About Arthur Prat-Carrabin
Soon on the job market!
I'm interested in how information is represented in the brain, from encoding-decoding models of perception to human inference under uncertainty. In my work, theory always informs experiments, and vice versa.
I am proud of this theoretical paper, presented at NeurIPS: it gives analytical approximations to the bias and the variance of the Bayesian mean. A related, experimental work on number perception is reported in this article, published in Nature Human Behaviour.
This Psychological Review paper looks at human inference in changing environments (change points), but with temporal structure in the signal. Finally, this work is a detailed investigation of human responses in a probabilistic inference task – and the results constitute quite a challenge to the Bayesian paradigm.
Feel free to reach out to talk about all these things!
