Actions are typically accompanied by sensory feedback (or action‑effects). Action‑effects, in turn, influence the action. Theoretical accounts of action control assume a pre‑activation of action‑effects prior to the action execution. However, direct evidence for the pre‑activation is scarce. The current study includes three behavior experiments and one EEG experiment. In behavior experiments, a clock with a fast‑rotating clock hand was presented while the participants made a voluntary keypress. The task was to report the keypress time by giving the clock hand position when the keypress was made. In the EEG experiment, participants made a keypress when the clock hand was right at the 12 o’clock position while watching two flickering stimuli. Results indicate that in the presence of a predictable action‑effect (i.e. a 250‑ms delayed sound), the distribution of visuospatial attention around the clock was shifted towards the clock hand position of action‑effect onset, thus demonstrating an influence of action‑effects on an action‑related task. No attention shift was observed after action execution, however. Importantly, we could show that the attention shift caused by the action‑effect occurred already at about 1 second before the action execution, which was further preceded and predicted by a lateralisation of alpha oscillations in the parieto‑occipital area from about 1.8 seconds before the action execution. Therefore, our results indicate a very early pre‑activation of action‑effect during a voluntary action. The neural implementation of the action‑effect pre‑activation was achieved through alpha lateralisation, as the spatial location was the key feature of action‑effects in the current study.
