🚨New preprint with my stellar student Junsong

A Small-World Mind Theory of social cognition doi.org/10.31234/osf...

Big network, close connection🤯

It explains why low-dimensional findings dominate & high-dimensional evidence emerges

Naturalistic designs matter to understanding the complex mind

First paper from my lab out @commspsychol.nature.com

www.nature.com/articles/s44271-025-00275-w

Latent factor models are popular for mental representation of people, e.g. warmth & competence

But we show in naturalistic contexts, more complex representations are needed: high-dimensional networks

Check out our new work with @xallysie.bsky.social, @erichehman.bsky.social, and my student Ruoying on a tutorial for Representational Similarity Analysis! Thanks for the fun collaboration!!

Eric Hehman @erichehman.bsky.social · Jul 7

We had a new tutorial on representational similarity analysis come out recently. Led by @xallysie.bsky.social with Ruoying Zheng and @chujunlin.bsky.social

This technique lets you compare patterns across diff types of measures (eg correlate correlation matrices), super flexible

Check out our new TiCS paper! Thanks @freemanjb.bsky.social for the fun collaboration!!

Investigating social impressions in a high-dimensional space could provide valuable insights beyond the compressed dimensions!

Jon Freeman @freemanjb.bsky.social · Jun 18

In a TiCS paper, @chujunlin.bsky.social & I propose a high-dimensional model of social impressions.

Existing models focus on 2–4 latent dimensions (e.g. trustworthy/warm), but they often fall apart across different contexts, cultures, & perceivers. We need a paradigm shift.

A high-dimensional model of social impressions

People form social impressions from visual cues such as faces, which are argued by various models to arise from some limited set of fixed dimensions (e.g., trustworthiness and dominance). We argue tha...
