Description
The present study used event-related brain potentials to examine the hypothesis that emotional gestures draw attentional resources at the level of distinct processing stages. Twenty healthy volunteers viewed pictures of hand gestures with negative (insult) and positive (approval) emotional meaning as well as neutral control gestures (pointing) while dense sensor event-related potentials (ERPs) were recorded. Emotion effects were reflected in distinct ERP modulations in early and later time windows. Insult gestures elicited increased P1, early posterior negativity (EPN) and late positive potential (LPP) components as compared to neutral control gestures. Processing of approval gestures was associated with an increased P1 wave and enlarged EPN amplitudes during an early time window, while the LPP amplitude was not significantly modulated. Accordingly, negative insult gestures appear more potent than …
