সারসংক্ষেপ	Psychophysiological measurement records the body's continuous responses — heart rate, skin conductance, facial muscle activity, and more — while people are exposed to media, providing real-time, covert indicators of attention and emotion. Reviewed for communication by Ravaja, these measures sidestep the biases of self-report and capture moment-to-moment processing as a message unfolds.	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.
