The perceived compression of the interval between a voluntary action and a subsequent consequence is termed temporal binding and serves as an implicit measure for sense of agency. In everyday life, oftentimes multiple actions are required for goal attainment, i.e., a multi-step sequence of actions has to be performed to evoke the desired effect. However, present-day research mainly assesses the sense of agency for single actions and effects. Preliminary research on the sense of agency in longer action-event sequences is inconclusive. To fill this gap, we studied temporal binding in multi-step action-event sequences. In two experiments (free and forced choice), we employed a temporal binding paradigm in which participants had to press two keys to evoke the corresponding effects. Overall compression of the interval between actions and effects was driven by strong effect binding for both effects, while there was no significant action binding in either of the experiments.
