Abstract Human vocabularies include specific words to communicate interpersonal behaviors, a core linguistic function mainly afforded by social verbs (SVs). This skill has been proposed engage dedicated systems subserving knowledge. Yet, neurocognitive evidence is scarce, and no study examined spectro-temporal spatial signatures of SV access. Here, we combined magnetoencephalography time-resolved decoding methods characterize the neural dynamics underpinning SVs, relative nonsocial (nSVs), via lexical decision task. Time-frequency analysis revealed stronger beta (20 Hz) power decreases for SVs in right fronto-temporal sensors at early stages. Time-resolved showed that oscillations significantly discriminated nSVs between 180 230 ms. Sources this effect were traced anterior superior temporal gyrus (a key hub conceptual knowledge) as well parietal, pre/motor prefrontal cortices supporting nonverbal cognition. Finally, representational similarity analyses observed patterns specifically predicted verbs’ socialness, opposed other psycholinguistic dimensions such sensorimotor content, emotional valence, arousal, concreteness. Overall, verbal conveyance socialness seems involve distinct neurolinguistic patterns, partly shared more general sociocognitive lexicosemantic processes.
