Abstract(in English) Becoming proficient in a motor skill like the playing of a musical instrument implies less necessity to rely on feedback. In a sequential hand reaching task, we investigated the coordination between hand and eye movements. We found that the number of saccades per trial decreased significantly over a long time of learning, resulting in the emergence of a stereotype sequence with selective saccades. Which targets could be neglected for a skillful performance? Our results suggest that the reduction of eye movement may depend not only on the geometry of the sequence, but also on the chunking of memory.
