Abstract:
All spoken languages express words by sound patterns, and certain sound patterns (e.g., blog) are systematically preferred to others (e.g., lbog). However, whether those preferences reflect abstract rules or the motor difficulties associated with speech production is unknown. We address this question using transcranial magnetic stimulation and functional MRI. Results show that speech perception automatically engages the articulatory motor system, but linguistic preferences persist even when the motor system is disrupted. These findings suggest that, despite their intimate links, the language and motor systems are distinct. Language is designed to optimize motor action, but its knowledge includes principles that are disembodied and potentially abstract.
