Stimuli, experimental procedure and evoked responses in Experiment 1
(A) Participants were presented with RDKs in three conditions. In the full sequence trial condition, four successive RDKs were presented. In the start-or end-only condition, only the first or last RDK in the sequence was presented at the beginning of the trial. (B) During MEG scanning, the participants were presented with two functional localizer runs (i.e., functional localizer phase) before providing any sequence information. Next, they were exposed with four full sequence runs (i.e., exposure phase). Finally, in the main phase, full sequence, start-and end-only trials were presented in a pseudo-randomized order. (C) Evoked brain responses as a function of time relative to trial onset in the full sequence, start-and end-only trial conditions, respectively. Bold black lines at the bottom indicate temporal clusters in which they reached significance when compared to the pre-stimulus baseline. Inset figures at the top-right corner show the peak amplitudes during the four corresponding RDK intervals after baseline correction.
