This thesis deals with the study of dissociative identity disorder (DID) in contemporary media representations. The movie Split (2016, Shaymalan), the series Mr. Robot (2015-2019, USA Network) and the series Moon Knight (2022, Marvel) are being analysed. DID is an psychological disorder characterized by a type of dissociation in which a person experiences two or more distinct identities called alters, as well as recurrent amnesia. DID is often depicted in popular culture movies and tv shows, and its portrayal is often problematic, sensationalized, exaggerated, and untrue. The main methodology used is the analysis of visual discourse and the comparison of the analysis with the read literature and sources. The goal is to see how and in what way the disorder is portrayed, i.e. whether there are misconceptions about the disorder through the movie or tv show we are studying, whether the portrayals are harmful and bad, whether they promote myths and stereotypes. Furthermore, we study how this image affects the society that consumes popular culture and what such representation says about the popular culture itself to which the media representation belongs. The movie Split presents a negative portrayal full of myths and stereotypes, the tv show Mr. Robot brings a positive portrayal full of empathy and understanding, and the Moon Knight tv show brings both a positive and negative portrayal full of encouragement and potential. The obtained results of the analysis indicate a significant shift in the presentation of DPI, a shift towards empathy, sincerity and humanity.
