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...

In our latest collection of #free #education #resources, we explore #cognitive #science with Professor Ralf Haefner from the @haefnerlab at @UofR . How do processes in our #brains #bias our #decision-making? futurumcareers.com/how-do-br…

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

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...

Excited to finally share this paper! A superb collaboration with @sabyashiv1729 @haefnerlab and @AngelakiLab! Aberrant causal inference and presence of a compensatory mechanism in autism spectrum disorder doi.org/10.7554/eLife.71866

Aberrant causal inference and presence of a compensatory mechanism in autism spectrum disorder

Individuals within the autism spectrum disorder implicitly outweigh integration (rather than segregating) when performing causal inference and have developed an explicit compensatory mechanism as...

Replying to @haefnerlab @wrongu @ankani @jake
7/n Our data are not explainable by existing alternative accounts: neither integration-to-bound nor attractor-dynamics within a decision area are sensitive to the balance of sensory and category information - only to their combination.
