摘要	Cultivation analysis is the research method underlying cultivation theory, which holds that long-term, cumulative exposure to television gradually shapes viewers' conceptions of social reality. Developed by George Gerbner and Larry Gross in the 1970s as part of the Cultural Indicators project, it combines a systematic content analysis of recurring media messages with survey comparisons of heavy versus light viewers to estimate how much television 'cultivates' a shared, often distorted, view of the world.	Manifest content analysis is a quantitative research technique that systematically counts the explicit, surface-level features of communication messages — words, sources, themes, images, or actors that are directly visible in the text or media artifact — according to a predefined coding scheme. Rooted in Bernard Berelson's classic definition of content analysis as the 'objective, systematic, and quantitative description of the manifest content of communication,' it is one of the foundational empirical methods of mass communication and media research.
