What aspects of audiovisual media are responsible for the viewers' subjective perception of duration? What behavioral and neural mechanisms activated by audiovisuals are responsible for the perception of temporality? What are the functions of different styles of film editing in managing subjective time perception? This paper presents the theoretical premises and the results of the pilot phase of a research aimed at exploring the audiovisual spectator’s subjective perception of time. The methodological framework adopted for this research is that of "Neurofilmology", a method that combines theoretical research, textual analysis and experimental findings. Relying on a phenomenological approach to time consciousness and on a neurophenomenological approach to the experience of narrative time, we discuss the role of complex neural mechanisms of subjective judgments of time duration. In order to delve into these issues, we also share and discuss the first results of a laboratory experiment conducted at the Università Cattolica of Milan in cooperation with a team of neuro-psychologists.
