概要	The experience-sampling method (ESM), also called ecological momentary assessment, prompts participants at sampled moments throughout daily life to report what they are doing, using, and feeling right now. Applied to media research, it captures media use and its momentary correlates — mood, context, motivation — in real time and in situ, minimizing recall bias and revealing how media and experience interrelate moment to moment.	The uses and gratifications survey is the dominant audience-centered method in communication research, asking not what media do to people but what people do with media. Codified by Katz, Blumler, and Gurevitch in 1973, it treats audiences as active agents who select media to satisfy social and psychological needs, and it measures those motives and the rewards obtained through structured self-report scales.
