Bedia, M. G., Aguilera, M., Gomez, T., Larrode, D. G., & Seron, F. (2014). Quantifying long-range correlations and 1/f patterns in a minimal experiment of social interaction. Frontiers in Psychology, 5, 1281. doi:10.3389/fpsyg.2014.01281
Together with Manuel Bedia, Tomás Gómez, David Larrode and Francisco Serón we just published a new paper presenting our results in applying 1/f and long-range correlation measures in social interaction dynamics. The paper is based on the Perceptual Crossing experiment, a minimal experimental setting reducing social interaction to one dimension. We find that human-human interaction presents a signature of long-range correlations not present when humans interact with artificial agents. This difference in signatures is not found between the individual behaviour of humans and artificial agents, suggesting that the qualitative difference of genuine social engagement lies in a shared space of interaction rather than in individual behaviour.
