Aversion and Attraction through Olfaction
Sensory cues that predict reward or punishment are fundamental drivers of animal behavior. For example, attractive odors of palatable food or a potential mate predict reward, while aversive odors of pathogen-laced food or a predator predict punishment. Aversive and attractive odors can be detected by intermingled sensory neurons that express highly related olfactory receptors and display simila...
متن کاملIndividual glomeruli mediate innate olfactory attraction and aversion in Drosophila
Abstract: In the Drosophila olfactory system, as in many other organisms, different odorants activate specific patterns of glomeruli, but the mechanisms by which these patterns are transformed and eventually read out to lead to behavior remain unknown. One outstanding question is the degree to which the responses of the second order projection neurons are derived from direct receptor input, as ...

Does risk attitude (aversion or attraction) vary with the level of the income at risk? About half of our subjects chose to insure all levels, whereas another half chose instead not to insure low levels, but to insure high levels.
متن کاملOvercoming Ambiguity Aversion Through Experience
Ambiguity is often characterized with unknown probability distributions (for potential outcomes), which people avoid while making decisions. Existing literature shows that ambiguity aversion often persists even when these probability distributions are explicitly described to decision makers. We test the hypothesis that exposure to these probability distributions via sampling experience, rather ...
متن کاملAversion, awareness, and attraction: investigating claims of hyperacusis in the Williams syndrome phenotype.
BACKGROUND Williams syndrome (WS), a neurodevelopmental disorder, is characterized by pervasive cognitive deficits alongside a relative sparing of auditory perception and cognition. A frequent characteristic of the phenotype is adverse reactions to, and/or fascination with, certain sounds. Previously published reports indicate that people with WS experience hyperacusis, yet careful examination ...
