“…The footage was analysed in the biosensor platform Imotions using the facial expression coding software Affectiva. This software has been used in publications on a range of topics including, for example, socially transmitted placebo effects (Chen et al, 2019) and the impact of safety system warnings on people's emotions (Fahim et al, 2019). The percentage of time spent in a negative emotional state was calculated by Affectiva software according to the amount of time displaying negative emotion out of the total time recorded for stimulus.…”

Although there has been a proliferation of research and policy work into how nudges shape people's behaviour, most studies stop far short of consumer welfare analysis. In the current work, we critically reflect on recent efforts to provide insights into the consumer welfare impact of nudges using willingness to pay and subjective well-being reports and explore an unobtrusive approach that can speak to the immediate emotional impacts of a nudge: automatic facial expression coding. In an exploratory lab study, we use facial expression coding to assess the short-run emotional impact of being presented with calorie information about a popcorn snack in the context of a stylised ‘Cinema experience’. The results of the study indicate that calorie information has heterogeneous impacts on people's likelihood of choosing the snack and on the emotions they experience during the moment of choice which varies based on their level of health-consciousness. The information does not, however, affect the emotions people go on to experience while viewing movie clips, suggesting that the emotional effects of the information are short-lived. We conclude by emphasising the potential of automatic facial expression coding to provide new insights into the immediate emotional impacts of nudges and calling for further research into this promising technique.
