Advantages of EEG as a neuroimaging modality. From Sänger et al. (2012). The experiment from Sänger et al. (2012) is an appropriate example when it comes to studying social interaction in an ecological way with a socially engaging task. In this experiment, guitar players were able to see each other’s face, enabling them to perceive each other’s gaze and facial expressions, crucial social cues in human interactions (empathy, theory of mind). Additionally, EEG as a neuroimaging modality is moderately hindering musicians’ movements compared to other modalities such as fMRI and MEG, allowing them to interact in a more ecological manner. Finally, the task choice (music performance) is pertinent for many reasons that we will discuss, but mainly because it is socially relevant: practicing music with someone is a common activity.
