Previous experience of action-effect predictability and delay affect perceived agency and decision-making independently

The possible cognitive effect of sense of agency (SoA) has attracted increasing attention. Previous findings suggest that SoA has an effect on action control, time perception, and memory. Here we investigated whether SoA can also influence decision-making. We conducted two experiments, in which we induced high or low predictability by manipulating the contingency between keypresses (action) and ball movements (effect), before assessing SoA and risk-taking (in Experiment 1); and induced both predictability and short or long time delay of action-effect, before assessing SoA, risk-taking, and intertemporal decision-making (in Experiment 2). Higher predictability increased SoA and promoted risk-taking, but did not impact intertemporal decision-making; Shorter delay increased SoA and promoted Larger-Later options, but did not impact risk-taking decision-making. While our findings suggest that some decision-making processes are affected by the same factors as SoA is, we did not find any evidence for any direct impact of SoA on decision-making.
