EP mapping of response‐locked EEG signals in the OBT and LAT. (a) Segments of stable map topographies in the OBT with EPs computed locked to the response of the participants and averaged over all perspectives. This segmentation yielded a MapOBT‐MOTOR only in the OBT, but not in the LAT, and hence confirms that brain activity after the initial stimulus‐locked EPs (see Fig. 3a) differs between the OBT and LAT. (b) Similar to MapOBT the duration of MapOBT‐MOTOR was longer for higher rotation angles, which suggests the presence of at least one more mental transformation process in addition to the activity we described at 330 ms.
