Working Memory for Ballet Moves and Spatial Locations in Professional Ballet Dancers

The aim of the present study was to investigate working memory for ballet moves in expert dancers. Experiment I showed that a concurrent spatial task did not interfere with the recall of a sequence of ballet moves when these were encoded alone without being associated with spatial locations. Experiment 2 showed that a concurrent motor task selectively interfered with the recall of ballet moves while neither a concurrent motor task nor a spatial task affected recall of the specific locations where each ballet move had to be performed. Experiment 3 showed that spatial interference affected recall of sequences of locations when these were encoded alone. Finally, in Experiment 4, a similarity effect for patterned ballet movements was shown. Taken together results show that spatial interference does not affect short-term memory for ballet moves thus suggesting that working memory might contain a system for motor configurations.
