Spatio-temporal activity of brain electrical sources during processing of abstract social concepts.
Article in Social cognitive and affective neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
concepts frequently refer to socialness, i.e. knowledge about interactions between people. Grounded cognition theories propose that such social concepts are represented in brain circuits involved in processing social interactions. The present event-related potential study investigated the time course of electrical brain activity in response to abstract social concepts compared to abstract control concepts presented during a lexical decision task. Analysis of estimated volume source activity revealed increased activity to social concepts in the left insula with an onset of 216 ms and somewhat later in frontal brain areas (292 ms). These regions are associated with empathy and mentalizing, respectively. Social concepts also enhanced activity in the left anterior temporal lobe (292 ms), a heteromodal semantic hub supporting semantic integration. Later (438 ms), social concepts activated a fronto-parietal brain network typically engaged during social interaction. Early activity increases in social cognition brain networks (<300 ms) most probably indicate access to conceptual features, while later activity increases may reflect semantic elaboration. In accordance with hybrid models of conceptual cognition, processing of abstract social concepts is grounded in brain regions associated with empathy and social interactions, complemented by semantic integration processes in heteromodal semantic hub areas.
