学习双手协调任务（同步到视觉指定的相位关系）进行了研究，作为一个动态的过程超过5天的实践所需的相位模式。在练习前、练习中和练习后，对5个学生的协调动力学（通过集体变量，相对相位表示）的吸引子布局进行了系统的探索。根据初始协调动力学（所谓的内在动力学）和要学习的模式（称为行为信息，它作为协调动力学向所需定相的吸引子）之间的关系，相图中发生了质的变化，伴随着失去稳定性（相变）的定量证据。这种影响持续超过1周。由于学习而产生的变化的性质（例如，突然与渐进）是由行为信息和内在动力之间的合作或竞争相互作用引起的。
Learning a bimanual coordination task (synchronization to a visually specified phasing relation) was studied as a dynamical process over 5 days of practicing a required phasing pattern. Systematic probes of the attractor layout of the 5 Ss' coordination dynamics (expressed through a collective variable, relative phase) were conducted before, during, and after practice. Depending on the relationship between the initial coordination dynamics (so-called intrinsic dynamics) and the Pattern to be learned (termed behavioral information, which acts as an attractor of the coordination dynamics toward the required phasing), qualitative changes in the phase diagram occurred with learning, accompanied by quantitative evidence for loss of stability (phase transitions). Such effects persisted beyond 1 week. The nature of change due to learning (e.g., abrupt vs. gradual) is shown to arise from the cooperative or competitive interplay between behavioral information and the intrinsic dynamics.
