Diagrammatic set-up for intentional binding experiments. Subjects use a “Libet clock” for subjective timing. First, A, the timing of button pressing is noted (similar to Libet’s M) and, B, the timing of a randomly occurring tone. Then, C, the tone is yoked to the button press at varying intervals, and again subjects are asked to specify when the button press and tones occurred. In the setting of C, the button press subjectively occurred later and the tone occurred earlier. Hence, the two events are bound together by the intentional act.
