We focus on systems with large barrier heights where the lowest-order cumulants of the density field, that is, average position and the mean-squared displacement, show nontrivial (non-diffusive) short-time behavior characterized by the appearance of plateaus. We demonstrate that this \"cage-like\" dynamics can be well described by a discretized master equation model involving two states (related to two positions) within each potential valley.
