Long-range correlations have been evidenced in a number of experiments, generally using overlearned and overpracticed tasks. The authors hypothesized that long-range correlation could represent the byproduct of learning. They analyzed the series of periods produced by a group of expert and a group of novices during prolonged trials on a ski simulator. Results showed a very low variability in expert's series, as compared to novices. Fractal analyses showed that fluctuations were significantly more structured and correlated in experts. These results suggest that learning could be conceived as the progressive installation of complexity in the system.
Ce texte constitue le prologue du numéro 11 du Journal on Interdisciplinary Methodologies and Issues in Science : Penser l'interdisciplinarité en pratique. L'ensemble des 10 contributions est brièvement présenté à partir des fondements qui font l'interdisciplinarité en pratique : les dispositions des chercheurs, leur posture indisciplinaire et le contexte complexe dans lequel s'opère l'interdisciplinarité.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
