Researchers often tend to use the words emotions, feelings, moods, and affect interchangeably, which creates confusion in both conceptual and methodological domains of tourism and hospitality research. However, the insights from neuroscience and psychology demonstrated that there are fundamental differences between these concepts, including their causes, duration, intensity, and outcomes. This research note aims to discuss conceptual and methodological aspects related to using emotions, moods, feelings, and affect, provide comprehensive definitions, and outline opportunities to capture them comprehensively in tourism and hospitality research.
