It is. Then try using the HGF or active inference models on top of that and everyone is just like ”what?!”

I had so many of these moments since I came to Australia. We all live in our little bubbles.

Hope to cross paths again with you soon 💙

I always feel so inspired after conferences. At #ASPP2025 and #ACNS2025 I got to get to know many researchers in adjacient fields looking at similar topics and can't wait to finally model my data properly.

📢Generative Models in Neuroimaging Survey

We’re running a short survey on how neuroimaging (aka #OHBM) community defines, uses & evaluates generative models, from biophysical simulations to ML-based approaches

It was even better to share this conference experience with my exceptional honours student Kaela Afflick and my Master student Sarah Crozier who both presented posters on affect and the brain-body connection.

When philosophers meet psychologists like in the past two days at #ASPP2025 enriching conversations and new scientific friendships happen!
It was such a pleasure to be able to present first results of my constricted affect study to this great group of people. 💙

same :D, otherwise follow the boy with the curly hair and you will find me XD

Cool. I will see you there then 🙂

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.

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

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?!

I will be in Sydney on Dec 3rd, why not meet up? We seem to have common interests. Otherwise Newcastle is not far from here and has beautiful beaches :)

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

This is one of these times that I wish I had real money...

#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 😀

No idea, especially in research. I am not participating in using it and normalizing it. I support anyone using it if they do so with open eyes. I am also not perfect by any means.
My efforts wont be enough and I know I am priviledged because I have a plan B in case academia doesnt work out.

Yeah, I hope this will all crash at some point so that we can finally put quality over quantity in all aspects of society.
When I say that I don't use chatGPT a lot of people tell me that I will have to because I will be expected to get things done faster as it becomes normal. And I'm like...

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. 🙂

Premium newsletter: Based on my estimates and analysis, OpenAI needs one trillion dollars in the next four years to build 17GW of data centers and other commitments, with at least $500 billion needed for company operations. There is not enough capital to do this.

I have been so exhausted lately that I feel like I stopped parenting and just have a kid tag along... The guilt doesn't help.
