概要	Media priming is the process by which news attention to some issues, and not others, changes the standards people use to evaluate leaders, policies, or events. Demonstrated experimentally by Iyengar and Kinder in News That Matters, the priming experiment manipulates which issues the news emphasizes and tests whether those issues subsequently weigh more heavily in audiences' judgments — the natural extension of agenda setting from importance to evaluation.	Elaboration likelihood analysis applies Petty and Cacioppo's 1986 Elaboration Likelihood Model (ELM) to study persuasion through experiments that cross message argument quality with peripheral cues under varying levels of audience motivation and ability to think. It identifies whether attitude change travels the central route — effortful scrutiny of arguments — or the peripheral route, reliance on simple cues like source attractiveness or message length.
