Do non-human primates have theory of mind? My new paper takes a new computational approach to this classic question. We implemented verbal theories of primates' mental representations as computational models. These models completed classic visual perspective-taking tasks.

Confidence Is Detection-Like in High-Dimensional Spaces
Abstract. Confidence estimates are often “detection-like”—driven by positive evidence in favour of a decision. This empirical observation has been interpreted as showing that human metacognition is li...

After years of analyzing thousands of drawings from hundreds of adults and children, I am excited to share my first ever paper (w/ @samiyousif.bsky.social )! Using a simple drawing task, we show how topological structure is represented in the mind and its importance in spatial memory.

A lot of experimental philosophers are people who use their philosophical expertise to make contributions to psychology. It's analogous to how there are people in math departments using their math expertise to contribute to biology and physics; noone asks if their work is 'really mathematics'.

Why do societies rely on rigid moral rules? Don't lie. Keep your promises. Don't steal. We all recognize there are good reasons to make exceptions. So why are moral rules so often categorical? Our new paper proposes an answer. 🧵

I've seen attempts to rehabilitate BF Skinner, arguing that he was unfairly maligned (most famously by Chomsky), that he was caricatured by cognitive scientists. I was surprised to hear even Josh Tenenbaum say that Skinner wasn't so bad. So I picked up "Science and Human Behavior" to see for myself.

A lot of research suggests that social cognition involves representations of Welfare-Tradeoff Ratios (WTRs), an index of how much someone values someone else. Here we find evidence for such representations in children, who make queries that are maximally informative about a partner's WTR.

A Bayesian model best explains these inferences. Participants’ judgments are best captured by a model that rationally integrates new evidence with prior expectations about others’ competence.
