Disrupting the speech motor network: Exploring hemispheric specialization for verbal and manual sequencing using a dual-task approach.

This novel behavioral data supports theories of a motor-based gestural origin for language and indicates that speech production is more sensitive to the effects of increased processing requirements than are motor skills.
