Our paper on improving statistical reporting in psychology is now online 🎉

As a part of this paper, we also created the Transparent Statistical Reporting in Psychology checklist, which researchers can use to improve their statistical reporting practices

www.nature.com/articles/s44...
Transparent and comprehensive statistical reporting is critical for ensuring the credibility, reproducibility, and interpretability of psychological research. This paper offers a structured set of guidelines for reporting statistical analyses in quantitative psychology, emphasizing clarity at both the planning and results stages. Drawing on established recommendations and emerging best practices, we outline key decisions related to hypothesis formulation, sample size justification, preregistration, outlier and missing data handling, statistical model specification, and the interpretation of inferential outcomes. We address considerations across frequentist and Bayesian frameworks and fixed as well as sequential research designs, including guidance on effect size reporting, equivalence testing, and the appropriate treatment of null results. To facilitate implementation of these recommendations, we provide the Transparent Statistical Reporting in Psychology (TSRP) Checklist that researchers can use to systematically evaluate and improve their statistical reporting practices (https://osf.io/t2zpq/). In addition, we provide a curated list of freely available tools, packages, and functions that researchers can use to implement transparent reporting practices in their own analyses to bridge the gap between theory and practice. To illustrate the practical application of these principles, we provide a side-by-side comparison of insufficient versus best-practice reporting using a hypothetical cognitive psychology study. By adopting transparent reporting standards, researchers can improve the robustness of individual studies and facilitate cumulative scientific progress through more reliable meta-analyses and research syntheses.

was wondering why my model takes 130! hours to invert, found out that the julia extension on vscode has a prespecified number of chains it can use specified in its settings json file... Guess the number?!

Neat that my review of Zhang et al.'s "Cortical and subcortical mapping of the human allostatic–interoceptive system using 7 Tesla fMRI" was quoted in this Research Briefing. It was one of my favorite papers I reviewed in 2024! rdcu.be/eOlTT by Jiahe Zhang, @lisafeldmanbarrett.com and others

#HurricaneMelissa brought destruction to Jamaica and especially Westmoreland where I have family. The planet isn't happy with us and Islanders especially have to suffer.
We haven't heard from our family yet but will do our best to help rebuild the community. Please everyone #helpJamaica

Who is planning to go to the @ohbmofficial.bsky.social Australia chapter meeting? I'm leaving Australia soon so want to meet as many lovely Aussies as possible on my conference tour 😀

I fear the wide-spread adoption of generative AI tools will work against us all finally slowing down and degrowing. Instead people will be expected to be inhumanely "productive" since it is now possible with these tools.

does someone good at coding & analysis want to work remotely w/ us in the coming few months (before end of 2025), as a paid consultant? project will be on neurofeedback (fMRI, ECoG, calcium imaging). we'll work towards developing the experiments & analysis pipelines together. if so pls DM me ur CV🧠📈

We’re looking for a postdoc to join our Max Planck group in Germany some time in 2026. If you have computational and/or neuroimaging expertise, and are interested in questions intersecting perception and cognition, please reach out! I’ll also be happy to chat at the #Bernsteinconference this week.

It was a great pleasure presenting preliminary results from my ongoing study on social-affective inference and constricted affect at the @newybrains.bsky.social lunch symposium series.
We found some interesting first effects of positive affective surprise and bodily responses. 🙂

The only thing ChatGPT ever does.
Andrew Kadel @DrewKadel@social.coop My daughter, who's had a degree in computer science for 25 years, posted this about ChatGPT on Facebook. It's the best description I've seen. Something that seems fundamental to me about ChatGPT, which gets lost over and over again: When you enter text into it, you're asking "What would a response to this sound like?" If you put in a scientific question, and it comes back with a response citing a non-existent paper with a plausible title, using a real journal name and an author name who's written things related to your question, it's not being tricky or telling lies or doing anything at all surprising! This is what a response to that question would sound like! It did the thing! But people keep wanting the "say something that sounds like an answer" machine to be doing something else, and believing it *is* doing something else. It's good at generating things that sound like responses to being told it was wrong, so people think that it's engaging in introspection or looking up more information or something, but it's not, it's only, ever, saying something that sounds like the next bit of the conversation.

While masked agents were violently attacking a delivery worker this morning, bystanders repeatedly asked to see their badge numbers but they refused.

Bystander: You guys are ruining this country, you know that, right?

Agent: Liberals already ruined it.
