| 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.
