Résumé :
In neuroscience, grounded cognition research has been dominated by behavioral and brain activation studies on action semantics, with healthy individuals, using highly artificial materials and prioritizing inferential statistical methods. In this presentation, I will introduce a framework to expand the field beyond this standard approach. First, I will describe our multi-methodological approach, integrating classic behavioral paradigms, naturalistic materials, and natural language processing with neuroanatomical, hemodynamic, electrophysiological, neuromodulatory, and intracranial techniques (all supported with machine learning tools for data analysis). Second, I will review evidence on action semantics, revealing new signatures across behavioral, neural, genetic, and experiential levels. Third, I will show that the recycling of non-linguistic mechanisms during language processing extends beyond primary sensorimotor systems, with critical evidence on the reactivation of face-processing and inhibitory mechanisms during processing of facial concepts and negation markers, respectively. Fourth, I will summarize new findings on social semantics, an underexplored domain that is related to diverse socio-behavioral systems and interpersonal experience. Crucially, all of these themes include evidence from clinical populations, leading to translational innovations for detecting and differentiating brain diseases. To conclude, I will describe new initiatives to leverage the framework’s translational potential. Overall, I will contend that grounded aspects of meaning may be more pervasive than we imagine, so that no dimension is irrelevant to make sense of sensemaking.
