You smile and I do not reply. Timing and voluntary suppression of forced smiles towards disliked targets.

The ability to control emotional facial reactions towards interaction partners is an important asset to foster or hinder affiliation. While smiling at positive targets takes no effort, smiling towards outgroups, disliked others and competitors has been shown to be effortful and more often suppressed. In a series of two studies (N=80), we investigated a potential inhibition advantage, indexed via a greater action restraint of emotional facial reactions, towards targets previously paired with negative behavior compared to targets previously paired with good behavior. Analysis of facial muscles via EMG during a facial reaction Go/NoGo task revealed significantly less commission errors towards negative targets. The analysis of the overall muscle activation over time during NoGo trials also reveals a weaker overall magnitude of congruent muscle responses towards the negative target. The results indicate that irrespective of being task irrelevant, the personal attitude towards the target modulated facial responses resulting in stronger congruent reactions towards positive targets.
