Outline of Final Research Achievements

Human (and animal) perceptual activities can be characterized as active sensing systems. In this project, human exploratory movement involved in dexterous skills was characterized in terms of multi-scale temporal structures to better understand the assembly of such systems. The reanalysis of exploratory behavior using a hammer involved in stone beads production in India revealed the presence of long-range, power-law correlations, as part of multiplicative cascades operating over a wide range of time scales. In the unfamiliar condition using unusual material, the hammer-wielding, exploratory behavior of highly skilled experts displayed a significant increase of long-range temporal correlations, whereas that of less experts exhibited a significant loss of long-range correlations and reduced heterogeneity of scaling properties over time, which robustly discriminated the groups with different skill levels.
