1/n Our work on a perceptual confirmation bias is finally out. Why do different perceptual decision-making studies find different temporal biases? What is their computational basis? Joint work with @wrongu, @ankani, @jake and Jeff Beck.. journals.plos.org/ploscompbi…

A confirmation bias in perceptual decision-making due to hierarchical approximate inference

Author summary When humans and animals accumulate evidence over time, they are often biased. Identifying the mechanisms underlying these biases can lead to new insights into principles of neural...

Next week (Nov 16), @SussilloDavid will tell his unofficial story. Among all that we have heard over the years, his is particularly poignant and harrowing. Join us on Zoom. Get the link through growingupinscience.org. #phdchat #phdlife #AcademicTwitter

We believe 💎 Everyone should be able to read and publish research for free 🌍 Research publishing should be commonly owned and run, not for profit 🔢 All data should be open and re-usable We are delighted to announce a new open publishing initiative nmop.io

Inferring sources of suboptimality in perceptual decision making using a causal inference task

Perceptual decision-making has been extensively modeled using the ideal observer framework. However, a range of deviations from optimality demand an extension of this framework to characterize the...
