🚨New Preprint🚨
from amazing PhD student @ryguy.io!
We augmented the classic DDM to account for state-dependent changes in decision strategy and found a clear improvement. Applied to a novel 24 hour dataset we found support for circadian influence on decisions and more! Check out thread and paper!

Move over, GLM-HMM—there’s a new hidden Markov model in town.
In our new preprint, we introduce the DDM-HMM: a model that jointly infers latent decision states from reaction times and choices.
Using 24-hour behavioral data from rats, we found that evidence accumulation changes with time of day!
