Abstract：
:The praxis system comprises a network of brain regions dedicated to complex skilled movements. Following suggestions of a female advantage on learned movements (Chipman and Hampson in Neuropsychologia 44(12):2315-2329, 2006), we investigated how males and females acquire skilled movements. Subjects viewed and imitated sequences of hand movements, which were repeated ten times. Subjects' imitations were captured by a data glove, and the temporal and spatial characteristics of the imitations were compared to the model sequence. We propose an account of the computations required for imitating hand movement sequences and define the errors that may arise from failures at these computations. Our results demonstrate a female advantage in the acquisition of hand movement sequences and show that this sex difference is accounted for by a female advantage in planning, rather than an advantage in execution or online control. Further, the female advantage is specific to the production of items within a sequence and does not affect the proper ordering of items. Our findings have important implications for sex-sensitive instructional strategies, as well as for understanding the human praxis system.
