Development and validation of a natural dynamic facial expression stimulus set

Abstract

Emotion research commonly uses either controlled and standardised pictures or natural video stimuli to measure participants’ reactions to emotional content. Natural stimulus materials can be beneficial; however, certain measures such as neuroscientific methods, require temporally and visually controlled stimulus material. The current study aimed to create and validate video stimuli in which a model displays positive, neutral and negative expressions. These stimuli were kept as natural as possible while editing timing and visual features to make them suitable for neuroscientific research (e.g. EEG). The stimuli were successfully controlled regarding their features and the validation studies show that participants reliably classify the displayed expression correctly and perceive it as genuine. In conclusion, we present a motion stimulus set that is perceived as natural and that is suitable for neuroscientific research, as well as a pipeline describing successful editing methods for controlling natural stimuli.

Muslim fashion dynamics: The mediating role of positive emotion in elucidating impulsive buying behavior

“…Fashion involvement serves as a critical factor influencing the relationship between positive emotion and consumer behavior. Researchers utilize various methodologies, such as willingness-to-pay approaches (Lau et al, 2013), physiological polygraphs (Mo & Luh, 2023), and natural dynamic facial expression stimulus sets (Pasqualette et al, 2023), to quantify and understand the value of emotions in the realm of fashion. The interplay between positive emotion and consumer behavior is a central theme in the reviewed literature.…”
