Making Sense of Scents: Smell and the Brain. In a survey of 7,000 young people around the world, about half of those between the age of 16 and 30 said that they would rather lose their sense of smell than give up access to technology like laptops or cell phones. "We're not that acutely aware of our use of olfaction in daily living," explains Noam Sobel, a scientist who studies smell at the Weizmann Institute of Science. But 5 percent of our DNA is devoted to olfaction, a fact that emphasizes how important our sense of smell is, he said. The Nose Knows Smell begins at the back of nose, where millions of sensory neurons lie in a strip of tissue called the olfactory epithelium. The tips of these cells contain proteins called receptors that bind odor molecules.

People have about 450 different types of olfactory receptors. "Think of a lock that can be opened by 10 different keys. The complexity of receptors and their interactions with odor molecules are what allow us to detect a wide variety of smells. Odors in the Brain A Better Smeller. Aux origines des émotions : les neurosciences affectives. En 1998, Jaak Panksepp publiait un ouvrage de référence dont le titre, “Affective Neuroscience” (les neurosciences affectives, en français), allait devenir l’expression consacrée pour ce « jeune » champ de recherche qui étudie les mécanismes neuronaux derrières nos émotions. Jeune, parce qu’on a longtemps considéré les émotions comme quelque chose se situant en dehors du champ d’investigation scientifique.

Mais ce n’est plus le cas, et « The Archaeology of Mind: Neuroevolutionary Origins of Human Emotions”, que Panksepp vient de publier confirme dans un langage accessible à un public plus vaste la pertinence et l’intérêt grandissant des neurosciences affectives défrichées il y a près de 15 ans dans son livre éponyme. Et un moyen encore plus rapide de prendre contact avec les thèses de Panksepp, c’est d’écouter le récent entretien qu’il a accordé à Ginger Campbell pour le 91e épisode du toujours très attendu Brain Science Podcast. Que d'émotions! | 6 commentaires » Reversal theory. Introduction[edit] Reversal theory[1] is a theory of personality, motivation and emotion in the field of psychology. It focuses on the dynamic qualities of normal human experience to describe how a person regularly reverses between psychological states, reflecting their motivational style and the meaning they attach to a given situation at a given time.[2] For example, sometimes a roller coaster seems exciting; other times, it may cause anxiety.

Sometimes a crying baby creates sympathy; other times it causes irritation. The theory distinctively proposes that human experience is structurally organized into metamotivational domains, of which four have been identified. Each domain consists of a pair of opposing values or motives, so that only one of each pair can be experienced in any given moment.[2] Reversal theory has been developed primarily by British psychologist Dr.

Domains[edit] The four pairs (or domains) are as follows: Reversals and emotion[edit] Dominance[edit] References[edit] Ryan Musselman MFA Thesis.

Customers will, therefore, base their decisions on more subjective factors. Moreover, in the future, products will consist, to a higher grade, of a combination of a tangible and intangible part. Kansei Engineering is a tool translating customer's feelings into concrete product parameters and provides support for future product design. Presently, a total of six different types of Kansei Engineering are in use. The aim of this paper is to propose a framework in Kansei Engineering to facilitate the understanding of the different types of Kansei Engineering and to open Kansei Engineering for the integration of new tools.
