Performance-gated deliberation: A context-adapted strategy in which urgency is opportunity cost

Fig 2

Non-stationary opportunity cost.

(A) Top: Dynamics of trial performance (; blue) with its distribution as well as dynamics of between context-conditioned averages of performance (; orange), and the effectively stationary average performance (; purple). Bottom: these are decomposed into a hierarchy by filtering reward history on trial, context, and long timescales, respectively. (B) Two hypothetical forms for context-specific trial opportunity cost. Top: Trial-unaware cost in which context varies the slope around ρ. Bottom: Trial-aware cost in which context variation is through a bias (c.f. Eq 5).
