The US president repeatedly advised people, “Don't take Tylenol,” but scientists say that strong evidence between the medication and autism is lacking.

A new study published in Psychological Science, by @sandrajgeiger.bsky.social from @acee.princeton.edu, highlights how people around the world often overestimate climate skepticism and presents ways to push back on this misperception. #ClimateChange

The beautiful Hall of Mirrors that today hosts an exciting symposium on “The underconceptualization of everyday life”, put together by @ericman.bsky.social 🤩
with @bpomie.bsky.social @benedek.bsky.social and myself at the ESPP conference in Warsaw. So much to think about !

Today at #ECVP25 @mmellon.bsky.social presented new data of an #fNIRS study providing the first evidence of selectivity for social interaction events in visual cortex in 6- and 10-month-old babies 👶🏻
Tempting to think that this reveals where social perception begins in the brain 🧠

At the #ECVP2025 today Violette Munin presented her new fMRI work on the visual stream for processing social information.
If you are around and want to continue the discussion, we are here for this ☺️
Stay tuned for more talk from our lab in the upcoming days!

Excited to share that I’ll be joining Dr. Liuba Papeo’s lab (@ljubapi.bsky.social) at CNRS Institute of Cognitive Sciences in France (@isc-mj.bsky.social) as a postdoc this fall! Grateful to be supported by the Fyssen Foundation (@fondationfyssen.bsky.social ) -- looking forward to this new chapter!

• Seeing two bodies face-to-face is sufficient to trigger the social interaction network, with effects that are strongly left lateralized (see also www.cell.com/current-biol... )
Converging evidence that left extrastriate body area supports visual sensitivity to social interactions
Gandolfo et al. use a combination of correlational (fMRI) and causal (TMS) methods to show that activity in the left extrastriate body area (lEBA) is required to efficiently perceive face-to-face huma...

Two key findings:
• Key regions of the social-interaction network (pSTS, EVA and MT) show selectivity to social interaction also when depicted in static images. Thus, motion is not necessary to trigger the social interaction network

🚨 new paper out!
Perception of motion and of social interactions are two processes that happen to be localized around the same brain anatomy: lateral occipitotemporal areas. Is motion necessary to see social interactions network?

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.
Experimentology cover: title and curves for distributions.

The decision means that the US biomedical agency has to restore funding to hundreds of research projects, but the government will likely appeal.

The paper includes an internal replication of the effects and a set of interesting analysis in the supplementary material, which nicely support the conclusions of the study.

Two main observations:
1. A striking parallel between object and relation categorization suggests that relations between objects are extracted as rapidly as categorical object information;
2. Representations of objects and relations are the building blocks of scene recognition

We found that it takes no longer to access the category of objects (people vs other) in a scene, than to access the relation between them (facing vs non-facing), while recognizing their (inter)action (fight or dance) takes significantly longer.

We presented scenes showing two people (or two objects). We designed a behavioral paradigm to compare how much it takes to recognize that:
• There are people (vs other objects)
• They are facing vs facing away from each other
• They are dancing vs fighting

You wouldn’t drink from a glass if a fish is IN the glass, or would not grab a chair if one is already sitting ON it.
How do we represent relations between things? And how does it relate to object and action recognition?
