The document discusses several theories related to mass communication and media influence:
1) The two-step flow theory asserts that information from media moves in two stages - first to opinion leaders who then pass on their interpretations to others in their social networks.
2) Uses and gratifications theory focuses on what audiences do with media rather than what media does to people. It assumes audiences actively interpret and use media to fulfill needs.
3) Maslow's hierarchy of needs suggests people are motivated to fulfill basic physiological and safety needs before pursuing higher psychological and social needs.
