Abstract concepts like beauty and friendship are grounded in sensory-motor and social brain systems, review finds
AnnaCiaunica · x · 2026-11-12
A CORTEX review by Kiefer & Trumpp challenges the assumption that abstract concepts require purely amodal or linguistic representations. Within a hybrid grounded-cognition, multiple-representation framework, it surveys neuro evidence that concepts like beauty and friendship recruit sensory-motor, mentalizing, and social-interaction brain systems alongside language and amodal semantic hub regions. Different modal circuits engage depending on each concept's semantic content, highlighting the heterogeneity of abstract concepts; open questions include quantifying each circuit's contribution and modeling impairment patterns in patients.
