Audience Measurement
Aided Recall
A research methodology used to test audience memory retention of advertisements by providing specific prompts or hints to the respondent.
What is Aided Recall?
Aided Recall surveys ask respondents questions like 'Do you remember hearing an advertisement for Brand X in the last week?' — providing the brand name as a cue. Unaided Recall, by contrast, asks open-ended questions and accepts only unprompted mentions. Aided Recall almost always returns higher scores than Unaided, but it measures a different, weaker form of memory.
Post-campaign, brand-lift studies typically use a combination: Unaided Recall is the gold-standard proof of a campaign's cognitive impact; Aided Recall demonstrates minimum-threshold exposure. When Aided Recall lifts but Unaided does not, it usually means the ad was heard but not remembered spontaneously — a signal to revisit creative strength rather than media delivery.
Why it matters
Used heavily in post-campaign brand lift studies to prove that a radio or TV campaign successfully altered consumer perception.
