  1. Paired sample t tests reporting significance and effect size (Cohen's d) of Correctness effects on PE amplitudes, as a function of object type (harmless vs. weapon) across electrode positions: left, medial, right (LMR) and anterior-to-posterior (ACP). N.S. indicates that the higher order interactions were non-significant and did not justify t tests at a given scalp location
