The claim says that the match between these shifts and concrete, perceptual features of a film, such as what is on screen, was tighter in younger adults. This is set against FC variability itself, which rose with age. In the paper, such coupling is treated as a possible marker of how the brain tunes to its surroundings across the adult lifespan.","findings":["FC variability evoked by concrete perceptual changes and by abstract conceptual changes in a situation increased from young to older adulthood.","Stronger coupling between moment-to-moment FC variability and concrete environmental features predicted poorer fluid intelligence and greater affectively driven environmental vigilance.","Younger and older adults showed different network communication profiles: more default mode integration in older age, and more information flow across attention and control networks in youth."],"terms":[{"term":"functional connectivity (FC)","means":"The degree to which activity in different brain regions rises and falls together over time, used as a measure of how regions communicate."},{"term":"FC variability","means":"How much these connectivity patterns change from moment to moment."},{"term":"concrete environmental features","means":"Perceptual, here-and-now properties of the film, as opposed to abstract features such as the narrative storyline."}],"basis":"abstract","abstractFrom":"europepmc","model":"claude-sonnet-5-5","writtenAt":"2026-10-25T17:16:36.358Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-25T17:16:36.358Z","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.
