Figure 3: Graphical representation of the sLORETA results comparing the differences of the target-P2 between test sessions exemplarily for the independent group test including the cognitive training group and the no-contact control group. Similar results were obtained when including the social control group. The blue colour indicates local maxima of lower activation in the first compared to the second test session for the cognitive training group in the right lingual and parahippocampal gyri, which may explain the amplitude difference of the P2 between sessions in the tested interval surrounding the P2 peak.
