Reply to Deecke and Soekadar: Do conventional readiness potentials reflect true volitionality?

Abstract

We would like to thank Deecke and Soekadar (1) for their insightful comments on our paper (2). We agree that the voluntary movements in our study were not fully unconstrained. A green light was used to indicate to the participant that a trial had started. This indeed raises the question whether our results generalize to movements without external cueing. Please note that, in our study, the green light is not a response trigger. It indicates the onset of a self-timed waiting period that is followed by an open-ended period during which movements could be freely made. In contrast to many studies on the readiness potential (RP), our study did not require participants to move within a specific time. Thus, … [↵][1]1To whom correspondence should be addressed.
