Table 4.
All main within-subject effects and their interactions for the factors ELECTRODE, GRID, and EMOTION and main between-subject effect for the factor CONTEXT, and its interaction with EMOTION of the analysis of variance (F-value, P-value); significant findings are marked in bold; if assumption of sphericity is violated, Greenhouse–Geisser corrected P-values are printed

Notes: For reasons of clear presentation this table only contains selected main and interaction effects. All main and interactive effects of the within-subject factors were printed in order to give an overview of ERP responses in our task. For the between-subject factor CONTEXT only the main effect and the interaction effect with EMOTION are printed because this is most relevant regarding our main hypothesis.
Abbreviations: EPN, early posterior negativity; ERP, event-related brain potential; LPC, late positive complex.
