摘要	Cultivation differential analysis is the analytic core of cultivation theory: it compares the social-reality beliefs of heavy television viewers with those of light viewers to estimate how much exposure to television's recurrent messages 'cultivates' a worldview. The cultivation differential is the percentage-point gap between heavy and light viewers in endorsing a television-consistent belief, examined net of demographic controls and refined by the concepts of mainstreaming and resonance.	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.
