Intentional or temporal binding as a proposed measure of the sense of agency is subject to ongoing research and debate. Current research revolves mainly around factors increasing or reducing binding while empirical findings and theories regarding its underlying cognitive and neural mechanisms lag behind. In this study we test the theory that temporal binding in the Libet-Clock task is based on spatial working memory processes. The idea stems from anecdotal reports of participants in prior studies using the Libet-Clock to measure binding. They mentioned that the clock hand position during the action (button press) is difficult to ignore when asked to judge the clock hand position during the outcome (a tone). The Libet-Clock task is bascially a visuo-spatial (working) memory task in which clock hand positions marked by events must be remembered. Therefore, two cognitive processes corresponding to this reported problem to inhibit an irrelevant clock hand position may be proactive and retroactive interference within the spatial working memory rather than a change in time perception. To test this assumption, at least 30 participants (exact sample size determined by Bayes factors) will perform the Libet-Clock task and a similar task in which the displayed positions during the action and outcome are not correlated with time. If the assumption is true binding should occur in both tasks. Additionally, we will use a visuospatial n-back task to measure spatial working memory performance which should correlated negatively with the binding in both binding tasks. Data will be collected in time for the conference.
