljana Gjoneska, Yashvin Seet... Questionable research practices (QRPs) pose a significant threat to the quality of scientific research. However, historically, they remain ill-defined, and a co...

🧌This "bestiary" can be a vital resource for researchers, educators, and reviewers to recognize, understand, and mitigate QRPs, ultimately raising the standard of psychological research. Read the full article here: journals.sagepub.com/doi/10.1177/...

Happy Friday everyone! I just posted what I think is an important blog post on my website. It is a critique of meta-meta-analyses: meta-analyses of meta-analyses.

My editorial on how journals can earn trust.

We often use journal names as proxies for quality. This is bad bc it’s not valid. But it could be. Editors could make journal name a valid signal. And we could place value on journals that show us how they do that.
