The document discusses several theories related to media consumption and effects: - The effects model suggests media has negative influences on audiences who passively receive messages. - The hypodermic needle model also views audiences as passive, suggesting media messages are directly "injected" into audiences like injections. - Uses and gratifications theory takes an audience-centered approach, arguing audiences actively seek out specific media to fulfill needs. - Reception theory holds that meaning comes from the interaction between audiences and media texts, and is influenced more by contextual factors than just the text itself. Audiences play an active role in interpreting meaning.
