The Ten Minute Hold
The Notre Dame group pooled 142 tests in January. The lift is small on its own. Age makes it larger, and past 60 the gain runs close to three times what a young adult gets.

And the gain sticks. The first big trial gave older adults a story, then ten quiet minutes. Recall was still up a week later.

Load it by ear: play the lesson out loud rather than read it. |
|
|
Say it back: the moment it ends, tell the room what you got. |
|
|
Set a timer: eight to twelve minutes is the range used in trials. |
|
|
Shut your eyes: lights low, phone face down, and no task at all. |
|
|
Let the mind roam: bored is fine, but stay awake. |
|
|
Speak it again: talk beats key taps at the end of the hold. |
Step two is not filler. A quick test right after learning took the older adult gain from 0.35 up to 0.70. Sound helps as well, since heard words pool at 0.38 and read words at 0.13.
WITH QUICK TEST: g = 0.70 · WITHOUT: g = 0.35 · HEARD: g = 0.38 · READ: g = 0.13

Here is the thing about the phone rule. A 2020 trial found that a scroll after learning cost people recall. But a 2025 team ran it again and found no such gap. So keep the screen away as good sense… the eyes-shut part is what the data backs.
