Presented at the <strong>ICA Annual Conference, 2022</strong>.</p> <p>The article develops a theory of dynamic media effects by showing how news influence depends on issue phase: strongest during initial formation and renewed salience peaks, weaker as perceptions consolidate. Its research design links a five-wave probability-based panel survey to multiple media-content datasets and estimates within-person change using RI-CLPM models, allowing the article to test when media exposure shapes public perceptions rather than only whether media and opinion are associated.</p>
