Description
Cinematographic editing influences how viewers perceive time, yet the psychological and neural mechanisms underlying this phenomenon remain underexplored. This study examined the role of the supplementary motor area (SMA) in shaping temporal perception during film viewing using transcranial direct current stimulation (tDCS). Forty-eight participants were assigned to one of three tDCS conditions (anodal, cathodal, sham) targeting the SMA while watching video clips with varying editing styles (no editing, slow-paced, fast-paced). Participants rated perceived duration, time passage, action speed, and emotional engagement. Results showed that modulation of SMA excitability via tDCS significantly interacted with editing style, affecting temporal and motion-related judgments. These findings demonstrate the SMA’s involvement in temporal perception during dynamic visual experiences; hence, they lead to the hypothesis that the experience of time in audiovisual media is linked to the perceptual management of the movements / transformations artificially introduced by the medium. Furthermore, they provide novel insight into how brain stimulation can shape the perception of time in film.
