Phase transitions and critical fluctuations in the visual coordination of rhythmic movements between people.

Abstract: By watching each other's lower oscillating leg, 2 seated Ss kept a common tempo and a particular phase relation of either 0° (symmetric mode) or 180° (alternate mode). This study investigated the differential stability of the 2 phase modes. In Experiment 1, in which Ss were instructed to remain in the initial phase mode, the alternate phase mode was found to be less stable as the frequency of oscillation increased. In addition, analysis of the nonsteady state cycles revealed evidence of a switching to the symm… Show more

“…The analysis of the experimental data gathered in our previous study [Lorenz et al, 2011] shows that people also synchronize their arm movements in a goal-directed task which is characterized by the need for precise movements. These findings are in line with previous studies on the topic [Schmidt et al, 1990, Richardson et al, 2005. In general, movement synchronization is found to be a guiding dynamical process which leads to stable coordination patterns in natural HHI.…”

“…They unintentionally rock in synchrony, although different weights attached to the chairs manipulate the frequencies at which they would naturally oscillate without human effort. Similar behavior is observed in tasks in which people have to swing handheld pendulums [Richardson et al, 2005] or are merely moving their legs [Schmidt et al, 1990]. Besides these behavioral effects, synchronization affects social relationships.…”

“…The more long-standing focus on temporal coordination, which can be traced back to when researchers first started comparing intra-and interpersonal coordination about 20 years ago (Schmidt et al 1990), has been fundamental in advancing our understanding of how synchronization between individuals emerges. In addition to synchrony (Richardson et al 2007), recent studies on temporal coordination have also begun to address the mechanisms underlying coordination of non-rhythmical activities and the use of individual strategies to facilitate temporal coordination.…”

“…Schmidt et al (1990) ran a series of experiments asking two participants to swing periodically a pendulum while looking at each other. They actually found in this new problem all the hallmarks of bimanual coordination: bistable dynamics, bifurcation, critical fluctuations, and the like.…”
