Measuring emotions triggered by fragrance through behavioral paradigms

Area of Science:

• Psychology
• Neuroscience
• Sensory Science

Background:

• Fragrance positively influences emotions, experiences, and behaviors.
• Previous research primarily used physiological or subjective measures.
• Behavioral methods for assessing fragrance-induced emotions are underexplored.

Purpose of the Study:

• To explore the measurement of emotional responses to fragrance using behavioral paradigms.
• To investigate the consistency between behavioral measures and physiological data (EEG).

Main Methods:

• A self-controlled experiment involving participants smelling various fragrances.
• Assessment of emotional changes using electroencephalography (EEG), emotion scales, and behavioral tasks (Go/No-go Association Task, time bisection task).

Main Results:

• Behavioral measures (Go/No-go Association Task, time bisection task) showed consistency with EEG-derived emotional valence and arousal.
• Exposure to orange fragrance significantly increased EEG valence (p=0.017) and temporal dilation (p=0.038).

Conclusions:

• Behavioral paradigms can effectively assess emotional valence and arousal changes in response to fragrances.
• Findings support the use of behavioral methods in fragrance product development and multisensory experience enhancement.
