🚨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!!
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

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

How trait impressions of faces shape subsequent mental state inferences - Nature Human Behaviour
In this Stage 2 Registered Report, Lin et al. show that trait impressions of faces are correlated with and causally influence mental state inferences from the same faces.
