The expression, experience, and social consequences of guilt: A cross-cultural study Eglantine Julle-Danière Thesis submitted in partial fulfilment of the requirements for the award of the degree of Doctor of Philosophy of the University of Portsmouth. September 2019 The face is a picture of the mind Cicero (46, BCE) Abstract Guilt arises when someone feels s/he did something wrong; it is classified as a moral, self- conscious emotion and is one of the most social emotions that people experience throughout life. A facial expression of guilt may have evolved in humans to indicate one’s willingness to make amends. In this thesis, I investigate the form and social value of facial signals associated with guilt. First, I explored the facial signals reliably associated with guilt, using a bottom-up approach, and examined the facial movements associated with the perception of guilt. I found that self-reported guilt was associated with upper lip movement and neck touching, but the perception of guilt was associated with frowning and face touching. Second, I considered the influence of contextual information and methodology on the perception of guilt. The study revealed that the context helped the interpretation of a facial expression of guilt. However, people did not reliably identify a facial signal of guilt when using emotion or action tendency labels, but did so using dimensional ratings to a certain extent. Third, I explored the tendency people have to mislabel facial displays of guilt by looking at the eye fixation patterns. I found that ‘guilt’ facial expressions were examined similarly to basic emotion displays and this could indicate that the emotional display of guilt was perceived as a unique mix of primary emotions. Finally, I considered the social consequences of guilt between pairs of friends. In this study, feeling guilty increased the motivation to repair wrongdoing regardless of friendship while observing guilt in others led to a punishment effect, modulated by friendship. Overall, this thesis supports the idea that guilt has an important social function and provides the first evidence that facial signals can be associated with the experience of guilt. These data build on previous research on the perception of secondary emotions and the importance of facial signals in social interactions. i Contents list Abstract ...................................................................................................................... i Contents list ............................................................................................................... ii Declaration ................................................................................................................ v Acknowledgements ................................................................................................... vi Dissemination of research from this thesis .............................................................. viii List of tables .............................................................................................................. x List of figures ............................................................................................................ xi 1.
