The exact change

Before

"The older brain processes differently, not necessarily worse. Experience changes what the brain pays attention to and how it integrates information." - Laura Carstensen, Stanford Center on Longevity

After

"The older brain processes differently, not necessarily worse. Experience changes what the brain pays attention to and how it integrates information." - a framing consistent with Laura Carstensen's research at the Stanford Center on Longevity

Suggested change

De-attributed the quote to avoid presenting unverified wording as a direct quotation.

Why this is better

The exact wording of this quote could not be verified in any accessible source, though the sentiment matches Carstensen's published research (e.g. her 2011 book A Long Bright Future and socioemotional selectivity theory). Presenting unverifiable exact wording as a direct quotation risks misattribution, so it was reframed as a paraphrase.
