Trial procedure of the experiment. The only difference between the ME and PC block related to the agency task. In the ME block, the squares started switching color automatically and participants could stop the alternations by pressing a button. In the PC block, the agency task started with a stationary green or red square. When participants pressed a button, the squares started alternating between green and red for a random number of times. The intervals between the different tasks were jittered according to a pseudologarithmic distribution with 50% short intervals (200–2000 ms), 33.3% intermediate intervals (2600 and 4400 ms) and 16.7% long intervals (5000–6800 ms).
