Note: All significant results (in bold) and partial effects (indicated by a Inline graphic sign) are presented. Effects without significant partial effects perelectrode (in grey) are not reported in the text. emo = emotion; fil = filter type; pos = position of bilateral electrodes; lat = laterality; »» = earlier than; > = larger than.
