This study used a novel card-guessing task to investigate the relationship between subjective and behavioural illusory control. We compared trials in which participants (i) had no opportunity to exercise illusory control, (ii) could exercise illusory control for free, or (iii) could pay to exercise illusory control. Contingency Judgment and Intentional Binding tasks assessed explicit and implicit sense of agency, respectively. Self report data was also collected.
