Wearing hearing aids doesn’t seem to make your memory or thinking skills better on tests, even though you might feel like it’s easier to listen and understand people.

Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim uses 'associated with,' which correctly reflects correlational findings from observational or quasi-experimental studies. It does not imply causation, which is appropriate since cognitive changes may be influenced by confounders (e.g., social engagement, depression). The dual outcome (objective cognition unchanged, perceived effort reduced) is nuanced and accurately captured. No overstatement is present.
More Accurate Statement
“Among hearing-impaired adults, hearing aid use is associated with no statistically significant change in objective cognitive test scores, despite self-reported reductions in perceived listening effort.”

Speech understanding in quiet and noise, with and without hearing aids
The study found that when people with hearing loss use hearing aids, they feel like listening is easier, but their brain test scores don’t get better — which is exactly what the claim says.
