SequentialSamplingModels.jl: Simulating and Evaluating Cognitive Models of Response Times in Julia

Fernandez, K., Makowski, D., & Fisher, C.

JuliaCon Proceedings, 2025

SequentialSamplingModels.jl brings the standard evidence-accumulation models of choice and response time — the drift diffusion model and its relatives — into Julia, with one interface for simulating from them and evaluating their likelihoods.

Reality Bending Lab

Exploring the neuropsychology of reality and its distortions.

The Reality Bending Lab, led by Dominique Makowski at the University of Sussex in Brighton, UK, conducts world-leading research on reality perception, illusions, fake news, AI-beliefs, deception and its links with emotions, cognitive control and the Self. Using recording signals from the body (ECG, EDA…) and the brain (EEG), we analyse data using advanced modelling (Bayesian statistics, chaos theory, computational models) and develop open-source tools to improve neuropsychological science.

“Do not try to bend the spoon — that’s impossible. Instead, only try to realise the truth: there is no spoon. Then you'll see that it is not the spoon that bends, it is only yourself.”

Brighton is the sunniest city in the UK and, by some margin, its most cheerfully strange — on the sea, an hour from London. The University of Sussex sits just above it in the South Downs, and its School of Psychology is one of the largest and strongest in the country.

It is famous for its research on consciousness and interoception, with scientists like Anil Seth, Andy Clark, Zoltan Dienes and Hugo Critchley, its teaching of cutting-edge psychological methods (with stats rockstar Andy Field), its history of multidisciplinary research (arts and science), and its radical engagement in open and disruptive science.
