The authors read stronger tracking as possibly a bias towards perceptually bound rather than conceptual processing, which they say may hinder emotional functioning and strategic engagement with the environment. If it holds, it suggests that more alignment with the environment is not always beneficial for cognition and mood.","findings":["Connectivity variability evoked by perceptual and conceptual changes in a film increased from young to older adulthood, but its coupling to concrete features was stronger at younger ages.","Default mode regions such as the angular and middle temporal gyri supported connectivity reconfiguration at narrative event boundaries and stronger coupling to concrete features.","Fluid intelligence was directly linked to brain-environment alignment but only indirectly to connectivity variability itself."],"terms":[{"term":"functional connectivity (FC)","means":"The degree to which activity in different brain regions rises and falls together over time, measured here with fMRI."},{"term":"FC variability","means":"How much these patterns of connectivity change from moment to moment."},{"term":"fluid intelligence","means":"The ability to reason about and solve new problems, as opposed to relying on accumulated knowledge."}],"basis":"abstract","abstractFrom":"europepmc","model":"claude-sonnet-5-5","writtenAt":"2026-10-25T16:46:57.147Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-25T16:46:57.147Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
