Reading a children's book about the brain with my son. The endsheets (<- I had to look this up) go unreasonably hard! Fun to try to figure them all out: I don't recognize the "Lungs" one. It's not obvious why these are in the book, by the way. It looks like it's just a tribute by the illustrator.

This is great advice on using AI for slide preparation. To throw in my two cents, I find that I construct most of my story while making my slides. The process of selecting graphs and crafting transitions lets me find out what works and what doesn't work.

I just returned from two back-to-back conferences. Students, I noticed that a lot of your slide decks had an oddly similar layout structure and I was able to confirm in conversations that these were AI-generated/assisted. Some thought about this for your own professional development: 🧵

Focus. Relax. Focus again. Turns out people would rather not do that! With my amazing mentors Wouter Kool and Julie Bugg, we show that people actively avoid switching between control states even in a single task, and trade off this demand against conflict. More in Wouter's thread and paper below!

🚨Paper alert!🚨 Across 5 expts, @mileritayar.bsky.social's new JEPG paper shows that people explicitly avoid switching between attention control states. Using demand selection tasks, we find that people don't just avoid cognitive conflict, but also switching between congruent and incongruent trials.

Very excited to share our first effort-learning paper in @plosbiology.org! Huge thanks to my wonderful co-authors @Jan Grohn, @thepsychologist.bsky.social and to my co-senior authors @mkflugge.bsky.social and @lilweb.bsky.social, for all their effort on this fun project. doi.org/10.1371/jour...

Proud of this team for this multidimensional tour de force! By decoding EEG signal, we show that the brain handles competing distractors through rapid dimension-specific modulation based on a multivariate conflict signal. More in @davideghez.bsky.social's 🧵.

Reactive suppression of distractor representations resolves multidimensional interference

Navigating competing attentional demands is a core cognitive function, yet how the brain tunes control in multidimensional environments remains poorly understood. Here, we used a multidimensional task-set interference paradigm in which participants attended to one of four stimulus dimensions while three others acted as distractors, combining multivariate decoding, representational similarity analysis, and encoding models applied to human EEG. Targets and distractors were initially encoded in parallel, but distractor representations were rapidly suppressed ~250 ms after stimulus onset, with suppression scaling with each distractor's own conflict history. Neither trial-to-trial adaptation nor block-level learning produced anticipatory changes in task-relevant representations. Instead, proactive control modulated the speed and efficiency of stimulus-triggered suppression. Encoding models further revealed that conflict is represented in orthogonal, dimension-specific subspaces that eventually collapse onto a shared conflict signal. These results show that multidimensional attentional control operates through selective, reactive suppression of distractor representations, guided by a structured multivariate conflict signal. ### Competing Interest Statement The authors have declared no competing interest.

New preprint! Last year we showed humans adapt attention in a dimension-specific way when multiple things compete for attention. Now we read out the neural dynamics of this adaptation. doi.org/10.1101/2025.11.16.688701 w/ @mikefreund.bsky.social @theazalabak.bsky.social @wouterkool.bsky.social
