La Terre est un jardin bordé de nuit. Tels des aveugles nous avançons, mais sûrs de nous, fiers, cruels, consommateurs, assoiffés de profit. Modernes? Que restera-t-il à nos enfants de cette oasis si humaine? Seront-ils seulement là pour contempler nos méfaits? Verront-ils, comme nous, les fleurs, le désert, le ciel aux mille étoiles, la vie menacée, la guerre? Théodore Monod - qui avait seize ans quand les cloches de France sonnèrent la paix en 1918 - nous offre une méditation lucide (...) et pleine d'espoir. Il se bat aujourd'hui comme il l'a toujours fait. Et nous dit : ne mourons pas résignés devant nos ordinateurs. Dans le silence. Dans nos lits. Battons-nous. Cherchons le beau, le vrai. Ayons enfin le courage des larmes. Et révérons la vie. (shrink)

We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes. To give a comprehensive account of the nature of odors the chemosciences must account for these large distributed entities as well. We offer a focused review of (...) what is known about the perception of odor plumes for olfactory navigation and tracking, which we then connect to what is known about the role odorants play as properties of the plume in determining odor identity with respect to odor quality. We end by motivating our central claim that more research needs to be conducted on the role that odorants play within the odor plume in determining odor identity. (shrink)

Olfaction represents odors, if it represents anything at all. Does olfaction also represent ordinary objects like cheese, fish and coffee-beans? Many think so. This paper argues that it does not. Instead, we should affirm an austere account of the intentional objects of olfaction: olfactory experience is about odors, not objects. Visuocentric thinking about olfaction has tempted some philosophers to say otherwise.

It is arguably the case that olfactory system contains two senses that share the same type of stimuli, sensory transduction mechanism, and processing centers. Yet, orthonasal and retronasal olfaction differ in their types of perceptible objects as individuated by their sensory qualities. What will be explored in this paper is how the account of orthonasal smell developed in the Molecular Structure Theory of smell can be expanded for retronasal olfaction (Young, 2016, 2019a-b, 2020). By considering the object of olfactory perception (...) to be the molecular structure of chemical compounds composing odor plumes, Molecular Structure Theory provides a means for determining an odor’s olfactory quality, how odors can be identified and individuated, and how we perceive smellscapes. Surveying the differences between orthonasal and retronasal olfaction provides the basis for the central argument of the paper that the perceptible objects we refer to as smells and individuated on the basis of their olfactory qualities are only relative to orthonasal olfaction. Retronasal olfaction it is speculatively concluded might play an essential role in our perception of flavorful objects. (shrink)

Odor and color are strongly associated. Numerous studies demonstrate consistent odor‐color associations, as well as effects of color on odor perception and language. Yet, we know little about how these associations arise. Here, we test whether language is a possible mediator of odor‐color associations, specifically whether odor‐color associations are mediated by implicit odor naming. In two experiments, we used an interference paradigm to prevent the verbalization of odors during an odor‐color matching task. If participants generate color associations subsequent to labeling (...) an odor, interfering with verbalization during the task should affect the ability to make color associations. In Experiment 1, contrary to our hypothesis, verbal interference did not affect odor‐color matches. However, since performance accuracy on the verbal interference task was high, it is possible our task did not sufficiently disrupt verbal processing. In Experiment 2, we, therefore, used an active verbal interference task, and still found no difference across interference conditions. Odor naming accuracy, odor familiarity, and odor pleasantness, however, did predict odor‐color matches. This suggests that although color associations are related to semantic factors, they are not generated by recruiting odor labels in the moment. Overall, our results do not provide evidence that language plays an online role in odor‐color associations, instead, they are consistent with the claim that language may have shaped associations during development.

Scientists have shown that many non‐human animals such as ants, dogs, or rats are very good at using smells to find their way through their environments. But are humans also capable of navigating through their environment based on olfactory cues? There is not much research on this topic, a gap that the present research seeks to bridge. We here provide one of the first empirical studies investigating the possibility of using olfactory cues as landmarks in human wayfinding. Forty subjects participated (...) in a piloting study to determine the olfactory material for the main experiment. Then, 24 subjects completed a wayfinding experiment with 12 odors as orientation cues. Our results are astonishing: Participants were rather good at what we call “odor‐based wayfinding.” This indicates that the ability of humans to use olfactory cues for navigation is often underestimated. We discuss two different cognitive explanations and rule out the idea that our results are just an instance of sequential learning. Rather, we argue that humans can enrich their cognitive map of the environment with olfactory landmarks and may use them for wayfinding. (shrink)

Smell denomination and identification are well-known issues. Our first interest of study within this subject field is the denominative situation including names of odors. These are not real odoronyms but they are divided into two categories: on one hand, general names are functioning as the noun “odor” and on the other hand, fake names of smells are fulfilling the role of specifying odors. Secondly we will argue that particuliar and specific odors are usually identified through “odor of N”. We will (...) study its construction, specifications and we will investigate some causes of its success. (shrink)

Background: Olfactory cues directly link the environment to gene expression. Two types of olfactory cues, food odors and social odors, alter genetically predisposed hormone-mediated activity in the mammalian brain. Methods: The honeybee is a model organism for understanding the epigenetic link from food odors and social odors to neural networks of the mammalian brain, which ultimately determine human behavior. Results: Pertinent aspects that extend the honeybee model to human behavior include bottom-up followed by top-down gene, cell, tissue, organ, organ-system, and (...) organism reciprocity; neurophysiological effects of food odors and of sexually dimorphic, species-specific social odors; a model of motor function required for social selection that precedes sexual selection; and hormonal effects that link current neuroscience to social science affects on the development of animal behavior. Conclusion: As the psychological influence of food odors and social orders is examined in detail, the socioaffective nature of olfactory cues on the biologically based development of sexual preferences across all species that sexually reproduce becomes clearer Keywords: behavior; development; evolution; odors; food; social; sexual; epigenetic; olfaction; pheromones; hormones; environment; animal; affect; effect; neuroscience (Published: 15 March 2012) Citation: Socioaffective Neuroscience & Psychology 2012, 2 : 17338 - DOI: 10.3402/snp.v2i0.17338.

The understanding of food cue associated neural activations that predict future weight variability may guide the design of effective prevention programs and treatments for overeating and obesity. The current study investigated the association between brain response to different food odors with varied energy density and individual changes of body mass index (BMI) over two years. Twenty-five participants received high-fat (chocolate and peanut), low-fat (bread and peach) food odors and a nonfood odor (rose) while the brain activation was measured using functional (...) magnetic resonance imaging (fMRI). BMIs were calculated with participant’s self-reported body weight and height collected at the time of fMRI scan and again at two years later. Regression analyses revealed significant negative correlations between BMI increase over 2 years and brain activation of the bilateral precuneus and the right posterior cingulate cortex in response to high-fat versus low-fat food odors. In addition, brain activation of the right supplementary motor area in response to food vs non-food odor was negatively correlated to subsequent BMI increase over 2 years. Taken together, the current findings suggest that individual differences in neural responsivity to (high calorie) food odors in brain regions of the default mode and motor control network serve as a neural marker for future BMI change.

People positively appraise odors of individuals who are genetically different from themselves. Here we analyzed the relationship between perceived similarity of body odor to the judges’ relatives and their partners, and characteristics attributed to the odor donor. Seventy-six women were asked to smell one of the scents of twenty-nine men, and rate variables related to potential sexual interest in odor donor. We hypothesized that characteristics related to potential sexual interest would be associated with odor donors smelling similar to a partner, (...) rather than with odor donors smelling similar to a relative. We found that perceived similarity to a partner’s scent was positively correlated with ratings of variables related to potential sexual interest in odor donor, whereas the resemblance to a close relative’s scent did not correlate with these assessments.

Odor detection and identification by machines is currently being done to evaluate perfumes, wine, olive, oil, and even find people buried in rubble. Extending body odor detection to authentication may seem far-fetched and unrealistic. Yet such an application is plausible, given that like a fingerprint or iris, the human body odor is unique. Although such technology still has strides to make before being applicable as either a stand-alone or supplemental technology to existing biometric tools, it still warrants research, especially in (...) how the technology is perceived. Numerous studies have addressed the public perception of biometric technologies, although odor scanning is one that has been under-addressed. This exploratory study addresses perceptions and attitudes of odor scanning and recommends directions for future research and practice. This study has found that odor scanning is little understood, and its benefit to security and privacy are perceived as low. Should body odor scanning develop into a viable method of biometric authentication, issues of perception and acceptance will need further attention by both research and practice. (shrink)

The evolutionist theories of Bachofen on the priority of matriarchy are today no more than one of the most unusual pieces of the historical museum of anthropology. The wealth and diversity of historical and literary sources therein are juxtaposed with the construction of a conjectural chronology organizing the relationship between the sexes in a progressive mode and in accordance with an immanent finality. But it is also necessary to distinguish, on the one hand, Bachofen's historicism as an expression of the (...) evolutionist tendencies of that time, based on natural sciences and the results of Darwin's work, and, on the other, interest in the inter-sexual relationship within the social institution. For the invention of successive stages in order to propose a social history of sexuality is based as much on evolutionism as on constitutive psychic representations of the individual. By projecting these representations into a pseudo-historical period and by ordering them, at each level, in terms of the two parameters of domination / subjection and collectivity / individuality, Bachofen assigned semantics to history and an evolutionary sense to transformations in marriage and the family. And by conferring historical validity on the myths of Antiquity, he set forth an implicit denial both of the work of the imagination (not to say sub-conscious, which would be an anachronism for this pre-Freudian period) as well as of ideological ruses in the political field. Bachovian evolutionism thus developed a new myth out of the ancient myths, false witnesses of the past but authentic representatives of the ahistorical present of the psyche, endowing with scientific color the image of humanity progressing from dominance of the mother and collectivism to the triumph of the father and individualism. The idea of “matriarchy” (Mutterrecht) in Bachofen is indeed to be taken in the sense of “maternal dominance” (as the German expression better suggests), and not that of political power of women.

We propose the mereological theory of odors, according to which odors are proper parts of concrete objects. We distinguish between object solid core and gaseous periphery; the odor is the periphery and plays a role in olfactory perception similar to the role played by surfaces in visual and tactile perception. Some epistemological and metaphysical consequences of the theory are explored, in particular the fact that objects are larger than they visually appear, and that smell turns out to be more accurate (...) than both vision and touch. In the context of dealing with infectious diseases transmitted by airborne particles, a reconceptualization of odors could be leveraged for inducing better mental representations and protective measures.

The vocabulary for describing odors in English natural language is not well understood, as prior studies of odor descriptions have often relied on preselected descriptors and odor ratings. Here, we present a data-driven approach that automatically identifies English odor descriptors based on their degree of olfactory association, and derive their semantic organization from their distributions in natural texts, using a distributional-semantic language model. We identify 243 descriptors that are much more strongly associated with olfaction than English words in general. We (...) then derive the semantic organization of these olfactory descriptors, and find that it is captured by four clusters that we name Offensive, Malodorous, Fragrant, and Edible. The semantic space derived from our model primarily differentiates descriptors in terms of pleasantness and edibility along which our four clusters are positioned, and is similar to a space derived from perceptual data. The semantic organization of odor vocabulary can thus be mapped using natural language data (e.g., online text), without the limitations of odor-perceptual data and preselected descriptors. Our method may thus facilitate research on olfaction, a sensory system known to often elude verbal description. (shrink)
