Rashomon is a Japanese film that won the Venice Film Festival in 1951. This film tells about some of the perceptions of people’s memories that were involved in a murder scene and also the honesty of each person. Oscar Lewis (1914-1970), an American anthropologist known for his clear depiction of the lives of slum dwellers in Mexico, used the Rashomon technique in the way he saw through the eyes of the family’s perception of each of its members. The Rashomon technique gives more insight into the individual psychology. The relationship between the research methodology and the Rashomon technique is that it refers to the methods of positivism and interpretivism analytical approaches, because those methods are believed to be appropriate as a strategy for conducting research and ways of understanding the reality that happen in the world.
