Previous research has demonstrated that short film clips are effective stimuli for emotion elicitation (e.g., Gross & Levenson, 1995; Schaefer et al., 2010). A recent study on self-report measures showed that film clips can elicit target emotions at moderate to high levels even when specific physical characteristics, such as color, sound, and translation method, are altered (Arikan-İyilikci et al., 2024). However, recent studies have also found a significant role of physical properties using neuroimaging (e.g., color versus black-and-white, Cao et al., 2024) or psychophysiological measures (e.g., standard subtitles versus aesthetically integrated subtitles, Leveridge et al., 2024). To contribute to this emerging literature, this study will investigate how changes in different physical characteristics and their combinations affect emotion elicitation, using functional near-infrared spectroscopy (fNIRS). By combining fNIRS with self-report measures, this study aims to provide a more in-depth understanding of emotional responses (i.e., target and non-target emotions, arousal, and valence). Additionally, as previous research has primarily focused on highly successful film clips, this study further aims to examine whether the effects of physical properties differ between film clips eliciting target emotions at intense versus moderate levels. It is hypothesized that such physical changes in film clips might play a more significant role in self-reported emotional responses when moderately, but not intensely, emotion-evoking scenes are used.
