概要	Media system dependency analysis operationalizes Ball-Rokeach and DeFleur's 1976 theory that media effects are strongest when individuals depend heavily on the media system to attain personal goals — understanding their world, orienting their actions, and finding diversion. The method surveys the intensity of these dependency relations and relates them to cognitive, affective, and behavioral effects of media.	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.
