Framing analysis needs theoretical clarification and integration. For this purpose, this paper discusses the theoretical foundations and problematics of framing analysis, explicates the concepts of "frame" and "framing," reviews and analyzes the literatures in three areas of news framing analysis: frames and framing in news representation, framing effects and psychological mechanisms, and the structuring of discursive practices in public life via framing. Synthesizing the literatures in these areas, this paper argues that framing analysis is an area of research on how people interact in the construction of social reality. It offers a unique theoretical perspective that considers cognition, discourse, and practices in an integrated dynamic.
