The present study investigates the mechanisms behind interpersonal coupling by using movement sonification. Therefore the impact of kinematic and dynamic sonifications on movement synchronization and perceptual accuracy were compared. In a first session, the participants rowed on an indoor rower to sonifications of another person. In a second session, they listened to sonifications of their own and to those of other persons and estimated rowing frequencies. The results permit conclusions about the structure of motor representations and give perspectives for sport practice.
