Why a page can become a memory cue
Memory does not store words in isolation. When you try to recall something you read, your mind may also retrieve details about where it appeared: near a chapter opening, beside a diagram, or low on a particular page. Those details act like landmarks, helping you find the passage again mentally as well as physically.
A paper book keeps those landmarks steady. Its pages have fixed boundaries, and its thickness changes as you move through it. The page in your hands, the position of a paragraph, and the growing stack of pages already read can all help place an idea within the book.
What scrolling changes
On a scrolling screen, text moves through a window. Depending on the device and settings, the same passage may appear in a different place after a change in font size, screen orientation, or layout. The reader can still remember the words, but may have fewer stable spatial clues for recalling where they encountered them.
That difference matters most when a reader relies on location to retrace an argument or revisit a detail. It does not mean every paper book is easier to remember than every digital one: fixed-page layouts and bookmarks can provide screen-based landmarks, too. The useful distinction is whether the reading format gives memory a consistent place to attach the words.
