Resumen:
The interpretation and prediction of the future course of observed ctions is vital for social interaction since it allows people to efficiently coordinate their moves to achieve a common goal. However, little is known about the neural underpinnings of this high-level phenomenon. In the present study, event-related potentials (ERPs) were recorded in elite Tango dancers (n = 25), beginners (n = 28) and naives (n = 27). Participants were instructed to watch 150 videos and to classify them into one of two categories (correct or incorrect, in this latter case, the error could be subtle or gross) as quickly and accurately as possible. ERPs in tango Experts revealed an early positivity, reduced in Beginners and absent in Naives. Following this peak, Experts elicited a more positive P300 compared to Beginners and Naives. The N400-like showed more negative amplitudes for incorrect actions. Finally, within Experts, SlowWaves were strongly affected in amplitude by action congruence with more positive ERPs for congruous vs. incongruous actions. Overall, these results suggest that Experts (followed by Beginners) were able to anticipate inconsistencies during action observation. Moreover, only experts were able to early discriminate between gross and subtle errors, suggesting that expertise significantly modulates action perception. Taken together, these findings suggest the comprehension of complex joint actions is significantly modulated by the expertise and motor repertoire of the observer.
