Two paths to bias! We used neurally-informed drift diffusion models to pull apart explicit vs. implicit perceptual bias and found that pre-stimulus beta power mediates how the last choice biases the next, but only in stable probability environments, now published: 🔗 link.springer.com/article/10.1...
Two Paths to Bias: Distinct Influences of Stimulus Probability and Previous Choice on Drift Diffusion Parameters - Computational Brain & Behavior
Perceptual decisions are shaped by prior information and choice history, yet their distinct computational implementations remain unclear. Here, we jointly model these sources of bias using hierarchica...
