Web2 20 1. Contralateral and ipsilateral waveforms 21 The difference waveforms for the CDA component in the main text were determined 22 by calculating the mean contralateral and ipsilateral ERP activity recorded at the 23 electrode pool P9/10, P7/P8, and PO7/8. Here, we provide the separate contralateral 24 and ipsilateral waveforms for each condition, for … ERP waveforms consist of a series of positive and negative voltage deflections, which are related to a set of underlying components. Though some ERP components are referred to with acronyms (e.g., contingent negative variation – CNV, error-related negativity – ERN), most components are referred to by a letter (N/P) indicating polarity (negative/positive), followed by a number indicating either the latency in milliseconds or the component's ordinal position in the waveform. For instan…
