This document summarizes and analyzes several theories shown in different films, including the Elaboration Likelihood Model, Social Penetration Theory, Uncertainty Reduction Theory, Attribution Theory, Expectancy Violation Theory, and Cognitive Dissonance Theory. For the film "Ganito Kami Noon, Paano Kayo Ngayon", the Elaboration Likelihood Model is highlighted as particularly relevant, with examples of how characters use the central and peripheral routes of persuasion in their decision-making. The film also depicts the national identity of Filipinos and their treatment under Spanish and American colonization during the past eras in the Philippines.
