The role of dorsal anterior cingulate cortex in dynamic attitude changes in naturalistic settings.
Article in Communications biology, 2026. 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
Attitudes change gradually and spontaneously in daily life, yet the neural mechanisms supporting such dynamic shifts remain poorly understood. Leveraging naturalistic fMRI paradigms across two studies, we investigated how neural dynamics track and implement attitude change during exposure to persuasive arguments. Our findings highlight the dorsal anterior cingulate cortex (dACC) as a central hub in this process. Individuals with more similar trajectories of attitude change exhibited greater similarity in the temporal dynamics of dACC activity and its functional connectivity with other brain regions, particularly the default mode network (DMN). These neural dynamics further predicted whether an individual changed their attitude over time, and at the precise moment of change, dACC-centered connectivity predicted the direction of that change. Additionally, individuals with higher intolerance of uncertainty (IU) showed stronger coupling between neural and behavioral similarity, suggesting that IU may serve as a trait-level modulator of this neural process. Together, our findings provide a dACC-centered, process-level account of the neural mechanisms underlying dynamic attitude change, bridging the gap between controlled laboratory research and real-time, naturalistic attitude change in daily life.
