Drift and diffusion increase with memory load. Experiment 1a maximum likelihood parameter fits for the diffusion (a, b) and drift (c, d) scaling parameters during memory and encoding. Color intensity reflects normalized proportion of bootstrap iterations. As detailed in the Methods, all parameters are rates (change per second); dynamics during encoding evolve over a fixed period of time (simulated as 1 s), while memory dynamics evolve over the memory delay, which varied from trial to trial. *p < 0.05, **p < 0.01, ***p < 0.001, bootstrap.
