A psychological approach to human voluntary movement.
The author argues that movements are planned, executed, and stored in memory as perceptible events, without regard to efferent patterns. Spontaneous bimanual coordination phenomena are hypothesized to originate on a perceptual-cognitive level, with the muscles automatically tuned in service to preferred perceptible movement properties. The perceptual-cognitive system is hypothesized to control skilled complex movements as well. In perceptual-cognitive control, the full potential of the perceptual-cognitive system could be exploited. Thus, movements could be enormously flexible, with a strong potential for improvisation and creativity. An effective representation might be organized in a surprisingly sparse and economic way. In sum, the author argues that a psychological approach is most promising as a possible unifying perspective for understanding human voluntary movements.
