When reading a line like "the glow of the flame briefly illuminated his face", most readers tend to build an image in their mind. 🧠

Representational Momentum Transcends Motion Dillon Plunkett & Jorge Morales (2025) Psychological Science

When we see something that's moving, our memories about it end up projected forward in time: We remember it further along than it was. In a new paper in 𝘗𝘴𝘺𝘤𝘩𝘰𝘭𝘰𝘨𝘪𝘤𝘢𝘭 𝘚𝘤𝘪𝘦𝘯𝘤𝘦, out today and led by @dillonplunkett.bsky.social, we demonstrate that this happens even when there is 𝙣𝙤 𝙢𝙤𝙩𝙞𝙤𝙣 𝙬𝙝𝙖𝙩𝙨𝙤𝙚𝙫𝙚𝙧.🧵

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🧠📈

Biological markers and psychosocial factors predict chronic pain conditions - Nature Human Behaviour Fillingim et al. show that biological and psychosocial factors jointly predict conditions associated with chronic pain.

We show that combining biological 🧬 and psychosocial 📋 data offers a much stronger, more reliable path to predicting pain and diagnosis. 🧵

Make science more collegial: why the time for ‘adversarial collaboration’ has come Bringing together proponents of rival theories to test their ideas against each other can advance science — but only if all sides can accept that they might be wrong.

"... supporters of GNWT called IIT a pseudoscience. Such language has no place in a process designed to establish working relationships between competing groups"

Sex differences in prenatal development of neural complexity in the human brain - Nature Mental Health A magnetoencephalography study provides evidence that neural signal complexity declines with brain maturation in human fetuses and newborns and the decline occurs faster in male fetuses.

Fetuses have the right signatures according to IIT for consciousness, especially if they're premature and male (apparently): www.nature.com/articles/s44...

There are consequences of IIT in the real world. For real people. It clearly already has the juice to be a practical concern.

i used to have blog on consciousness. i just uploaded my final post there, in which i responded to Alex Gomez-Marin & Anil Seth's recent commentary on the scientific status of IIT.

Emergent Symbolic Mechanisms Support Abstract Reasoning in Large Language Models Many recent studies have found evidence for emergent reasoning capabilities in large language models, but debate persists concerning the robustness of these capabilities, and the extent to which they ...

LLMs have shown impressive performance in some reasoning tasks, but what internal mechanisms do they use to solve these tasks? In a new preprint, we find evidence that abstract reasoning in LLMs depends on an emergent form of symbol processing arxiv.org/abs/2502.20332 (1/N)

General ML question: If a high-dimensional model predicts the training set 100%, but generalizes to held-out data to a realistic degree (e.g. an r2 of 0.1-0.2), is it overfit? Or is it only overfitting if it fails to generalize?
