Libet et al. (1983) revealed that brain activity precedes conscious intention. For convenience in this study, we divide brain activity into two parts: a conscious field (CF) and an unconscious field (UF). Most studies have assumed a comparator mechanism or an illusion of CF and discuss the difference of prediction and postdiction. We propose that problems(More)
To reveal the fundamental skills involved in slacklining, this study examined a hypothesis regarding single-leg standing on a slackline. In the field of practice, instructors teach learners how to maintain balance on a swinging flat belt (slackline), such as by moving their hands in parallel. We hypothesized that bimanual coordination in the horizontal(More)
Finger-tapping experiments were conducted to examine whether the dynamics of intrapersonal and interpersonal coordination systems can be described equally by the Haken-Kelso-Bunz model, which describes inter-limb coordination dynamics. This article reports the results of finger-tapping experiments conducted in both systems. Two within-subject factors were(More)
To reveal the differences between intra-and inter-personal systems in terms of the perceptual effect on the stability of inter-limb coordination, the present study conducted a finger-tapping experiment in in-phase and anti-phase mode. We investigated a between-subjects factor (the intra-/inter-personal condition), and a within-subject factor (the phase(More)
