Abstract Voluntary actions and causally linked sensory stimuli are perceived to be shifted towards each other in time. This so-called temporal binding is commonly assessed in paradigms using the Libet Clock. In such experiments, participants have to estimate the timing of actions performed or ensuing sensory stimuli (usually tones) by means of a rotating clock hand presented on a screen. The aforementioned task setup is however ill-suited for many conceivable setups, especially when they involve visual effects. To address this shortcoming, the line of research presented here establishes an alternative measure for temporal binding by using a sequence of timed sounds. This method uses an auditory timer, a sequence of letters presented during task execution, which serve as anchors for temporal judgments. In four experiments, we manipulated four design factors of this auditory timer, namely interval length, interval filling, sequence predictability, and sequence length, to determine the most effective and economic method for measuring temporal binding with an auditory timer.

Introduction Opening an app on an outdated smartphone typically comes with a slight and sometimes barely noticeable time interval between tapping the screen and opening of the app. However, the perceived time interval between tap and the presentation of the app’s content is shortened. More precisely, when the tap opens the app, the tap is judged to occur later, and the app is judged to flash earlier, as compared to situations where there is only a tap or only a flashing of an app. This socalled temporal binding phenomenon (also referred to as intentional binding) is widely employed in research on voluntary actions and their subsequent effects (Haggard, Clark, & Kalogeras, 2002; Moore & Obhi, 2012). It describes the finding that an action and a causally linked sensory event are perceptually shifted towards each other in time, as compared to either of the events happening in isolation. That is, if you tapped on the icon on your smartphone but the app did not open, you would have a more accurate temporal estimate of your action than if the app actually opened (though prediction * Felicitas V.

of what will happen induces a small shift in perceived action time as well, Moore & Haggard, 2008). Likewise, if you watched your screen and an app opened without your involvement, you would have a more accurate estimate of the time the app opened than if you actively pressed an icon to open the app. Due to the lack of explicit awareness of such perceptual shifts, temporal binding is an implicit measure for the sense of agency, i.e., the conception of the sel
