The human action repertoire not only contains effect-producing, operant actions. Effect-precluding, prevention actions are commonplace in everyday behavior just as well. How these prevention actions are represented, however, has widely been neglected in the past. Recent proposals in the literature suggest that prevented, not occurring, events can evoke similar control mechanisms as produced action effects during action selection and execution. But there are hints that this similarity cannot be extended to action monitoring. Here we present a series of experiments investigating spontaneous anticipatory eye movements for prevented events compared to produced visual action effects. Thereby, we show reduced anticipatory eye movements for prevention actions, implying that action monitoring for prevention and operant actions indeed differs.
