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 to-be-prevented events are represented, however, has widely been neglected in the past. Recent proposals in the literature suggest a distinction between the control of operant and prevention actions, i.e., that environment-related effects permeate the representation of operant actions whereas they do not play a role past initial decisions in case of prevention actions. Here we present data from movement trajectory experiments as well as findings on response durations for simple keypress responses that indicate equal influences of spatial and temporal features for to-be-produced effects and for to-be-prevented events alike. This implies that selecting and executing prevention actions relies on anticipated environmental changes.
