Personal and home care products are nowadays similar in terms of hedonic value and performance. In this context, the consideration of their emotional value, in harmony with consumer expectations, can be a differentiating factor for fragrance development. This chapter aims at providing examples that show how emotional responses to odors, personal products, and home care products can be measured. After describing the strong influence of olfaction on emotional processing and the role of associative learning, we propose a definition of emotion and feelings. We focus on feelings, or the verbalization of emotions, by mainly referring to the conscious part of the emotional response elicited by odors and fragranced products. Although the unconscious part of the emotional response related to physiological and behavioral responses should not be underestimated, this topic is covered in Part 1 of the book, which is dedicated to the basic studies of emotions. The current chapter provides a review on a methodology developed to measure food-elicited feelings or fragrance-elicited feelings, with consideration of cross-cultural differences. Fundamental questions and critical choices that arise when such a démarche is undertaken are also highlighted. A series of results is presented to illustrate the use of this methodology in sensory settings for product development. Finally, we propose that investigations should be undertaken into the effects of changing the product label, packaging, and color of the fragranced products on consumer emotional expectations and on the overall emotional response when the product is experienced.
