Figure 1.

Rational decision-making in inhibitory control. The figure abstracts out ideas common across recent decision-making models for inhibitory control into a single framework. Left: an example where task-relevant events e1 and e2 are mutually exclusive (e.g., a forced choice stimulus), and e3 occurs at some later point in time. Sensory evidence from these events are gradually reconciled with prior expectations to form a noisy, evolving belief, or subjective probability, about whether the event occurred. These beliefs form the basis of an ongoing valuation of, and selection between, available actions. Right: A representation of this sequential decision-making process. At each time point, noisy sensory inputs (x_i) are incorporated into beliefs (b_i), which are transformed into a choice between actions (a1,… an, wait) based on the decision policy (∏).
