Body odor disgust sensitivity
Odors are important disease cues, and disgust sensitivity to body odors reflects individual differences in disease avoidance. The body odor disgust sensitivity (BODS) scale provides a rapid and valid assessment of individual differences. Nevertheless, little is known about how individual differences in BODS might correlate with overall odor perception or how it is related to other differences in emotional reactivity (e.g., affect intensity). We investigated how BODS relates to perceptual ratings of pleasant and unpleasant odors. We aggregated data from 4 experiments (total N = 190) that were conducted in our laboratory, and where valence and intensity ratings were collected. Unpleasant odors were body-like (e.g., sweat-like valeric acid), which may provide disease cues. The pleasant odors were, in contrast, often found in soap and cleaning products (e.g., lilac, lemon). Across experiments, we show that individuals with higher BODS levels perceived smells as more highly valenced overall: unpleasant smells were rated as more unpleasant, and pleasant smells were rated as more pleasant. These results suggest that body odor disgust sensitivity is associated with a broader pattern of affect intensity which causes stronger emotional responses to both negative and positive odors. In contrast, BODS levels were not associated with odor intensity perception. Furthermore, disgust sensitivity to odors coming from external sources (e.g., someone else's sweat) was the best predictor of odor valence ratings. The effects were modest in size. The results validate the BODS scale as it is explicitly associated with experimental ratings of odor valence.

A politics of disgust : selfhood, world-making, and ethics
\"This book explores the intersubjective nature of disgust, the fascination that often accompanies it -- along with repulsion -- and the ethical implications of the experience. With attention to what emotions do rather than what they necessarily are, it examines the ways in which disgust works to create structures of meaning about selfhood, interpersonal relationships, and the worlds we inhabit. Offering a critique of existing approaches to disgust, the author advances a feminist intersubjective perspective, drawing on the work of Jessica Benjamin to understand the relational aspects of disgust encounters. Thus, the focus is not on defining disgust definitively, nor debating what objects invoke disgust, nor on whether it is a universal experience, but on the effects of disgust once invoked, what the experience does and the impact it has. Through a case study of incarceration and death by self-inflicted strangulation - a death that was later ruled a homicide - this volume sheds light on the nature of the ethical demands of disgust and its nature as an active struggle for recognition. As such, A Politics of Disgust will appeal to scholars of gender studies, social theory and philosophy with interests in the emotions and intersubjectivity\"-- Provided by publisher.

The Psychological and Neural Basis of Loss Aversion
Loss aversion is a central element of prospect theory, the dominant theory of decision making under uncertainty for the past four decades, and refers to the overweighting of potential losses relative to equivalent gains, a critical determinant of risky decision making. Recent advances in affective and decision neuroscience have shed new light on the psychological and neurobiological mechanisms underlying loss aversion. Here, integrating disparate literatures from the level of neurotransmitters to subjective reports of emotion, we propose a novel neural and computational framework that links norepinephrine to loss aversion and identifies a distinct role for dopamine in risk taking for rewards. We also propose that loss aversion specifically relates to anticipated emotions and aspects of the immediate experience of realized gains and losses but not their long-term emotional consequences, highlighting an underappreciated temporal structure. Finally, we discuss challenges to loss aversion and the relevance of loss aversion to understanding psychiatric disorders. Refining models of loss aversion will have broad consequences for the science of decision making and for how we understand individual variation in economic preferences and psychological wellbeing across both healthy and psychiatric populations.

Annoying : the science of what bugs us
\"Two crackerjack science journalists from NPR look at why some things (and some people!) drive us crazy It happens everywhere? offices, schools, even your own backyard. Plus, seemingly anything can trigger it cell phones, sirens, bad music, constant distractions, your boss, or even your spouse. We all know certain things get under our skin. Can science explain why? Palca and Lichtman take you on a scientific quest through psychology, evolutionary biology, anthropology, and other disciplines to uncover the truth about being annoyed. What is the recipe for annoyance? For starters, it should be temporary, unpleasant, and unpredictable, like a boring meeting or mosquito bites Gives fascinating, surprising explanations for why people react the way they do to everything from chili peppers to fingernails on a blackboard Explains why irrational behavior (like tearing your hair out in traffic) is connected to worthwhile behavior (like staying on task) Includes tips for identifying your own irritating habits! How often can you say you're happily reading a really Annoying book? The insights are fascinating, the exploration is fun, and the knowledge you gain, if you act like you know everything, can be really annoying.\"-- Provided by publisher.

Risk, Uncertainty, and Entrepreneurship: Evidence from a Lab-in-the-Field Experiment
Theory predicts that entrepreneurs have distinct attitudes toward risk and uncertainty, but empirical evidence is mixed. To better understand the unique behavioral characteristics of entrepreneurs and the causes of these mixed results, we perform a large “lab-in-the-field” experiment comparing entrepreneurs to managers (a suitable comparison group) and employees (
n
= 2,288). The results indicate that entrepreneurs perceive themselves as less risk averse than managers and employees, in line with common wisdom. However, when using experimental incentivized measures, the differences are subtler. Entrepreneurs are only found to be unique in their lower degree of loss aversion, and not in their risk or ambiguity aversion. This combination of results might be explained by our finding that perceived risk attitude is not only correlated to risk aversion but also to loss aversion. Overall, we therefore suggest using a broader definition of risk that captures this unique feature of entrepreneurs: their willingness to risk losses.

Objection : disgust, morality, and the law
\" Why do we consider incest wrong, even when it occurs between consenting adults unable to have children? Why are words that gross us out more likely to be deemed \"obscene\" and denied the protection of the First Amendment? In a world where a gruesome photograph can decisively influence a jury and homosexual behavior is still condemned by some as \"unnatural,\" it is worth asking: is our legal system really governed by the power of reason? Or do we allow a primitive human emotion, disgust, to guide us in our lawmaking? In Objection, psychologists Debra Lieberman and Carlton Patrick examine disgust and its impact on the legal system to show why the things that we find stomach-turning so often become the things that we render unlawful. Shedding light on the evolutionary and psychological origins of disgust, the authors reveal how ancient human intuitions about what is safe to eat or touch, or who would make an advantageous mate, have become co-opted by moral systems designed to condemn behavior and identify groups of people ripe for marginalization. Over time these moral stances have made their way into legal codes, and disgust has thereby served as the impetus for laws against behaviors almost universally held to be \"disgusting\" (corpse desecration, bestiality) - and as the implicit justification for more controversial prohibitions (homosexuality, use of pornography). Written with a critical eye on current events, Lieberman and Patrick build a case for a more reasoned approach to lawmaking in a system that often confuses \"gross\" with \"wrong.\" \"-- Provided by publisher.
