Influencing romantic decisions with real time smile transformations


The study of dyadic social interactions often relies on either the recording of free conversations or on the use of research confederates and scripted dialogs. On the one hand, the use of free conversations is useful to observe the conversational dynamics and behaviours that are involved in specific tasks. However, these studies are only correlational. On the other hand, experiments using scripted interactions or research confederates, are useful for experimental control, but limited to their low ecological validity. In this talk, I will present a new research paradigm, where we are able to manipulate participants’ facial expressions in real time using digital signal processing algorithms. Specifically, I will present an experiment where we covertly manipulate participants’ smiles in real time during a speed dating task. With this methodology, I will show how expressive alignment can influence romantic decisions and social dynamics in freely interacting participants. I will argue that this new methodology gives researchers the unprecedented ability to have high experimental control during free and unscripted social interactions.
