Arousal and valence in the direct scaling of emotional response to film clips

Contributions of differential attention to valence versus arousal (Feldman, 1995) in self-reported emotional response may be difficult to observe due to (I) confounding of valence and arousal in the labeling of rating scales, and (2) the assumption of an interval scale type. Ratings of emotional response to film clips (Ekman, Friesen, & Ancoli, 1980) were reanalyzed as categorical (nominal) in scale type using consensus analysis. Consensus emerged for valence-related scales but not for arousal scales. Scales labeled Interest and Arousal produced a distribution of idiosyncratic responses across the scale, whereas scales labeled Happiness, Angel; Sadness, Fear Disgust, Surprise, and Pain, produced consensual response. Magnitude of valenced response varied with both stimulus properties and self-reported arousal.
