Abstract:

Mu rhythms are EEG oscillations in the 8–13Hz recorded at sites located roughly over the sensory-motor cortex. There is reliable evidence that the amplitude of mu rhythms is reduced when the participant performs a motor act (mu suppression). Recent studies found mu suppression not only in response to actual movements but also while the participant observes actions executed by someone else. This finding putatively associates the mu suppression to the activity of a mirror neurons system which, in humans, has been suggested to contribute to social skills. In the present study we explored the effects of different levels of social interaction on mu suppression. Participants observed dynamic displays of hand gestures performing actions used in the Rock–Scissors–Paper game. In different blocks, participants passively viewed identical video clips with no game context and in the context of a game, or while being actually engaged in the game either by imagining actions or by actual playing.
