How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

Transitions in dynamical regime and neural mode during perceptual decisions - Nature

Simultaneous recordings were made of hundreds of neurons in the rat frontal cortex and striatum, showing that decision commitment involves a rapid, coordinated transition in dynamical regime and neura...

Happy to share a new preprint in which @paulbuerkner.com and I introduce a novel model-based approach for precisely estimating the onset and offset of M/EEG effects!

The idea behind this measure is that voluntary action requires an effort that involuntary action does not.

Thanks to Elisabeth Pacherie, @emiliecaspar.bsky.social , @axc.bsky.social , Uri Maoz for their help to this work. 4/4

Moreover, we introduce another measure of volition that aligns with the measures mentioned above: the effort exerted in reporting the decisions. More specifically, participants selected their answers using handgrips that measured the effort exerted. 3/N

Our study indicates that self-reported volition, the Readiness Potential, and the Temporal Binding increase when making decisions that could increase our remuneration compared to decisions that did not. This was not observed when contrasting decisions that involved more or less deliberation. 2/N

we investigated how adding consequence to one's decision, and increasing the degree of deliberation, impacted different markers of voluntary action. /N

No confidence, only opinion « I found » « I see » I just wanted to help with my understanding of it not as an expert but as someone interested in these questions :) I think that if you want to help people understanding your claims it’s valuable to have input of what are the peoples understanding

Guillaume Pech @guillaumepech.bsky.social · Aug 4

I will be (maybe wronngly) more confident if it’s just M differences rather than S differences 2/2

Guillaume Pech @guillaumepech.bsky.social · Aug 4

If there is 5 studies, 1 finding a significant effect, 4 that doesn’t, I have the impression that it give extra information to know the magnitude of the effects and their sign in order to evaluate if it is worth trying to pursue this line of research. 1/2

Guillaume Pech @guillaumepech.bsky.social · Aug 4

Ok, I thought that type S and M were from a bayesian framework, which do not adress the uncertainty about long run sampling, but rather the uncertainty of observed data in combination with prior beliefs.

Guillaume Pech @guillaumepech.bsky.social · Aug 4

For the S error, I just see that as a different philosophy, not thinking about the long run sampling. I found sometimes type I & II error confusing as we never conduct the same study in psychology.

Guillaume Pech @guillaumepech.bsky.social · Aug 4

I found the M error pretty convincing. For instance a study claiming 20% effect of a treatment but other studies replicating 5% effects might be considered as a failed replication even though all significant, because the first did a M error.

What is the most compelling book providing an overview of the successes and worthwhile contributions that psychology has made over the last century? Has it even been written? As just one example, in my Human Factors course I would discuss the 3rd break light. stanley-r-harris.co.uk/blog/why-do-...

Why do cars have a 3rd brake light

When you hit the brakes, the car’s brakes will flash to warn following drivers that you’re slowing or stopping. Without brake lights, our roads would be chaotic and deadly.

NEW: Statement from the PCI RR Managing Board on the withdrawal of Infant and Child Development as a PCI RR-friendly journal, and the decision by Wiley to refuse preprints that have been peer-reviewed by @peercommunityin.bsky.social / @pci-regreports.bsky.social

Read here ➡️ osf.io/tn8mh

In 2024, Infant and Child Development (ICD) withdrew as a PCI RR-friendly journal and reneged on three Stage 1 recommendations issued by PCI RR. In addition, Wiley – the publisher of ICD – notified PCI RR and the PCI core team of its decision to withdraw all Wiley journals from PCI and PCI RR, including an additional 9 PCI-friendly journals. Finally, Wiley appears to have banned all of its ~1600 journals from considering submissions that have been previously reviewed by PCI or PCI RR. This statement explains the history of ICD joining PCI RR and developments that led to the current outcome. The PCI RR Managing Board believes that this shift in policy to become “PCI-hostile” renders Wiley journals incompatible not only with community-based preprint review but with preprint archiving in general.
