Action control theories propose that forming a new action plan involves integrating task-relevant percepts and motor programs into an event file, resulting in the binding of all components associated with a specific action episode. While repeating all elements of an event file in a subsequent action episode enhances execution speed and reduces errors, partial repetitions lead to performance detriments. Notably, the observed binding effects in action control tasks are typically short-lived, mainly attributed to event file decay. In multiple experiments, another important factor contributing to the transient nature of binding effects is explored: Interference - caused by alternating associations of a single stimulus with different responses or a single response with different stimuli over the course of the experiment. Previous studies could show that paradigms that mitigate interference by expanding the stimulus set can produce stronger and more enduring stimulus-response associations, even with a single pairing (e.g., in long-lag repetition priming). However, due to a limited response set, these paradigms do not prevent a single reaction being bound to different stimuli. In a series of experiments, we systematically explored the influence of multiple bindings of a single distractor or response on overall binding effects. To this end, we manipulated whether distractors and/or responses could occur in several trials during an experiment or only in a single trial.
