From tactile perception to tool use: on the sensorimotor grounding of semantics and syntax

Véronique Boulenger

Résumé

n the framework of embodied cognition, action words have provided a fantastic opportunity to investigate the grounding of word meaning in the sensorimotor system. Motor cortical regions are activated during processing of action-related words or sentences [1], even in an idiomatic context [2], and action word reading can interfere with or facilitate motor performance. Studies have also examined the embodiment of language in the perceptual system (mostly vision, but also audition, olfaction and taste), yet the case of words referring to touch remains largely overlooked. In this talk, I will first present evidence for functional links between processing of words denoting tactile sensations and tactile perception: reading tactile-related verbs can speed up the mere detection of tactile stimulations [3]. The second part of the talk will be dedicated to another language domain, syntax, which has also been proposed to be embodied [4]. I will present new fMRI evidence that tool use, which adds a further hierarchical level into the motor plan, shares neural substrates with syntax in language in the basal ganglia [5]. Behaviorally, this is reflected by cross- domain learning transfer: training one ability specifically improves the other. These findings suggest the existence of a supramodal syntactic function shared between language and motor processes.
