This article provides data from a contemporary replication of Libet's experiment. For the methodology, results and discussion of the replication, see the article "Libet's Experiment: A Complex Replication" (Dominik et al., 2018).
Three types of data are presented in this article: (1) introspective reports (M, W and S), (2) EMG onset times relative to a mouse click or to the target time in tasks with a movement at pre-set time and (3) relevant averaged EEG data.
